Our location dataset for Oman

Explore our comprehensive collection of Oman ZIP code and administrative data products, designed to meet all your mapping and location intelligence needs.

Oman ZIP Codes

Oman uses a “Postal code” 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 Oman’s three. According to the GeoPostcodes world postal code database, Oman has 101 postal codes covering 72 regions and 3,946 towns.

Oman ZIP & Administrative boundaries

Oman 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.

Oman Administrative Divisions

GeoPostcodes provides a standardized reference for Oman’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.
