How the SG postcode lookup works
Enter the 6 digits
Singapore postcodes have been 6 digits since 1995. The tool only needs the digits — spaces and dashes are stripped automatically.
Look up the sector
The first 2 digits identify one of 80 numeric sectors. Each sector maps to one of 28 Postal Districts (D01–D28) — the well-known real-estate division.
Resolve the district + region
The tool returns the official District number + name + URA Planning Area + Region (Central / East / West / North / North-East).
Browse all 28 districts
Below the search, all 28 Postal Districts are listed with their sector ranges — useful when checking which sectors belong to which district.
About Singapore's 6-digit postcode system
Singapore introduced its 6-digit postcode in 1995, replacing the older 4-digit system. The first 2 digits are the "Postal Sector" — there are 80 active sectors covering the country. Each sector maps to one of 28 Postal Districts, the famous "D01–D28" division that pervades Singapore real-estate listings, school zone lookups, and HDB applications.
Districts ≠ Planning Areas
The 28 Postal Districts (a SingPost / real-estate concept) are not the same as the 55 URA Planning Areas (the official town-planning units like Bishan, Tampines, Bedok). A postcode resolves cleanly to both — and the planning area is often more useful for census and HDB data.
"D09, D10, D11 — the so-called 'prime districts' — concentrate over 60% of Singapore's freehold properties and command the steepest premiums in the resale market."
Why district matters
For property buyers, "the district" is shorthand for prestige and price band. Districts 1–4 are the CBD/Marina; 9–11 are the traditional prime residential zone (Orchard, Bukit Timah, Newton); 15 and 16 cover East Coast; 19, 28 cover the developing northeast. Postal Districts also feed school enrolment priority, gym chain zoning, and even insurance regional pricing.
Privacy stance
This tool runs entirely in your browser. Your postcode is never uploaded, logged, or transmitted. The lookup is at sector (first 2 digits) level — sufficient for over 95% of use cases. Full building-level resolution requires SingPost's commercial database, which we deliberately do not vendor.
10 facts about Singapore postcodes
Singapore switched from 4-digit to 6-digit postcodes in September 1995 to support full address-level routing.
Every building has its own unique 6-digit postcode — so the postcode pinpoints the building, not just the street.
The first 2 digits (00-82) define one of 80 active Postal Sectors. Codes 74, 76, 79, and 80-99 are mostly unused or industrial.
The 28 Postal Districts (D01-D28) are a real-estate convention used by URA, SLA, banks, and property portals — not strictly an official postal classification.
D09 / D10 / D11 are the traditional "prime districts" — Orchard, Bukit Timah, Newton/Novena.
Postcode 238888 = The Centrepoint on Orchard Road (District 9). Postcode 018989 = Marina Bay Sands.
Singapore has the world's highest postcode density at ~14,000 codes per 100 km² — each building has its own.
HDB block addresses follow predictable postcode patterns within their estate — e.g. all Toa Payoh blocks fall in sectors 31–33.
Postcode-based school priority: living within 1 km of a primary school grants Phase 2C priority — checked using exact 6-digit postcode.
SingPost's commercial postcode database (Postal Code Search Web Service) is paid; this tool ships only the public sector → district mapping.
Frequently asked questions
No. The lookup runs entirely in your browser. Your postcode is never uploaded, logged, or transmitted.
Only to sector (first 2 digits) → District + Planning Area + Region. Building-level lookup requires SingPost's commercial database which we don't vendor.
Postal Districts (D01–D28) are a real-estate / SingPost concept used for property listings. Planning Areas (55 total) are URA's official town-planning units (Bishan, Tampines, etc.) used for census and HDB data.
Because price bands cluster strongly by Postal District. D09–D11 are prime residential; D01–D04 are CBD/Marina; D15–D16 East Coast; D19/D28 the developing northeast.
No. The 1995 switch was a complete renumbering — old 4-digit codes no longer route mail. Some addresses just gained new 6-digit codes; many were reassigned.
They're either reserved, industrial-only (e.g. Jurong Island), or not yet allocated to residential use. The lookup focuses on the active residential and commercial sectors.
Format only. The tool confirms whether the sector is in the SingPost numbering plan — it does not verify that a specific 6-digit code is currently issued.
No — Singapore mobile and landline numbers have no area codes (you have us beat there). See the asean-phone-number-validator tool.
It's the canonical SingPost/URA mapping, stable since 1995. Edge cases (e.g. new sectors at Punggol, Bidadari) are reflected in the sector table.
Yes — the sector → district mapping is public/SingPost gazetted information. The JavaScript table in this tool can be copied into your own code with no licensing concern.
