Our location dataset for Singapore

Singapore ZIP Codes

Singapore uses a “Postal code” system, which is a six-digit numeric format, like 999999, 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 Singapore’s six. According to the GeoPostcodes world postal code database, Singapore has 122,991 postal codes covering 59 regions and 54 towns.

Singapore ZIP & Administrative boundaries

Singapore 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.

Singapore Administrative Divisions

GeoPostcodes provides a standardized reference for Singapore’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.
