This was superseded by a new four-digit system on 1 July 1979, with the last two digits representing a sector in each district. There were in total 81 sectors.

277 Orchard Road
Singapore 0923

On 1 September 1995, this was replaced by a six-digit system, in which every building was given its unique postcode, the first two digits of which represented the old sector, i.e. 23.

Although the old districts are no longer used by Singapore Post, they are still widely used to refer to locations of properties for sale or rent.

6-digit postal code

The 6-digit postal code is made up of the sector code and the delivery point. The sector is represented by the first two numbers of the postal code. The remaining four numbers define the delivery point within the sector. e.g.

53 Ang Mo Kio Avenue 3
Singapore 569933

56 is the sector code; 9933 is the delivery point, i.e. house or building. For

(HDB) residential blocks, the block number is included in the postal code. e.g.

Blk 145 Lorong 2 Toa Payoh
Singapore 310145

HDB residential blocks with the same number in the same postal sector are differentiated by their postal codes as follows:

Blk 147 Simei Street 2
Singapore 520147

Blk 147 Tampines Avenue 5
Singapore 521147

Similarly, for a HDB residential block sharing the same number as another block in the same postal sector, but have an added suffix behind are differentiated by their postal codes as follows:

Blk 150 Bishan Street 11
Singapore 570150

Blk 150A Bishan Street 11
Singapore 571150

The postal codes for private residential, commercial and industrial houses and buildings are assigned based on the alphabetical sequence of the street names in each sector. This means that the codes for a particular postal sector have been assigned first to houses and buildings located along street names beginning with 'A', followed by 'B' and so on. The postal codes for such properties do not contain the corresponding house or building numbers included in the postal code. HDB industrial and commercial blocks also use this system.Archive of Old SingPost Website in the Way Back Machine
