WahLiao reference desk · Researched guide · Sources checked 29 September 2026. This is an explanation of location labels, not a property valuation, investment recommendation or first-hand neighbourhood review.
Singapore districts D1 to D28 are the postal-district labels commonly used in property searches. Find an address’s six-digit postal code, take its first two digits as the postal sector, and use the concordance below to find the district. Do not assume that sector 19 means District 19: sector 19 maps to D7.
The more important distinction is what the number cannot tell you. A postal district is not a planning area, an HDB town, a school-admission guarantee or a valuation. URA’s Core Central Region, Rest of Central Region and Outside Central Region are a separate geographical classification. A district can overlap more than one market segment; assigning every district one region can therefore mislead.
Go to the D1–D28 table, postal-code lookup, CCR, RCR and OCR definitions, comparison checklist or questions and answers. For the wider housing guide, return to The Address.
Which location label answers which question?
| Label | Use it for | Do not use it as |
|---|---|---|
| Six-digit postal code | Identifying the address or delivery point. | A complete description of a neighbourhood. |
| Two-digit postal sector | Looking up the conventional postal district. | The district number itself. |
| Postal district D1–D28 | Understanding a listing filter and broad location references. | A promise about price, quality, schools or commute. |
| Planning area or subzone | Reading planning maps and geographically defined statistics. | An interchangeable name for a postal district. |
| CCR, RCR or OCR | Interpreting the geographical scope of private-property market statistics. | An exact valuation of one home. |
| HDB town or project | Using the geographical categories shown in the relevant public-housing dataset. | A direct substitute for the private-property market segments. |
For the official market-segment definitions, use URA’s property glossary. For an address, amenities and route context, SLA’s OneMap is the national mapping service. A map search and a property listing answer different questions; use both rather than treating either as the whole picture.
Singapore’s 28 postal districts and their sectors
The sectors are the first two digits of the six-digit postal code, including a leading zero. The place names are orientation examples, not surveyed boundaries or a claim that every part of a named road belongs to one district. The table intentionally has no single-region column: use the official market-segment definition for the exact project.

| D1 | 01–06 | Raffles Place; Marina |
| D2 | 07, 08 | Anson; Tanjong Pagar |

Sector concordance cross-checked against the published references from PropertyGuru and PropertyGiant. These are secondary reference tables, not a new government boundary dataset. URA’s official definitions below are the source for market segments. If an unusual postal code is absent from this table, use an address-level lookup instead of forcing it into a nearby number.
How to find your district without confusing it with your sector
Start with the actual building address, not the estate name used in an advertisement. Confirm its postal code in OneMap, keep the first two digits, and find those digits in the table. Preserve leading zeroes when saving postal codes in a spreadsheet: a postal code is an identifier, not a quantity to calculate.
For example, a code beginning 82 maps to D19; 42 maps to D15; 24 maps to D10; and 19 maps to D7. Those examples describe the concordance, not specific property listings. The remaining digits identify a more precise delivery point and are not a second district code.
The sequence is not a measure of prestige or distance. D26 is not automatically farther from your workplace than D20, and D9 is not automatically better for your household than D19. Read the number as a sorting label. Then investigate the actual location.
What do CCR, RCR and OCR mean?
URA defines the Core Central Region as postal districts 9, 10 and 11, together with the Downtown Core Planning Area and Sentosa. The Rest of Central Region is the part of the Central Region outside that set. The Outside Central Region is outside the Central Region. These definitions combine postal-district and planning-area boundaries; they are not simply three consecutive ranges of district numbers. See the REALIS data dictionary and coverage and methodology.
This is why a table that labels all of D5 or all of D20 as RCR is not a reliable project-level lookup. Similarly, Sentosa’s inclusion in CCR does not mean all of D4 is CCR. Downtown Core is a defined planning area, not a casual shorthand for every place an agent calls downtown. Check the actual project against URA’s classification.
A headline about an index for one market segment describes that index and its coverage. It does not establish that every home inside the segment moved by the same percentage. Nor does a private-property index establish the price of an HDB flat. Before applying a number, match the geography, property type, period and measure to the question you are asking.
Why a town name and a district number can both be right
Everyday place names are often broader, narrower or less precise than a statistical boundary. A resident may describe a home by the nearby station, an established estate name or the route they use to reach it. A listing may describe the same home by postal district. A planning document may use a planning area and subzone. That does not make one label fraudulent; it means the labels serve different purposes.
For practical comparison, write down the full address beside every shorthand. A heading such as Bukit Timah is not enough to distinguish D10, D11 and the Upper Bukit Timah references associated with D21. D19 also covers more than one everyday town or estate. The shared label cannot tell you whether two homes have similar routes, surroundings or housing types.
For Punggol’s detailed local context, use The Complete Punggol Guide. For the historical development of a place, begin with The Memory. This page explains the map’s labels; it does not replace those local and historical guides.
A better way to compare two addresses
Use the district to create a shortlist, then set it aside long enough to compare the homes. Record the exact project, tenure, remaining lease where relevant, floor area, floor level, condition, transaction or asking date, and whether the figure is an asking price or a completed transaction. A comparison that mixes those fields can make a district premium appear where the real difference is the home itself.
| Question | Useful evidence | Weak substitute |
|---|---|---|
| Can the home fit the household? | Floor plan, usable rooms, storage and access needs. | A fashionable district label. |
| Does the daily route work? | Address-to-destination route, walking access and a visit at the relevant time. | A straight-line distance or a guessed MRT journey. |
| Are the prices comparable? | Similar property type, size, tenure, condition and transaction period. | A district average beside one unrelated listing. |
| What is payable beyond the headline? | Applicable duties, fees and ongoing costs, checked for the actual transaction. | Assuming the advertised price is the complete budget. |
| What is the environment like? | Documented visits, official planning context and questions about the specific building. | A claim that every street in the district is quiet. |
These are comparison questions, not a recommendation to buy in a particular district. For transaction-cost explanations, use the existing buyer’s stamp duty and ABSD guide. For resale restrictions, use the HDB minimum occupation period explainer. Check the current official rules before making a commitment; this district table does not calculate eligibility or financing.
Practical decision summary
Use a district number to understand where to look, not what to pay. It is useful when a listing filter is unfamiliar, when you need to translate a postal sector, or when you are comparing the geographical scope of articles. It is insufficient for a valuation, a school decision, a promised commute or a prediction of resale performance.
No district guarantees that an address will hold its value in a downturn. No shared district makes two homes equivalent. A smaller home nearer one person’s workplace may suit that person; a larger home elsewhere may suit another. The correct comparison depends on the household and the specific properties, not an assertion that one district always delivers a better life.
Questions people ask
Is the first part of a postal code the district?
It is the postal sector, which must be mapped to the district. For example, sector 19 is D7, while sector 82 is D19. Use the table rather than reading the sector as a district number.
Can I use a district table to determine CCR, RCR or OCR?
Not reliably for every project. URA’s definitions use planning-area boundaries as well as districts 9, 10 and 11. Confirm the exact project rather than assigning one market segment to every district.
Which district covers Punggol and Sengkang?
D19 is the conventional property-search district associated with Punggol and Sengkang, alongside Hougang and Serangoon Gardens. Confirm the particular address: an estate name is not a substitute for its postal code.
Which district is the most expensive?
That question needs a defined property type, time period and measure: total price, price per square foot, median transaction price or rental cost. This page does not publish a ranking because a number without those definitions would mislead. Use comparable transactions and the relevant official methodology.
Does an address in a named district guarantee school admission?
Do not infer admission from the district label. Check the applicable exercise and address-specific requirements directly through MOE’s home-school distance guidance and the official school-query tools. This article does not reproduce or certify the current registration rules.
Sources, scope and maintenance
Official definitions: URA glossary and REALIS data dictionary. Address lookup: SLA OneMap. Sector concordance: the two secondary reference tables linked immediately below the D1–D28 table. The sources were inspected on 29 September 2026; their original publication and effective dates remain their own. The older URA postal-district table could not be retrieved in this check, so it is not presented as a source newly verified here.
This release replaces unsupported value guarantees and whole-district market-region labels in the unpublished draft. It does not claim surveyed boundaries, completed property visits or access to a transaction database. Recheck the official classification when a source changes or when an exact project needs confirmation.
