Sweden uses a five-digit postal code system known as 'Postnummer', formatted as three digits, a space, and two digits (e.g. 111 22). The system was introduced in 1968 by the Swedish postal administration (Postverket), with codes assigned geographically so that the first digit roughly indicates one of ten large postal zones across the country, generally increasing from south to north and east to west.
Postal codes are administered today by PostNord, Sweden's designated postal operator. Each code is typically shared with a 'postort' (postal locality), which may differ from the actual municipality or parish name. Major cities such as Stockholm, Gothenburg, and Malmö have numerous distinct codes to cover different districts, while sparsely populated areas may share a single code across a wide rural area.
Sweden currently has 10,316 postal codes recorded in the database.
