Effective March 1: Vietnam's property identification-number system explained

From March 1, 2026, every real-estate asset will be assigned a unique electronic identification number. So what do you need to know about the property-ID system taking effect on March 1?

On December 31, 2025, the Government of Vietnam issued Decree No. 357/2025/ND-CP on the development and management of the housing and real-estate market information system and database. The decree takes effect on March 1, 2026.

Under this decree, a real-estate electronic ID number (covering housing and the exclusive-use area inside a building) is a code of up to 40 alphanumeric characters, assigned individually to each home (apartment or detached house) or to a piece of real estate inside a building. The information is integrated and managed in the housing and real-estate information system and database.
