Launch of New One-Stop Portal for House and Unit Number and Street and Building Name Applications
The Inland Revenue Authority of Singapore (IRAS) and Street and Building Names Board (SBNB) are pleased to announce the launch of the Property Name and Address digital service on 26 Apr 2023. This new digital service aims to provide greater convenience for users to apply for house and unit number and street and building names on the same platform. You may read the announcement on the Property Name and Address website.
Role of IRAS in House and Unit Number Allotment
The Inland Revenue Authority of Singapore (IRAS) has the authority to allocate and amend house and unit numbers of any property under the Property Tax Act.
Importance of Proper Numbering and Unique Addresses
Houses and buildings are numbered to aid identification. Property developers, owners, or representatives must obtain IRAS’ authorization for the use of unique property addresses and display every house and unit number at a conspicuous location. The use of an unauthorized number is an offence under the Property Tax Act.
Guidelines for House and Unit Numbering
[House Number] [Street Name] [# Unit Number, if any] Singapore [Postal Code]
A suitable house/unit number should:
- Be relevant to the street where the main entrance/frontage is located
- Follow current building and street sequence
- Prevent confusion with other buildings or units in other parts of Singapore
