The Cologne city area is divided into 45 postcode areas. This spatial division into the five-digit system was introduced in 1993 by the German Federal Post Office and is almost unchanged in the Cologne city area. The boundaries of the areas are roughly aligned with the district boundaries and, with few exceptions, for example in Finkenberg and Sülz, are contiguous areas.
