Our location dataset for Iceland

Iceland ZIP Codes

Iceland uses a “Póstnúmer” system, which is a three-digit numeric format, like 999, with no letters or separators. This means it uses only numbers, unlike US ZIP codes which are also numeric. However, US ZIP codes are five digits long compared to Iceland’s three. According to the GeoPostcodes world postal code database, Iceland has 193 postal codes covering 72 regions and 108 towns.

Iceland ZIP & Administrative boundaries

Iceland administrative landscape often follows inconsistent regional models and irregular public sources, making it difficult to maintain reliable boundaries. Our standardized postal and administrative boundary data resolves these gaps to ensure complete, coherent geographic coverage.

Iceland Administrative Divisions

GeoPostcodes provides a standardized reference for Iceland’s address structure, ensuring consistent, accurate, and globally aligned formatting across your systems. The dataset captures the official address elements required by the national postal operator and maps them into our unified global schema.
