The regulation was introduced in Decree No. 357/2025/ND-CP, recently promulgated by the government, on the construction and management of information systems and databases for housing and the real estate market.

According to the decree, the real estate information system and database will be centrally built and managed, ensuring nationwide consistency from central to local levels. Its purpose is to enhance transparency, synchronization, and efficiency in state management.

Under Clause 5, Article 3 of the decree, the electronic identification code for real estate products - including houses and floor space within constructed facilities - is a string of up to 40 alphanumeric characters. Each property unit, whether an apartment, detached home, or part of a construction project, will be assigned a unique code in the system.

For residential properties, the digital ID is generated based on core information groups: land parcel ID, project or construction code, location code (if applicable), and a natural sequence of characters.

These IDs are automatically generated within the centralized housing and real estate database system. Local Departments of Construction will attach the IDs to properties within housing development projects at the time they issue a notice confirming the property’s eligibility for sale, especially for future-completed housing.

For floor space within a constructed facility, the ID is also composed of similar data sets, including land parcel identifiers, project or construction codes, location codes (if applicable), and a character string.

This type of ID will be automatically created and linked to the floor space when the Department of Construction issues the feasibility study appraisal report for investment in construction.

In addition, digital IDs will also be issued to other entities involved in real estate activities, including condominium management units, licensed real estate brokers, and individuals receiving housing support under social programs.

How the information will be accessed and used

The Ministry of Construction will oversee the national-scale development, operation, and use of the housing and real estate database system.

Provincial People's Committees will be responsible for collecting, updating, managing, and exploiting the data within their jurisdictions.

Organizations and individuals involved in the real estate sector will be granted tiered access rights to create, update, share, and retrieve information as authorized by the relevant state agencies.

The system is designed to be open and compatible with national data architecture standards. It will comply with database protocols, APIs, and decentralized access models, meeting national security and confidentiality requirements.

Data integration with national and sectoral databases is also ensured. Once information is shared across connected databases, there is no need to recollect it.

All data in this system is considered state property, managed by the Ministry of Construction. It is safeguarded to ensure national information security, state secrecy, and personal data protection. Publicly disclosed information on the system's portal will be aggregate data only.

There will be three official methods of accessing housing and real estate market data:

Directly through the system’s information portal
Via online integration between information systems
Through formal written requests submitted to competent authorities

Data sharing among state agencies will be free of charge unless otherwise regulated by law.

For organizations or individuals requiring detailed or specialized data, a request form must be submitted via the National Public Service Portal or other official channels. Applicable data usage fees will be collected according to pricing regulations.
