Singapore Postcode Lookup
Singapore postcode lookup. Reads the first two digits, the postal sector, and names its postal district (D01-D28) from SingPost's list. Browser-only.

How the SG postcode lookup works
Enter the 6 digits
Type or paste the postcode. Spaces, hyphens and a leading "S" (as in S238888) are removed first, so "238 888" works as well as "238888".
Read the sector
The first 2 digits are the postal sector. SingPost's list of postal districts has 81 of them: every number from 01 to 82 except 74.
Get the district
The tool shows the postal district (D01–D28) and the general location SingPost's list gives for it. It does not name a planning area or a region, because one sector can hold addresses in several.
Browse all 28 districts
Below the search, every district is listed with its sectors and general location, in the order SingPost prints them.
About Singapore's 6-digit postcode system
Singapore's six-digit postcode dates from 1 September 1995. The first two digits are the postal sector, carried over from the four-digit codes of 1979; the last four are the delivery point, the number for one house, building or block of flats. Sectors group into 28 postal districts, a division that goes back to the two-digit codes Singapore adopted in 1950.
Districts are not planning areas
The 28 postal districts come from SingPost. The 55 planning areas and five regions come from URA's Master Plan, and the two maps were drawn separately. When we compared a sector-by-sector table of planning areas with 1,140 real postcodes in 77 sectors, it named the right planning area for 70% of them and the right region for 84%. Sectors 44, 53, 57 and 58 each held addresses in more than one region. Postcode 560104, a block on Ang Mo Kio Street 11, is in URA's North-East Region, although this tool used to label every sector-56 code Central. So it now stops at the district.
"Two digits place an address in one of 28 postal districts. They cannot place it in a planning area: the two maps were drawn separately."
Where districts still matter
Property listings use districts as shorthand, and URA uses them officially in one place: its Core Central Region for private housing is postal districts 9, 10 and 11 plus the Downtown Core planning area and Sentosa. Districts 1 and 2 cover the CBD (Raffles Place, Cecil, Marina, Anson and Tanjong Pagar). District 3 is Queenstown and Tiong Bahru, and District 4 is Telok Blangah and Harbourfront. Primary 1 registration does not use districts at all: MOE's priority rests on citizenship and the distance between home and school.
Privacy stance
This tool runs entirely in your browser. Your postcode is never uploaded, logged or transmitted, and the page calls no address service. It reads only the sector, which is enough to name the district but not the building. For a building-level answer there are two places to go. SingPost sells its address data: HDB's own list of blocks leaves the postcodes out and refers users to SingPost, noting that charges may be involved. SLA's OneMap searches addresses at no charge on onemap.gov.sg, and its search API now asks developers to register for a token. This page deliberately calls neither.
Data and sources
Sector-to-district table: SingPost, List of Postal Districts. History: NLB Infopedia, Six-digit postal code system, and SingPost's 160 milestones. The planning-area comparison and the example postcodes on this page contain information from the Master Plan 2025 Planning Area Boundary (No Sea) accessed on 29 September 2026 from data.gov.sg, and from OneMap accessed on 29 September 2026 from onemap.gov.sg, which are made available under the terms of the Singapore Open Data Licence version 1.0.
Two digits from 1979, a block number at the end, and no sector 74
The six-digit code started on 1 September 1995. Under the four-digit code it replaced, 48% of mail had to be sorted by hand (NLB Infopedia).
Each delivery point (a house, a building or a block of flats) has its own code. A condominium with several blocks carries one code per block.
The first 2 digits are one of 81 postal sectors: every number from 01 to 82 except 74, per SingPost's list.
The 28 postal districts are older than the postcode itself: they come from Singapore's first, two-digit postal codes of 1950.
URA's Core Central Region is districts 9, 10 and 11 plus Downtown Core and Sentosa, the one official definition built on postal districts.
Sectors run out of order: 81 belongs to Changi (D17) and 82 to Punggol (D19), and District 26 takes 77–78 while District 27 takes 75–76.
District 1 takes six sectors (01–06), more than any other district.
For an HDB block, the last three digits were the block number in 400 of the 404 blocks we sampled: Blk 208 Toa Payoh North is 310208. This is our observation, not a published rule.
Primary 1 priority goes by distance from the home address (within 1 km, then 1–2 km), which is a building-level question, not a district one.
How many sectors did 1979 start with? NLB says 80 and SingPost's own history page says 81. Today's list has 81.
Frequently asked questions
No. The lookup runs entirely in your browser. Your postcode is never uploaded, logged or transmitted, and the page calls no address service.
No. It reads only the postal sector (the first 2 digits) and names the postal district. For a full address, SLA's OneMap searches addresses at no charge on onemap.gov.sg, and SingPost sells its address data; this page calls neither.
Because the sector cannot tell you. Postal districts come from SingPost, and planning areas and regions from URA's Master Plan; the maps were drawn separately. Tested on 1,140 real postcodes, a sector-level guess got the planning area right 70% of the time and the region 84%, and some sectors hold addresses in more than one region.
Habit, mostly, and one official use: URA defines its Core Central Region as districts 9, 10 and 11 plus Downtown Core and Sentosa. Districts 1 and 2 are the CBD; District 3 is Queenstown and Tiong Bahru, and District 4 is Telok Blangah and Harbourfront.
Yes. According to NLB, the six-digit code kept the last two digits of the old four-digit code as its sector and added four digits for the delivery point.
SingPost's list assigns every sector from 01 to 82 except 74, and none above 82. We found no source that explains the gap, so the tool says 74 is not in the list rather than guess.
No, only the format. The tool confirms that the sector is on SingPost's list. It does not check that a specific 6-digit code has been issued.
SingPost's current list has 81, and every one in this tool matches it (checked on 29 September 2026). For 1979 the sources disagree: NLB's Infopedia says the four-digit system had 80 sectors, and SingPost's own history page says 81. We have not found a source that settles it or dates sectors 81 and 82.
No. Singapore phone numbers have no area codes. See the asean-phone-number-validator tool.
The table is the one SingPost publishes in its List of Postal Districts, on file.go.gov.sg. That document carries no licence statement, so check with SingPost before reusing it commercially.
Method & sources
How it computes
The first two digits of a six-digit postcode are the postal sector; each of the 81 sectors (01-82 except 74) maps to one of 28 postal districts per SingPost's List of Postal Districts. No planning area or region is derived: a sector can span several, so the page names the district only.
What this tool implements
- SingPost's List of Postal Districts assigns every sector from 01 to 82 except 74; District 1 takes six (01-06), more than any other.
- Sectors run out of order: 81 belongs to Changi (D17) and 82 to Punggol (D19). All 81 sectors in the tool were checked against the table on 29 Sep 2026, and a kernel test holds every one.
- A sector names the district, not the building, planning area or region. Checked against 1,140 real postcodes and URA's Master Plan 2025 boundaries, a sector-level planning area was right for 70% and a region for 84%, so neither is shown.
