Tanzania ZIP Codes

Tanzania uses a “Postal codes” system, which is a five-digit numeric format, like 99999, with no letters or separators. This means it uses only numbers. According to the GeoPostcodes world postal code database, Tanzania has 4,225 postal codes covering 4,539 regions and 21,942 towns. This format is similar to US ZIP codes, which are also five digits and purely numeric.

Tanzania ZIP & Administrative boundaries

Tanzania 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.

Tanzania Administrative Divisions

GeoPostcodes provides a standardized reference for Tanzania’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.
