Choose new, change or withdrawal after planning approval
The 26 April 2023 guide covers all five application modules. Layout changes from new erection, redevelopment, addition/alteration or demolition require a building-identification application. Obtain the relevant Written Permission/Planning Clearance and approved plans before applying; Planning Clearance concerns ministry/government projects. New includes private/public development and additional units at existing development; Change includes unit reconfiguration or house renumbering after street/main-entrance change; Withdrawal removes all or selected obsolete numbers. Once allocated, display house/unit numbers conspicuously from road or main entrance under the display guidelines.
Common login, site polygon and URA selection
Use Property Name and Address (PNAA), log in and Add a New Application; one-time setup/account update and two-step verification may be required. Locate using old IRAS address, building name, postcode or land description. Show Land Boundary helps check the polygon; redraw with the drawing tool if wrong, then Confirm Location. New applications retrieve Former Address on Site and URA Development Applications from that polygon. Add More/delete corrects old addresses. Select/Edit Development Application and Confirm the correct URA application; if missing, search its ES Reference ID. Approval of new house/unit numbers withdraws all existing unit numbers assigned to the former address, making accurate old-address selection essential.
New houses and units: generate and verify
Select New House and/or Unit Number and the development type; new private/public development or redevelopment requires the appropriate URA approval. Add House Number with an SBNB-approved street. Choose house numbers only, houses plus units, or new units for existing houses. For a single number such as55 Newton Road enter55 in the first range field and Continuous Numbers, then Generate. For units, Add/Edit New Unit Number, enter storey/unit ranges and URA-approved Use, Generate, add/delete entries or correct uses, then Save. At most2,000 units may be generated; applications exceeding this must be split into parts. Check the automatic house/unit totals, Export if useful and confirm the checkbox; return to Add/Edit to correct.
Change unit numbers after layout reconfiguration
Select Change House and/or Unit Number and locate the site. Answer No to renumbering caused by street or main-entrance change when the issue is splitting, combining, adding units or floor-area changes. Add Existing House Number, approved street and range; a single1 Punggol Drive uses1 and Continuous Numbers. Generate, then Add/Edit Existing Unit Number with storey/unit ranges, continuous/odd/even choice and approved use. The system validates that old units exist in IRAS records. Enter proposed new unit numbers and reasons, add/delete as needed, Save, verify totals and upload plans/documents. The rendered example shows Combine Units; select the actual reason rather than copying the example.
Change a house number after street or entrance change
Use the same Change application but answer Yes to a street/main-entrance change. Add the existing street and house range, Generate and supply the proposed New House Number, New Street Name, Effective Date and Reason for Change. Add/Edit existing affected units with storey/unit ranges, continuous/odd/even and approved use, validate existing records, enter proposed units and Save. Verify automatic totals and confirm. This branch changes the house address and carries affected units; it differs from the layout-only unit branch.
Withdrawal has three different scopes
For removed/demolished buildings or unnecessary units, choose Withdraw House and/or Unit Number. Locate the site and Add House Number/range, using the first range field and Continuous Numbers for a single house. Generate, then choose: withdraw house and all units; withdraw all units while retaining house; or withdraw some units while retaining house and others, such as removing an ATM unit. Enter relevant storey/unit ranges, Generate and Save, resolving invalid IRAS-unit errors. Check totals/Export and confirm the list. Annotate withdrawn numbers on the demolition/removal site plan before upload.
Plan and supporting-document limits for every branch
Site plans must show annotated house numbers and accept PDF only, maximum2 MB. Approved building plans accept PDF up to20 MB; typical-floor and distribution plans where relevant are recommended, with clear boundaries and proposed unit numbers. For supporting approvals such as Temporary Occupation Licence, landowner no-objection or public-block/street details, permitted formats are BMP,DOC,DOCX,GIF,JPG,JPEG,PDF,PNG,PPT,PPTX,TIF,XLS,XLSX with total attachments at most20 MB. The same attachment categories appear in new, unit-change, house-change and withdrawal modules. Clear demarcation and numbering reduce processing delays.
