Postal codes in Singapore have consisted of six digits since 1995, replacing the four-digit system introduced in 1979. They are administered by Singapore Post. 

In Singapore, zip codes are referred to as postal codes and are an essential part of the country's efficient mail delivery system. Postal codes are numerical codes assigned to specific geographic areas by Singapore Post Limited, the national postal service provider.

Singapore's postal codes consist of six digits and are structured to provide a high level of precision in addressing. The first two digits represent the sector, which corresponds to a particular district or region within Singapore. The next two digits further narrow down the location to a smaller planning area or neighborhood. The final two digits help pinpoint a specific street or building within that area.

These postal codes are crucial for ensuring accurate and timely delivery of mail and parcels. By incorporating the postal code in their addresses, individuals and businesses can help ensure that their mail reaches the intended recipients efficiently. Postal workers rely on these codes to sort and route mail to the appropriate delivery routes, saving time and reducing the chance of misdeliveries.

Singapore's postal code system is designed to support the island's urban planning and infrastructure development. The sector and planning area components of the postal code reflect the country's town planning regions and provide a systematic method for organizing addresses. This allows for efficient management of mail distribution, as well as enabling effective allocation of resources and services within each planning area.

Postal codes in Singapore are not only used for mail delivery but also have broader applications. They are widely utilized in various sectors, including logistics, e-commerce, and online mapping services. Businesses leverage postal codes for accurate address verification, efficient routing of deliveries, and targeted marketing campaigns. Online platforms and navigation systems rely on postal codes to provide accurate location-based services, such as locating nearby services, calculating distances, and providing precise directions.

Singapore's postal code system also supports demographic analysis and planning initiatives. Government agencies, researchers, and analysts utilize postal code data to gather insights into population distribution, housing patterns, and socio-economic indicators. This information aids in policy development, urban planning, and resource allocation.

In conclusion, Singapore's postal codes are an integral part of the country's mail delivery infrastructure and serve a crucial role in ensuring accurate and efficient delivery. With their detailed and structured format, postal codes enable precise addressing, support urban planning, and facilitate various industries and services. By incorporating postal codes into addresses, individuals and businesses contribute to the smooth functioning of Singapore's postal system and benefit from streamlined mail delivery and location-based services.

In 1950, Singapore was initially divided into 28 postal districts, each of which was given a number. For instance, District 9 included the Orchard Road region.

Singapore 9

In 1979, a new four-digit system was introduced, with the final two numbers designating a sector in each district. There were 81 sections altogether.

277 Orchard Road

Singapore 0923

This was changed to a six-digit system on September 1, 1995. Each building was assigned a unique postcode under this system, with the first two digits standing in for the previous sector,  i.e. 23.
