## How Singapore postal codes work

Singapore uses a **6-digit postal code system** introduced by SingPost in 1995. The first 2 digits identify the **postal sector** (geographic zone). Unlike many countries where one code covers a wide area, Singapore postal codes are highly specific — typically one building or a small cluster.

Postal sector ranges:
- 01–08: City & CBD (Downtown Core, Marina Bay)
- 09–10: Orchard Road, River Valley
- 11–13: Novena, Toa Payoh, Thomson
- 14–16: Geylang, Eunos, Katong
- 17–19: Loyang, Changi, Tampines (East)
- 20–21: Bishan, Ang Mo Kio (North-East)
- 22–23: Jurong, Buona Vista (West)
- 25–28: Yishun, Sembawang, Woodlands (North)
- 31–33: Bukit Timah, Clementi (West)
- 34–37: Serangoon, Hougang, Punggol (North-East)
- 38–42: Sengkang, Pasir Ris (North-East)
- 43–45: Bukit Merah, Queenstown (Central)
- 46–52: Bedok, Simei (East)
- 53–58: Choa Chu Kang, Bukit Panjang (West)
- 59–67: Jurong West, Boon Lay (West)
- 68–71: Lim Chu Kang, Tengah (North)
