A Briefzentrum (English: Letter center) is a district center for the processing of letters for Deutsche Post.
Before 1993, there were more than 1,000 centers for the processing of letters.
With the introduction of the new postal codes in Germany, 83 different district centers were built between 1994 and 1998. In 2003, Briefzentrum 42 (Wuppertal) was closed. Since then, there are only 82 district processing centers.
The processing centers are organized by size, which is determined by the number of letters processed daily:
