Singapore Property Districts Explained:
The Complete Guide to D1–D28

Where the D1–D28 System Came From

Singapore's property districts are a legacy of the postal system, not a modern planning framework. In 1950, Singapore introduced a two-digit postal code system dividing the island into 28 geographic sectors for mail sorting. The system was updated to four digits in 1979 and then replaced by the current six-digit postal code in 1995, where each building received its own unique identifier.

Under the six-digit system, the first two digits identify a postal sector, and those sectors map back to one of the original 28 districts. This means the district number is not the same as the first digits of a postal code. District 9, for example, corresponds to postal sectors 22 and 23 — so a property with a postcode beginning in “23” is in District 9, not District 23. That mismatch confuses many buyers who assume the postal code directly reveals the district.

Although districts are no longer the live postal logic, they are deeply embedded in property marketing. Portals like PropertyGuru and SRX still use district filters as a primary search field. URA's own residential transaction search allows postal district lookup. And agents routinely describe properties as “D10 freehold” or “OCR D19” as first-pass signals of location prestige and price tier.

Understanding CCR, RCR and OCR: Singapore's Three Market Zones

Layered on top of the 28-district system is a separate framework that the Urban Redevelopment Authority (URA) uses for official property market statistics. URA divides Singapore's non-landed private residential market into three segments — CCR, RCR, and OCR — which are the categories used to report the Property Price Index (PPI) and official transaction data. Understanding these zones is more important than knowing the district number alone.

Core Central Region (CCR) — Premium

The CCR comprises postal districts 9, 10, and 11, the Downtown Core planning area, and Sentosa. This is Singapore's prime luxury residential market: scarce land, high concentrations of freehold tenure, Orchard Road and CBD proximity, entrenched prestige, and historically strong foreign-buyer demand. Properties here command the highest per-square-foot values in the country and serve as long-term wealth-preservation assets for high-net-worth buyers.

Importantly, the Downtown Core and Sentosa are area-based overlays within the CCR definition — they are not separate district numbers. This is why prime downtown properties in parts of D1, D2, D4, D6, and D7 can be classified as CCR even though those districts are not purely CCR districts.

Rest of Central Region (RCR) — City Fringe

The RCR covers the planning areas within the broader Central Region that fall outside the CCR components. In market terms this is the “city fringe” — districts like Queenstown (D3), Toa Payoh (D12), Marine Parade (D15 coastal), and Bishan (D20). RCR properties offer faster CBD access and stronger gentrification narratives than the outer suburbs, at more moderate entry prices than the prime core.

Outside Central Region (OCR) — Heartlands

The OCR covers all planning areas outside the Central Region — the heartland towns of the north, east, and west. Tampines, Punggol, Jurong, Woodlands, Bedok, Yishun. The OCR accounts for approximately three-quarters of Singapore's total residential land area and is home to the majority of public housing estates, executive condominiums, and mass-market private condominiums. The buyer base is predominantly domestic: HDB upgraders and first-time private home purchasers.

District-by-District Reference Guide: D1 to D28

The table below covers all 28 Singapore property districts. Zone classifications follow URA's official market-segment definitions. Districts marked “CCR / RCR” or “RCR / OCR” straddle boundaries — do not apply a single zone label to the entire district. General positioning is a search-stage shorthand, not a valuation model; project-level and address-level checks are always required.

How Districts Affect Property Prices and Appreciation

Districts 9, 10, and 11 have long been Singapore's residential price benchmarks. The premium is structural, not arbitrary: D9 concentrates Orchard Road and the central luxury belt; D10 holds the Good Class Bungalow enclaves, the Botanic Gardens, and the top-school corridor along Bukit Timah; D11 anchors the medical cluster at HealthCity Novena alongside prime residential estates. All three districts feature scarce new land, high freehold concentrations, and established institutional and foreign-buyer demand. These are wealth-preservation addresses that have maintained premium status across multiple property cycles.

Twenty years of OCR and RCR outperformance

The more counterintuitive finding is that the OCR and RCR have outpaced the CCR in capital growth over the past two decades. Between 2006 and 2026, private condominium prices in the OCR grew approximately 4.07 times, rising from a median of S$519 psf to S$2,111 psf. RCR properties appreciated approximately 4.00 times over the same period. CCR, starting from a higher base, appreciated approximately 2.41 times.

Three structural forces drove OCR outperformance. First, a large domestic HDB upgrader pool provides sustained demand for mass-market private condominiums and Executive Condominiums — demand that is less sensitive to international capital flows and foreign ownership restrictions. Second, URA's decentralisation strategy has shifted significant employment and commercial activity outside the city centre: the Jurong Lake District is planned as Singapore's largest business hub outside the CBD, Punggol Digital District is a technology and innovation cluster, and Woodlands Regional Centre is a major commercial node in the north. Third, successive rounds of Additional Buyer's Stamp Duty increases — particularly the April 2023 rate hike to 60% for foreign buyers — dampened demand in the investor-heavy CCR while leaving the predominantly owner-occupied OCR market relatively insulated.

The CCR-RCR price gap is at a 30-year low

The premium required to buy in the CCR over the RCR has compressed significantly. In 2006, the median CCR-RCR price gap for new non-landed homes was approximately 80%. By 2025 it had narrowed to roughly 10% — the smallest gap since 1995. For mid-sized units of 700 to 1,000 square feet, the absolute quantum premium shrank from approximately S$568,000 in 2020 to approximately S$213,000 in 2025. Competitive Government Land Sales bidding has pushed RCR land costs up, while CCR developers have optimised unit sizes to attract local buyers within tighter borrowing frameworks. In 2H2025, between 60% and 76% of transactions at prime CCR launches like River Green, Skye at Holland, and UpperHouse at Orchard Boulevard were completed under S$2.5 million.

In 1Q2026, URA reported non-landed price growth of 2.2% in OCR, 0.8% in RCR, and 0.6% in CCR — continuing a pattern where suburban and city-fringe demand has been stronger on a growth basis than the prime core in recent quarters. This does not make CCR assets less valuable in absolute terms — they still trade at the highest psf in the market — but it does mean the “CCR expensive, OCR cheap” framing misses the more nuanced picture of where capital growth has actually come from.

Common Mistakes Buyers Make with Districts

Assuming every part of a district is equivalent

District 4 is the most cited example. Sentosa Cove is an ultra-premium CCR resort enclave. Telok Blangah and HarbourFront on the mainland, in the same district, are RCR mid-tier urban locations. A buyer who assumes mainland D4 properties will track Sentosa pricing or carry Sentosa's prestige is likely to be disappointed. The same principle applies to D15: Meyer and Amber Road are premium coastal RCR; Siglap and Frankel are suburban OCR. Both are District 15 — but they are in different market zones with different appreciation drivers.

Not checking the sub-zone and regional boundary

Districts 1, 2, 4, 5, 6, 7, 14, 15, and 20 all straddle market zone boundaries. A buyer shortlisting “D20” needs to know whether the specific project sits in the Bishan portion (which trades closer to RCR city-fringe) or the Ang Mo Kio portion (which is more squarely OCR). The district label does not tell you this — only the address and URA SPACE verification can.

Conflating “central location” with CCR

A property can be geographically central — in Toa Payoh, Queenstown, or Bishan — and still be classified as RCR, not CCR. The Central Region contains both CCR and RCR. A buyer who expects CCR-level capital preservation dynamics from a Toa Payoh HDB upgrade condo is using the wrong framework.

Treating district prestige as more important than address

Once the search is narrowed to a specific project, the district label matters less than project age, tenure (freehold vs. leasehold), street orientation, floor level, school proximity, MRT walking distance, and immediate land use surroundings. A leasehold project on a poor-facing unit in D10 may underperform a well-located freehold project in D20 on a ten-year resale horizon. District is a useful first filter — it should not be the only filter.

How to Use Districts Effectively in Your Property Search

Districts are most useful as a discovery filter — a way to identify a rough geographic area and price tier before drilling down. Most major portals allow district-based search as a primary field, which makes them a practical starting point. But the workflow should shift at the shortlisting stage.

Step 1: Use district as a first-pass filter

Search by district on your preferred portal to generate a longlist of projects in the rough area and price tier you are targeting. Use the CCR/RCR/OCR zone as a parallel filter if the portal supports it — this removes the ambiguity of split districts.

Step 2: Shift from district thinking to address thinking

Once you have shortlisted specific projects, verify each address using URA SPACE, URA's official map-based planning portal. SPACE shows the exact planning area, subzone, zone classification, plot ratio, and surrounding land use for any address. It is the authoritative tool for confirming whether a property is actually in the CCR, RCR, or OCR — regardless of what the district label suggests. OneMap, maintained by the Singapore Land Authority, is the national authoritative map and useful for checking precise geographic boundaries and nearby amenities.

Step 3: Check planning context and long-term outlook

URA's Master Plan — updated every five years — is the statutory land-use plan for Singapore. It governs zoning, allowable plot ratios, and major infrastructure investments on a 10 to 15-year horizon. OCR districts near designated growth nodes (Jurong Lake District, Punggol Digital District, Woodlands Regional Centre) have a fundamentally different long-term outlook than comparable OCR districts without planned investment. The Master Plan is publicly accessible and should be consulted before any significant purchase decision.

One important caveat: URA's official datasets — transaction caveats, planning maps, and statistics — are organised by planning areas and subzones, not by D1–D28 postal districts. When official statistics cite a location, they use planning area names like “Queenstown” or “Novena”, not district numbers. District numbers are a marketing and search convention layered on top of the official planning geography. Both systems are useful — but they are not the same system.

Foreign Buyer Considerations: Districts, CCR and ABSD

Historically, foreign buyer demand in Singapore has concentrated in the prime luxury segment — Districts 9, 10, and 11 — along with the Marina Bay/Downtown Core area and Sentosa Cove. In the period from 2020 to 2022, foreign buyers constituted approximately 60% of Singapore's luxury condominium market. The CCR — with its freehold stock, Orchard Road and CBD proximity, and international brand recognition — has been the natural target for wealth preservation buyers from the region.

ABSD rates as of April 2023

The April 2023 ABSD revision significantly changed the economics for foreign buyers. Rates now apply as follows. This is factual reference only — buyers should seek independent legal and tax advice before transacting.

Standard Buyer's Stamp Duty (BSD) also applies to all buyers, with a top marginal rate of 6% on the portion of value above S$3 million. Nationals of Iceland, Liechtenstein, Norway, Switzerland, and the United States may be eligible for Singapore-citizen-equivalent ABSD treatment under applicable Free Trade Agreements, subject to conditions. Verify with IRAS or a qualified tax professional.

ABSD rates do not vary by district

Whether a foreign buyer purchases in D9 or D19 makes no difference to their ABSD liability. The rate is determined entirely by the buyer's residency status, nationality, and number of residential properties owned — not by location. What districts affect is where foreign demand has historically concentrated, which has been the prime core. The 60% ABSD rate introduced in April 2023 was a significant factor behind the relative softening of foreign-buyer demand in the CCR market since then.

Landed property restrictions and Sentosa Cove

Under the Residential Property Act, foreign nationals — including Permanent Residents — generally cannot purchase landed residential properties on mainland Singapore without approval from the Land Dealings Approval Unit (LDAU) of the Singapore Land Authority. Approval criteria are stringent: typically requiring at least five years of Permanent Residency and a demonstrable track record of economic contribution.

Sentosa Cove (within District 4) is a partial exception. Foreign nationals may apply to purchase landed homes there without needing to meet the mainland landed criteria. However, approval is still required. The landed properties in Sentosa Cove are 99-year leasehold, must be strictly owner-occupied (they cannot be rented out), the land area cannot exceed 1,800 square metres, and each approved buyer may hold only one such property at a time. Foreign buyers may purchase Sentosa Cove condominium units without LDAU approval — only landed homes require it.
