Singapore uses a 6-digit numeric postal code system to identify buildings and delivery locations across the country. Each postal code is assigned at the building or property level, making mail delivery highly precise. The first two digits generally indicate the postal sector, which aligns closely with Singapore’s planning areas and regions.
Postal codes in Singapore are managed under the national postal system and are widely used for mail delivery, logistics, government services, and address verification.

About Singapore Postal Codes
Singapore uses a six-digit postal code system to ensure accurate mail and parcel delivery throughout the city-state. Each postal code corresponds to a specific building, street, or area, with the first two digits representing the sector or planning district. This system covers all regions — Central, East, North, North-East, and West and is managed by Singapore Post (SingPost). Even for areas without an assigned code, nearby postal codes are typically used for addressing.
