Postal logistics

With postal logistics logical concept is known, which uses a postal service to a postal item, fast error-free and cheap to transport from sender to receiver. The logical concept in the postal market is divided into three areas:

1. Collecting letters via mailboxes , branches or pick-up services

2. the transport of the mail to the region of delivery and

3. Delivery to the recipient, which is often referred to as "the last mile".

So that a letter that has been delivered to a postal service provider in Germany is sent to the correct delivery region , the sorting center only takes the spatial information from the address field in the order from coarse to fine:

1. Abroad or in Germany

2.1. if abroad, then special logistical channels come into consideration

2.2. if domestic, the region is searched for that is contained in the first two digits of the postcode (zip code).

This information is sufficient for the letter to take the right path. The information is in the correct region

3. About the city / town or the last three digits of the postcode and

4. then the street and house number are required in order to assign the letter to the correct delivery district and according to the order of delivery ( delivery route ).

The postman needs all further information in the address field, especially the name of the recipient .

Based on this logic, automatic sorting machines read the address field from bottom to top up to the street name and transfer the information to the envelope with their own coded machine font . In the mail center sorting center of the delivery region, the sorting machines there only need to read the coded machine font to assign the letter to the correct delivery district and then sort it into the correct delivery sequence for the deliverer.
