Telephone code (Germany)

from Wikipedia, the free encyclopedia
Area codes in Germany

The telephone prefixes in Germany include 5202 local networks , five number ranges for mobile communications and several special numbers . They are (today ) organized and awarded by the Federal Network Agency (BNetzA).


The area codes are given including the national traffic elimination number ( prefix ) "0", as they are usually dialed for telephone calls within Germany . In official usage, area codes are further differentiated in terms of content. Examples:

  • 030 12345678 Local network number (Berlin)
    The area code 030 consists of the prefix "0" + local area code (ONKz) "30"
  • 0170 1234567 Mobile number (Deutsche Telekom)
    The area code 0170 consists of the prefix "0" + service code "17" + block identifier "0"
  • 0180 1 123456 special number (shared cost 3.9 cents / minute)
    The prefix 01801 consists of the prefix "0" + service code "180" + tariff code "1"

For calls from abroad , the national traffic elimination number "0" is omitted. Examples:

The caller must replace the plus sign “+” with the currently valid international traffic elimination number; For example "00" for calls from Europe to other countries or "011" for calls from North America to other countries.

When the German preselection system was introduced, the long-distance switching network, based on analog switching technology, was structured hierarchically on several levels, with each selected digit of the local network code being evaluated individually and corresponding to one of the hierarchical levels (central switching center, main switching center, nodal switching center and local switching center). This earlier hierarchy is therefore still recognizable today in the West German dialing codes, see exchange .

In the fixed network , a number can usually be dialed within the same local area network without an area code. This does not work in cellular networks.

Since the introduction of number portability , the selected network or the connection operator can no longer be determined with certainty based on the area code. However, since the tariff often depends on this, many connection operators offer information services (e.g. via freecall or SMS) that display the tariff-relevant affiliation to a phone number.

The area covered by an area code does not match the city and municipality boundaries. In some cases, several municipalities are combined under one code and parts of a municipality can have their own code or share it with a neighboring municipality. In some cases the borders of the federal states are also exceeded.

Preselection ranges

For historical reasons, area codes are only in the area code ranges 02 to 09. They were officially set and historically published in the Official Directory of Area Codes (AVON). Special numbers are mainly located in the 01 area code. Important exceptions are the area codes 032, 0700, 0800 and 0900. 00 is the international traffic elimination number.

Short numbers

Abbreviated numbers can be dialed anywhere in Germany, and most of them also have origin-dependent routing (e.g. 110). Contrary to the general number range with area codes, you have your own number range , e.g. B. Elfer-Gasse.

Changes in the course of German reunification

Until German unification, each of the two German states had their own systems for telephone prefixes. However, there was no reform here, as by expanding the area code to six digits (including a leading zero), enough area code numbers in the area “03” (previously only used in the form of “030” for Berlin) were available, through which the previous GDR was available - Area codes replaced. The international code "+37" for the GDR was dropped with the reform. Reforms of primary elections are generally only carried out very restrictively and were also rare in the Federal Republic before 1990. When the area codes were changed in the new federal states, the numbers were retained as far as possible. From June 1, 1992, only the new area codes were eligible.
