Singapore’s Postal Code and District Directory 2026

Quick answer: Singapore has 28 postal districts commonly used in property searches and market reporting. To identify a district, take the first two digits of the six-digit postal code and match that postal sector to the table below. For example, a postal code beginning with 47 falls in District 16, while one beginning with 26 falls in District 10.

Property listings in Singapore often begin with a district label such as D9, D10, D15 or D19. It is a useful shortcut for narrowing a search, but it is not the whole location story. One district can contain several neighbourhoods, while nearby streets can sit in different postal sectors.

This guide shows you how to decode the number, identify the areas each district broadly covers and continue to current AI Property listings for that part of Singapore.

How Singapore district codes work

Every Singapore address has a six-digit postal code. For a street address, the first two digits identify the postal sector. Property platforms and market reports then group those postal sectors into the familiar D1-D28 property districts.

The district number comes from the first two digits, not the final four digits. A postal code beginning with 47 maps to D16. A postal code beginning with 52 maps to D18. A postal code beginning with 68 maps to D23.

The full district and sector reference

Use the first two digits of the postal code to find the matching row. The locations are broad orientation labels, not exhaustive street lists.

Source note: Postal-sector logic is based on SingPost's six-digit postal-code system. District-area names follow the property-market convention used across AI Property's district pages.

(Districts are numbered roughly in the order they were gazetted, not geographically, which is why D01 sits downtown but D06 is a small standalone sector wedged between D01 and D07.)

Postal district, planning area and market region are different

Singapore property content commonly uses three location systems. They answer different questions and their boundaries do not always align.

Do not infer a planning-area boundary from a district code. When a purchase decision depends on a precise boundary, school distance or planning designation, verify the full address against the relevant official source.

Why district codes matter to property buyers

A district code gives buyers a fast first filter. It helps organise listings, compare launches in broadly similar locations and understand the shorthand used in market commentary. It is especially useful when you are still deciding which part of Singapore fits your budget and commute.

But the district label is not a valuation. Two homes in the same district can have very different prices because of tenure, age, developer, MRT distance, school proximity, views, unit efficiency and the specific street. A property just across a district boundary does not automatically become a better or worse buy.

Three district-code mistakes to avoid

1. Assuming the sectors always run in sequence.

D17 includes sectors 49, 50 and 81, while D19 includes 53, 54, 55 and 82. Use the table instead of guessing from the number pattern.

2. Treating the district as an exact neighbourhood boundary.

A district can cover several neighbourhoods, and a nearby road can cross a postal-sector boundary. Confirm the full postal code when the exact district matters.

3. Assuming the district changes tax treatment.

ABSD does not change because a property sits in D10, D15 or D25. The applicable rate depends on the buyer's profile and property count. See AI Property's ABSD rates and remission guide for the current framework.

How to use this when you're comparing new launches

Once you know the district, move from the broad label to the specific project. Compare the following before you shortlist a home:

• Exact address, MRT distance and daily travel time
• Tenure, project age, unit layout and maintenance costs
• Recent transactions for the project and genuine nearby comparables
• School distance measured from the exact address
• Current launch supply and future development around the site
• Total cash, CPF and financing required for the purchase

The bottom line

Take the first two digits of a Singapore postal code and match them to the lookup table. That gives you the property district. Use the district to narrow your search, then evaluate the actual project, address, tenure, transport, affordability and recent transactions before deciding.

Common questions about Singapore district codes

How do I find a district from a Singapore postal code?

Take the first two digits of the six-digit postal code. Those digits identify the postal sector. Match that sector to the D1-D28 table above.

How many property districts are there in Singapore?

Singapore has 28 postal districts commonly used by the real estate industry.

Is District 10 the same as postal sector 10?

No. District 10 contains postal sectors 24, 25, 26 and 27. Postal sector 10 belongs to District 4.

Are postal districts the same as URA planning areas?

No. Postal districts, URA planning areas and the CCR/RCR/OCR market regions are different classification systems, and their boundaries do not necessarily align.

Does a higher district number mean a property is farther from the city?

Not consistently. District numbers are classification labels, not a distance ranking. Check the actual address and travel time.

Can two nearby properties be in different districts?

Yes. A postal-sector boundary can run between nearby streets. Always check the full postal code when the exact district matters.

Winnie's take
A district code is a useful first filter, not a buying verdict. I use it to organise the search, then move quickly to the details that actually affect value: the precise address, tenure, transport, layout, comparable transactions and the price you pay.
