History of postal codes in Singapore

Singapore’s very first postal code system was introduced in the 1950s, and was made up of just two digits. It divided the country into 28 districts, and most mail was hand-sorted.

In 1979, a four-digit system replaced the two-digit one, further dividing the 28 districts into 80 postal sectors. At that time, almost half of Singapore’s mail was still being sorted by hand. As the volume of mail was increasing by 6% every year, there was a need to automate the process to cope with the increasing volumes.

In 1995, Singapore Post (Singpost) introduced the six-digit postal code system that we still use today. This new system reduced manual sorting by 17%. The four-digit system was only able to cover 10,000 delivery points, but the new six-digit system allowed for one million unique numbers.

The six-digit code in use today consists of two parts. The first two digits are the sector codes, taken from the last two digits of the old four-digit code. The four subsequent digits represent a specific delivery point within that particular sector. The delivery points within a sector can be either HDB housing blocks, or private housing and commercial buildings. If it is a HDB block, the delivery point will use the block’s number. Private houses and commercial buildings are assigned numbers according to the alphabetical orders of the streets they are on.
