Singapore uses a numeric code of 6 digits (e.g. 018906). Because leading zeros are significant, codes are always stored as strings — a code such as 018906 is not the same as 18906. Six-digit numeric postal code; leading zeros are significant.

This database currently holds 121,360 postal codes ranging from 018906 to 918146, linked to 141,687 building and address records. Because a single postal code can cover more than one locality or delivery point, the lookup below groups addresses by code and lets you drill into the individual records.

Postal codes matter well beyond mail delivery. Couriers, e-commerce checkout forms and address autocomplete tools rely on the postal code to route a parcel and to verify that the stated address matches the code. This country does not use administrative subdivisions to organise its postal codes. When you look up a code here, treat the associated name as a reference point rather than a full postal address — always confirm the street and house number with the sender or recipient before shipping.

Frequently Asked Questions

Singapore uses a numeric code of 6 digits (e.g. 018906). Because leading zeros are significant, codes are always stored as strings — a code such as 018906 is not the same as 18906. Six-digit numeric postal code; leading zeros are significant.
Yes. Singapore postal codes are a plain numeric string, so a leading zero is part of the code itself. A code beginning with 0 must be written and stored with that zero — it is not the same as the same digits without it.
