# Postal Code Singapore: Look Up Any Address, District and Nearest MRT

Look up any Singapore postal code or address: block, street, building, coordinates, postal district and nearest MRT, using OneMap's official address data.

Interactive tool: https://lookup.sg/tools/postal-code-lookup

## How this works
Searches go to OneMap, the Singapore Land Authority's official map service, which returns the block number, street, building name, postal code and coordinates for addresses, buildings and postal codes. Type all 6 digits of a postal code and it looks up straight away; for an address or building name, press Look up.

Singapore postal codes have 6 digits. The first 2 digits are the postal sector, and sectors are grouped into 28 postal districts (URA's list, sourced from SingPost). District 09, for example, is sectors 22 and 23: Orchard, Cairnhill and River Valley. Property listings and URA transaction data still use these districts.

The nearest MRT and LRT stations are measured in a straight line from the address to each station, so treat the walking time (at 80 m a minute) as a lower bound. For schools, hawker centres, clinics and more around an address, open its neighbourhood report.

## FAQs
### How many digits is a Singapore postal code?
6. The first 2 digits are the postal sector, which tells you the postal district: 52 is District 18 (Tampines, Pasir Ris), 23 is District 09 (Orchard) and 01 to 06 are District 01 (Raffles Place, Marina).

### Which postal district is my postal code in?
Take the first 2 digits and find them in the district table. For example 310177 starts with 31, which is District 12 (Balestier, Toa Payoh, Serangoon), and 529510 starts with 52, which is District 18.

### What is District 10 in Singapore?
District 10 covers postal sectors 24, 25, 26 and 27: Ardmore, Bukit Timah, Holland Road and Tanglin. URA's Core Central Region is Districts 09, 10 and 11 plus the Downtown Core and Sentosa.

### How do I find the postal code of an address?
Type the block and street (e.g. 177 Toa Payoh Central) or a building name (e.g. ION Orchard) and press Look up. OneMap returns the matching addresses with their postal codes: ION Orchard is 238801.
