About SGPostalCode.com

SGPostalCode.com is a free, comprehensive online directory for Singapore postal codes. We provide instant lookup of any of Singapore's 121,000+ unique postal codes, covering over 141,000 buildings, estates, MRT stations, government buildings, shopping malls, schools, hospitals, and more.

Our goal is simple: help residents, businesses, delivery services, tourists, and developers quickly find the correct 6-digit Singapore postal code for any address — or find the address behind any postal code.

Our postal code database is sourced from Singapore's official building address records and is updated regularly to reflect new developments, building renames, and address changes. The dataset covers the entire island of Singapore, including:

• HDB public housing blocks and estates
• Private condominiums and apartments
• Commercial buildings, offices, and shopping malls
• Government buildings, ministries, and statutory boards
• MRT, LRT, and bus interchange stations
• Schools, polytechnics, universities, and educational institutions
• Hospitals, polyclinics, and healthcare facilities
• Hotels, serviced apartments, and hospitality venues
• Industrial parks, warehouses, and logistics hubs

Singapore uses a 6-digit postal code system introduced by SingPost in 1995. Unlike postal codes in many other countries that cover wide areas, Singapore's postal codes are highly specific — typically pointing to a single building or a small cluster of buildings.

The first two digits of a Singapore postal code indicate the postal sector, which corresponds to a general geographic area. For example, postal codes beginning with 01–08 cover the City and Central Business District, while codes starting with 75–81 cover the Punggol and Sengkang North areas.

Singapore has 83 postal sectors covering the entire island. Postal codes are widely used in delivery logistics, e-commerce, government forms, property listings, and navigation apps.
