Paging name

from Wikipedia, the free encyclopedia

The radio call name is the identification of a mobile or stationary radio station in the radio operation of the authorities and organizations with security tasks (BOS) . Station names in international radio traffic, however, are called call signs .

Germany (analog BOS radio)

Since regulated naming is particularly important in larger radio networks and in the case of supra-regional cooperation between mobile radio stations, a uniform nationwide system for naming radio stations was developed and recommended to the federal states for introduction in 1979 . The distribution of the radio call names is in the hands of the federal states, but it is usually based on a nationwide scheme. Call signs are issued by the national telecommunications authorities for transnational radio services .

Non-police BOS

In the case of the non-police authorities and organizations with security tasks (BOS), the designation usually takes place using a three-part scheme of the form:

  • Authority or organization password
  • Identification of the area of ​​application (location identification)
  • tactical index

An example would be the paging name Florian Stuttgart 11 / 42-1 . This has the following meaning:

meaning example Remarks
1 Authority or organization password "Florian" for fire brigade units in 4 meter tape
2 Identification of the area of ​​application (location identification) "Stuttgart" for the city of Stuttgart
3 a Location (for multiple locations) "11" for Department 11 (Birkach)
b Type of radio station or vehicle type "42" Fire fighting vehicle 8/6
c Consecutive number to differentiate between the same radio stations or vehicles at the same location 1 1. Type 42 vehicle

Point 3c is usually only used in the case of multiple vehicles and is otherwise omitted. The third digit can still be used (depending on the guideline and federal state). Point 3a can also be omitted for fire brigades with only one location.

Authorities and organizations passwords

The passwords of the non-police units in the BOS radio are:

organization 4 m band and digital radio 2 m tape
fire Department Florian Florentine / Florian (depending on the state)
German Red Cross Red cross Aesculapius
Johanniter Accident Aid Acre Jonas / Akkon (depending on the state)
Maltese relief service John Malta / Johannes (depending on the state)
Workers Samaritan Association Sama / Samuel Samuel / Sama (depending on the state)
technical aid organization hero Heros (old: Hermione )
German Life Saving Society pelican Adler (company radio) / Pelikan (depending on the state)
German Society for the Rescue of Shipwrecked People Triton
Rescue helicopter Christoph Christoph
Water watch Water watch Wasserwacht / Neptune (depending on the state)
Mountain Rescue Mountain Rescue Mountain Rescue
Civil protection authorities and units
of air protection emergency service
dike associations
KatS or hangover Katharina / Kater (depending on the state)
Leopold Leopoldine
Hydra Hydra
Municipal and private rescue services rescue rescue
Rescue dog squadron Antonius / Canis Antonius / Canis
PSNV : emergency pastoral care / crisis intervention /
follow-up care for emergency services (ENS / VNE)
Rafael Rafael
Emergency command Salus
Rescue train (Deutsche Bahn AG) Rescue train Rescue train
Authorized bodies for digital radio of the federal states Tetra

In some cases, separate passwords are no longer used in the 2 m band. That of the 4 m tape is then adopted.

Identification of the area of ​​application (location codes)

This identifier is used to identify the radio traffic circle (deployment or control center area). It is not uniformly regulated in the federal states, but usually consists of the names of the municipality, city or district, administrative district or federal state that operates the office.

Tactical indicators

The code number after the BOS password and location identifier designates the tactical unit that is to be addressed in radio communications. It usually consists of two or three sub-key figures.

  • The first partial code denotes the local group or guard (in the case of several locations within a municipality) to which the tactical unit is assigned. Example:
11 stands for the local group Neudorf
  • The second partial code stands for the unit type (e.g .: vehicle type). Example:
11-83 stands for an ambulance from the Neudorf local group
  • The third partial code is only required if there are several identical units of the same type (e.g. several identical vehicles). For this, the individual units are now numbered consecutively. Example:
11-83 / 2 stands for the second ambulance of the local group Neudorf

At the suggestion of the Interior Ministers' Conference of 1994, a scheme is used in the Länder. However, the states are free in the actual allocation, so that there can be considerable deviations. In addition, there is a recommendation from the working group of heads of professional fire departments, which allocates the same grouping, but in some cases differs greatly in detail.

The recommendations are not used unmodified in any federal state (except in the area of ​​the emergency services).

Fire brigade tactical indicators

The sub-codes for the unit type (i.e. the second sub-code) are organized into groups. The first number group from 0 to 9 stands for personal or fixed radio devices, all other number groups stand for certain types of vehicles.

Number range Unit type Examples
01-9 Executives "1": City / municipality / district fire chief
10-19 Leadership and personnel transport "11": command vehicle , "19": crew transport vehicle
20-29 Tank and powder fire trucks "21": 16/24 door fire truck
30-39 Aerial rescue vehicles "33": turntable ladder 23/12
40-49 Fire fighting vehicles and portable fire pumps "42": Fire fighting vehicle 10/6
50-59 Equipment and equipment trolleys "50": pre-equipment vehicle
60-69 Hose trolleys, swap bodies "61": hose trolley 1000, "65": swap truck
70-79 Other fire engines "71": fire brigade crane
80-89 Ambulance vehicles "82": ambulance vehicle
90-99 ABC service / at special disposal "93": multi-purpose decontamination vehicle

The number groups and vehicle types are (almost) uniformly assigned to one another nationwide, with the exception of Hamburg and Lower Saxony, which deviate completely from this.

However, within a group of numbers, the allocation of numbers to vehicles is not uniform across Germany.

Tactical indicators of the Hamburg fire brigade

As a city-state, Hamburg uses a different system of paging names. It begins with the password "Florian" and the location identifier "Hamburg". In the case of a vehicle from a professional fire brigade, the respective watch number follows (e.g. "22" for the fire and rescue station Berliner Tor), in the case of volunteer fire brigades the full name (e.g. "Berliner Tor" for the volunteer fire brigade Hamburg Berliner Goal). After the guard, the respective vehicle is labeled. The respective vehicle type is specified here for the professional fire brigade and the special vehicles of the voluntary fire brigade. The fire engines of the voluntary fire brigade are assigned consecutive numbers.

  • Examples for the professional fire brigade:
  • Examples for the volunteer fire brigade:
    • "Florian Hamburg Berliner Tor 1" - first fire engine of the volunteer fire brigade Berliner Tor
    • "Florian Hamburg Lokstedt SW" - hose trolley of the Lokstedt volunteer fire department
    • "Florian Hamburg Neuwerk KB" - small boat of the Neuwerk volunteer fire brigade
  • In the case of rescue vehicles, letters according to the German spelling table are used
    • Anton: first ambulance (RTW) at this rescue station
    • Berta: second ambulance at this rescue station (etc.)
    • Friedrich, Gustav, Ida: Ambulance which is assigned to this fire and rescue station, but is stationed at a separate station (outpost) to guarantee the relief time
    • Kaufmann and Ludwig: Reserve ambulance, which is occupied by the crew of the fire engine, the other ambulance should already be in use
    • Paula and the following: Ambulance at a separate guard that is not manned by fire brigade personnel
  • Examples for the rescue service:
    • "Florian Hamburg 22 RTW A" - first RTW of the fire and rescue station Berliner Tor
    • "Florian Hamburg 14 RTW R" - first ambulance at the ASB ambulance station Osdorf (which drives on behalf of the professional fire brigade)
    • "Florian Hamburg 25 NEF A" - NEF of the fire and rescue station Billstedt, stationed at the BG Klinikum Boberg
Tactical indicators of the fire brigades in Lower Saxony (old system)

Lower Saxony also has (had) a different radio call name system for fire departments. Contrary to the three-part sequence of digits common in most federal states, only two-part sequences of digits are used in Lower Saxony. The first group of digits is either a regional (10..89) or a functional identifier (90..99). The second group of digits provides information about the type of radio station; the specified markings can be found in the table below:

Number range Vehicle type
10-19 Fire trucks
20-29 Fire fighting vehicles, relay fire fighting vehicles and portable fire pumps
30-39 other fire fighting vehicles (aerial rescue vehicles and hose trolleys)
40-49 Vehicles for technical assistance (equipment and equipment trolleys)
50-59 Vehicles of the fire service rescue service
60-69 Command vehicle
70-79 Handheld radios in the 4 m band
700-799 Handheld radios in the 2 m band
80-84 other fire engines (which are not sorted 30-39)

Additional identifiers in the second group of indicators can be assigned for local fixed radio stations in fire stations (e.g. 01-09), as well as for officials of municipal fire departments (90-99). This is up to the district, the independent city or the region.

Lower Saxony (new system) District Aurich fire brigade

  1. Digit area / municipality / city
  2. Number vehicle type / type
  3. Number station / guard / fire department

z. B. 10-11-1 is the ELW of the Aurich fire department in urban area 10 = urban area 11 = command vehicle 1 = Aurich fire department

In the course of the switch to digital radio, the radio call names in Lower Saxony are being adapted to the now almost national scheme.

Tactical indicators of the rescue service
Radio call names of the emergency vehicles (tactical identifiers) are often given on the rear or on the windshield, here an ambulance of the Bavarian Red Cross ("Rotkreuz Miesbach 43/71/3")

In the rescue service, tactical fire brigade codes (including 80–89) are sometimes used, or special codes that are tailored to the needs of the rescue service (e.g. special vehicles for water or mountain rescue). This depends on the federal state, if determined by it, or on the operator organization. At least in the case of IDs that the operator organization has determined itself, the IDs are uniform nationwide, except for the Bavarian and Hessian ones:

  • 81: NAW / ITW ( Bavaria : 70; Hesse : 81 for NAW / 87 for ITW)
  • 82: NEF (Bavaria: 76; Hesse: 82)
  • 83: RTW / MZF (Bavaria: 71; Hesse: 83 for ambulances that are manned 24 hours a day; 84 for ambulances that are not manned 24 hours a day, e.g. day service; 85 for ambulance vehicles that are not regularly and voluntarily manned)
  • 84: NKTW (Bavaria: 73; Hesse: 93)
  • 85: KTW (Bavaria: 72, Hesse: 91-92)
  • 86: Emergency ambulance of the disaster control units and not permanently manned (Bavaria: 71, Hesse: 85)
  • 87: KTW of the disaster control units (Bavaria: 72, Hesse: 91ff.)
Tactical indicators of the German life-saving society

Call names of the DLRG are composed in a similar way to fire brigade call names and are not uniform nationwide. The individual regional associations can issue special regulations for their areas. Many state associations have adopted the fire brigade scheme, others use the following scheme:

Number range Unit type
1-9 Fixed stations
10-39 no specific assignment
40-49 KatS vehicles, motor lifeboats
50-59 Motor vehicles
60-96 no specific assignment
97 Foot troops
98 Operations Manager
99 not forgiven

In a deployment at the state level, radio call names are assigned individually during deployment. As a rule, these are for example "Adler Rheinpfalz 98" (Operations Manager Rhineland-Palatinate), but they can also be assigned differently.

Tactical codes of fixed radio stations

Fixed radio stations , such as B. Telecommunication centers or operations control centers are designated according to the following scheme:

  • Identifier of the authority / location identifier - if applicable, sequential number

Example: Florian Hannover: Fire Brigade Operations Center Hannover

If an operations control center oversees several organizations, it usually only bears the name "Control Center".

Example: Control center XY: Fire and rescue service center XY

Some integrated control centers, such as those of the Hamburg fire brigade and the Cologne fire brigade, have the radio call name "Florian".

Police BOS

National Police

With the state police there is not always a classification according to tactical vehicle types. Often the vehicles are sorted there according to radio traffic circle and numbers, possibly in combination with letters. The radio circles are individually determined by the respective federal states and named according to different systems. Radio call names and ordinal numbers are regulated by the federal states (interior ministries).

For example, the first name in Baden-Württemberg before the introduction of digital radio consisted of a password for the regional council as the state police headquarters (Freiburg: Friedrich, Karlsruhe: Berta, Stuttgart: Dora and Tübingen: Uhland ), a distinguishing number for the police headquarters or the police headquarters and a number for the radio station. The number for the police headquarters was assigned in alphabetical order. The police headquarters in Heidelberg (Neckar 5), the police headquarters in Mannheim (Peter) and Karlsruhe (Günther), the Stuttgart police headquarters (Uran), the state criminal investigation office (Rubin), the water police ( Poseidon ), the police helicopter squadron (Bussard) and the riot police (Bruno) used different passwords. The special task force used the nickname Granit, although it was assigned to the riot police headquarters.

In Hamburg, on the other hand, a distinction is made between the police operations center with six radio circles (Michel 1 to 6), the police commissioners (Peter) and the helicopter squadron (Libelle), the criminal police (Kastor), state riot police (Alster), water protection police (Elbe) and special forces of the central directorates ( Zenith).

Federal agencies

  • Federal Police: The radio traffic groups are divided into federal police departments or inspections (e.g. Federal Police Directorate See: "Albatros")
  • Customs: Each main customs office is assigned a nickname. The customs offices also receive a number that increases in steps of ten (example: main customs office Hamburg-Freihafen: Hansa , customs office Cuxhaven-See: Hansa 10 , Helgoland branch: Hansa 10/2 ). Customs Criminal Police Office and Customs Investigation Offices all have the nickname "Pascha" with a distinguishing number (e.g. ZKA: 01, ZFA Freiburg 5)
  • Federal Foreign Office : Bamboo (mobile radio station)
  • Federal Ministry of the Interior : Dora (fixed radio station), Ferdinand (mobile radio station), trout, gondola (parliamentary state secretary), Habicht (state secretary), Lukas ( inspector of the federal police ), radon (state secretary), Randon (mobile radio station), Tanne (state secretary ), Zander (State Secretary)
  • Office of the Federal President : Kiefer
  • Feldjäger : Aurora
  • SAR service of the Bundeswehr: SAR (letters spoken individually)
  • Federal Office for Goods Transport : BAG (letters spoken individually), so far only department 1 - road control service - and department 4 - tolls -

Fire department in Germany

Digital BOS radio

In the digital BOS radio , each end device receives a unique operational-tactical address (OPTA), which is also transmitted to all receiving devices. This means that the radio call names are supplemented by a display on the radio set.


The OPTA is awarded according to a nationwide uniform scheme for the police and non-police BOS and consists of 24 digits that can be filled with numbers, letters or spaces. A distinction is made between the birth OPTA and the alias OPTA. Both are identical at the beginning and contain:

  • at positions 1 and 2: federal / federal state (e.g. "BU" for "federal", "SH" for "Schleswig-Holstein")
  • at positions 3–5: authority and organization identification (e.g. "POL" for "police", "FW␣" for "fire brigade")
  • at positions 6 to 8: regional allocation (city and district) (based on the vehicle registration number )

From position 9 the birth OPTA contains a unique sequence of digits and is permanently set. The alias OPTA can be freely defined within the rules and differs depending on the type of organization. It contains:

  • at positions 9 to 13: local assignment
  • at positions 14 to 21: function assignment (e.g. vehicle type, function, task)
  • at positions 22 and 23: order code (with the same location and function)
  • at position 24: addition


Since the radio call names in the digital BOS radio are partly based on the OPTA, there are usually changes to the call names compared to the analog BOS radio (example for the non-police BOS in the instructions for implementing the OPTA directive in North Rhine-Westphalia ). The organization passwords of the nickname (e.g. for the fire brigade "Florian", for the German Red Cross "Rotkreuz") are not part of the OPTA and are taken from the analog 4m band nickname system.

Example of radio call name formation using the OPTA (same local assignment):

  • Call name in the digital system: "Florian Erkrath 01/42/2" ("Florian Erkrath zero-one two-forty-two two")

or (according to the regulation depending on the federal state)

  • Radio call name in the digital system: "Florian Erkrath 01 HLF20 ​​2" ("Florian Erkrath zero-one HLF twenty two")
  • associated alias OPTA: NWFW ME ERK01HLF20 02

Example of radio call name formation based on the OPTA (changed local assignment):

  • Call name in the analog system: "Florian Sauerland 9/41/1" ("Florian Sauerland nine forty-one one")
  • Call name in the digital system: "Florian Bestwig 03 LF 1" ("Florian Bestwig zero-three LF one")
  • associated alias OPTA: NWFW HSKBSW03LF 01

Analog BOS radio

In the analog BOS radio, the radio call names differ between the control center radio (4m range) and the emergency station radio (2m range).

Control center radio

The control center radio covers the entire district.

  • Call name in the analog system: "Florian Erkrath 01/42/2" ("Florian Erkrath zero-one two-forty-two two")

or (depending on the regulations of the federal state)

  • Radio call name in the digital system: "Florian Erkrath 01 HLF20 ​​2" ("Florian Erkrath zero-one HLF twenty two")

In the 4m area, each district had two channels for the fire brigade. One was the general control center channel and the second was used as a guide channel for large-scale operations or major events. The control center is not integrated in the control channel itself. In their place, the main point of contact is the operations management and the operations management maintains the connection to the control center.

Operation site radio

The 2m range is only used on the scene because the range is very small. The range can be extended with relay points.

  • Call name in the analog system: e.g. B. Florentine Krüssau group leader

The location identifier and function are important here, and if the function is multiple, then also the serial number z. B. Florentine Krüssau Attack Troop 1 or 2.

The location identifier can be omitted if all units on the canal belong to the same location or a direct definition is made in a deployment section.

Conversion from analog to digital BOS radio

The analog BOS radio is (largely) replaced by the new digital BOS radio. However, until all fire brigade units have been converted to the new system, the old system will remain active. This means that the radio control centers work with two systems. It is possible to connect both systems by conference call so that fire brigades in the analog system can talk to those in the digital system and vice versa.


Since a standardized radio network for the BOS is currently only being set up in Austria , the individual organizations currently need to show relatively little consideration for one another.

Common names in organizations are:

Ambulance service

Every vehicle in the emergency service has a radio number. The first digit stands for the federal state (1 = Burgenland, 2 = Vienna, 3 = Lower Austria, 4 = Upper Austria, 5 = Styria, 6 = Tyrol, 7 = Carinthia, 8 = Salzburg, 9 = Vorarlberg) and is preceded by a point or followed by a hyphen. Then, depending on the federal state, there is a 3 to 5-digit vehicle number, which can also indicate the district office assigned to the vehicle. The individual offices are called with the place name and the control centers either with “control center”, “control center” + place name or with “state control center” (Styria). (In Lower Austria, 144 Emergency Call Lower Austria with the code name “Leo” is called. LEO is derived from the state patron Leopold.) In Burgenland, the LSZ Burgenland control center is called. LSZ is derived from the State Security Center. Similar to the NR 144. The LSZ handles all rescue and fire services. So z. B. in Salzburg called a vehicle with 208. The car number is 8.208, but the first digit is ignored within the federal state. In Styria, it is customary to call vehicles with the name of their local or district office and the vehicle number (e.g. "Leoben 12").

Example of the number identification in Upper Austria: 4.1551 (4 = federal state, 15 = district (in this case Steyr Stadt), 5 = local office, 1 = vehicle)

fire Department

While the place name is an integral part of the radio call name in the local fire brigade , the number of the respective unit is used in the disaster relief service .

The place or number is preceded by a short form of the name of the vehicle. For example, there are:

Call names in Salzburg

In Salzburg, the fire brigade radio always addresses the vehicles with the "tactical designation" and the "place name", similar to those in Styria and Burgenland. B. "Tank Elixhausen" for the fire truck or "Rüst St. Johann" for the rescue vehicle. If there are several vehicles of the same class in one place, these are numbered consecutively, e.g. B. "Tank 1 Saalfelden" or "Pump 2 Bischofshofen". The permanently manned radio station is the LAWZ (state alarm and warning center) with headquarters at the state fire brigade association in Salzburg. In contrast to other federal states, there is no integrated control center in Salzburg.

There are also five district alarm and warning centers (BAWZ), which are activated in the event of major incidents and manned by appropriately trained dispatchers. Your radio call name is "Florian" plus the name of the district z. B. "Florian Pinzgau" for the Zell am See district. Other fixed stations in the fire stations are called with "Florian" and the respective place name. These are only manned when deployed locally.

Radio call names in Burgenland

In Burgenland, the fire brigade radio always addresses the vehicles with the “tactical name” and the “place name”, similar to Styria. z. B. "Tank Podersdorf" for the tank tender or "Rüst Podersdorf" for the rescue vehicle. The permanently manned radio station is the LSZ (State Security Center) in Eisenstadt, which also handles all rescue operations. Fixed stations in the fire stations are called with "Florian" and the place name. These are only manned when an emergency occurs.

Call names in Lower Austria

Permanently manned radio stations, which are usually district alarm and warning centers (BAWZ), are designated with "Florian" and the place name, e.g. B. "Florian Baden" for the BAWZ of the Baden district. Stations that are not permanently manned, such as the individual fire brigades, are called with fire brigade plus place name , e.g. B. "Hainburg Fire Department". Mobile radio control centers are also designated with "Florian" and the number of the respective district where the control center is stationed. "Florian 14" is the mobile radio control center for the Mödling district. The state warning center (LWZ) is also addressed as "Florian Niederösterreich".

The radio call names of the individual vehicles and the handheld radios are made up of the radio call sign and the place name . Another vehicle in a category is also designated with 2, 3, .... For example “Pump Schlag”, “Anton Hirtenberg” or “Tank2 Zwettl”.

Radio call names in Styria

Radio call signs in Styria are basically composed of the radio call name (tactical designation) and the name of the fire brigade. Permanently manned radio stations are called with Florian + area name (the area florian stations) or Florian Steiermark (the state control center). In Styria, the vehicle type and the fire service name are always used for vehicle radios, e.g. B. "RLF Stainz " or "LF-B Wetzelsdorf". A fixed station that is occasionally occupied (in a fire station) is called the fire brigade + place name . A handheld radio in every fire brigade has the radio call sign emergency control + place name . The radio call signs for each additional handheld radio in the fire services are Alpha + place name (for the first handheld radio), Berta + place name (for the second), etc.

These handheld radios can, however, also be called after the tactical use + place name during fire service operations. Examples for this are:

  • Operations manager + place name
  • Pilot + place name
  • Respirator + place name

Individuals are called with rank + surname, e.g. B. Fire Councilor Maier

Radio call names in Tyrol

In Tyrol, the radio call sign or tactical designation and the fire department name are always used in fire service radio for vehicles , e.g. B. "TLF Fritzens" or "SRF Hall". If there are other vehicles of a category in a fire brigade, an additional 1, 2, 3, ... For example "LF-1 Wattens" or "TLF-2 Schwaz" A fixed station (in the fire station) is called "Florian + place name". Handheld radios are called with function + place name , e.g. B. "Operations Management Kufstein" or "Commander Telfs".

Due to a new Tyrolean Rescue Service Act, all rescue service operators must be dispatched and alerted by the Tyrol control center . Therefore, new, cross-organizational radio call names were required, which are structured as follows: RD / 14/115 where RD stands for the rescue service gGmbH, 14 describes the vehicle type (11: NEF, 12: REF, 13: RTW, 14: MZF, 15: KTW , 16: GKTW,…) and 115 is a consecutive number. The entire number must be used in the radio ("rescue fourteen-one-fifteen").

Radio call names in Vorarlberg

All rescue and fire service operations in Vorarlberg are handled by the rescue and fire brigade control center (RFL). Both organizations are alerted by means of digital message receivers. That is why the fire brigade centers that are called “Florian and place names” are not manned all the time, but only after the alarm has been raised. The vehicles are then called with the respective place name and tactical designation (e.g. Rankweil Tank1, or Altach LF).
