Postal district finder: which district is a postal code in

How postal districts work

A Singapore postal code has six digits, like 238123. The first two are the postal sector (23), and the last four are the delivery point in that sector. Each sector belongs to one of 28 postal districts, the “D09” and “D15” in property listings:

Take the first two digits of the postal code: 238123 → 23.

Find that sector in the table below: 23 is in District 09, Orchard, Cairnhill, River Valley.

The sectors aren’t in district order: sector 09 is in District 04, and 81 (Changi) is in District 17.

District	Sectors	General location
D01	01, 02, 03, 04, 05, 06	Raffles Place, Cecil, Marina, People’s Park
D02	07, 08	Anson, Tanjong Pagar
D03	14, 15, 16	Queenstown, Tiong Bahru

D19	53, 54, 55, 82	Serangoon Garden, Hougang, Punggol
D20	56, 57	Bishan, Ang Mo Kio
D21	58, 59	Upper Bukit Timah, Clementi Park, Ulu Pandan
D22	60, 61, 62, 63, 64	Jurong
D23	65, 66, 67, 68	Hillview, Dairy Farm, Bukit Panjang, Choa Chu Kang
D24	69, 70, 71	Lim Chu Kang, Tengah
D25	72, 73	Kranji, Woodgrove
D26	77, 78	Upper Thomson, Springleaf
D27	75, 76	Yishun, Sembawang
D28	79, 80	Seletar

So postal codes start with 01 to 82, but never 74: no district has that sector, or 00, or 83 and up.

Questions

Why do property listings say D10 or D15?

Property listings and URA’s property statistics group homes by postal district. URA’s Core Central Region, for example, is postal districts 9, 10 and 11 plus the Downtown Core and Sentosa (URA on data.gov.sg).

Are the place names the district’s boundaries?

No. They’re URA’s general locations, a rough guide to what each district covers. Only the first two digits of the postal code decide the district.

Is a postal district the same as a planning area or an HDB town?

No. Postal districts are groups of SingPost’s postal sectors. URA’s planning areas and HDB’s towns are other ways of dividing up Singapore, with their own boundaries, so a place can share a name without sharing the ground.

Does a district mean the postal code exists?

No: the district comes from the first two digits only. To find the address for a full postal code, look it up on SingPost or OneMap.

Is the postal code I type sent anywhere?

No. A postal code can point to someone’s home, so it’s worked out in your browser: it isn’t sent to us or anyone else, and it never goes into the page’s address.
