5 problems in data building

According to Dr. Pham Viet Thuan (Director of the Institute of Resource and Environmental Economics, Ho Chi Minh City), the key is a cross-sectoral data strategy that is interconnected and standardized among management agencies.

To effectively implement real estate identification codes, it requires not only a modern digital system, but more importantly, a cross-sectoral data strategy that is interconnected and standardized across management agencies, from land and tax authorities to land registration offices, communes/wards, and related public services.

1. The foundation of any national data system is the quality of its input data. Currently, real estate data in Vietnam is scattered across multiple systems: cadastral data from the Ministry of Agriculture and Environment , land use rights registration data from registration offices, construction data from the Ministry of Construction, tax data from the Ministry of Finance, and administrative data at the commune/ward level.

Such a fragmented data environment easily leads to noise, duplication, inaccuracies, and contradictions, making any identification system, if not standardized from the outset, merely a number on paper. Therefore, the process of data standardization, from collection, cleaning, standardization to unified storage according to a common standard, is a crucial step.

This needs to be designed and implemented by a highly authoritative inter-sectoral data steering committee, rather than being limited to individual administrative units or sectors.

2. For the identification code to be effective, data interoperability between agencies must be ensured. This code must become the key that allows each agency, from land administration to taxation, planning to banking, etc., to access and update the property status according to their legal authority.

For example, tax authorities need to access data using unique identifiers to collect transfer tax, land use tax, and other related fees, instead of relying on fragmented paper records. Planning agencies must have interconnected data to understand land use planning for each identified parcel.

Land registration offices must directly update transaction events, mortgages, or changes in ownership into the central system so that all information is continuously and accurately reflected.

3. The design of technical systems and operating procedures must prioritize data quality and flexibility. Identifiers should be automatically assigned by the system with clear logic; for example, the land parcel identifier should be the core component, followed by project, construction, and product levels – avoiding manual assignment that could lead to confusion.

The mechanisms for correcting, appealing, and handling data errors must be legalized, transparent, and easily accessible, so that citizens and businesses, upon discovering errors, do not find themselves in a situation where they are "digitized but abandoned."

4. To build trust and promote data sharing, a legal framework is needed to protect personal data and assets. Identification codes are essentially a type of digital identity for real estate; if this system is not secure, the risk of information leakage and misuse for illegal purposes is very high.

Therefore, Vietnam needs to learn from and adopt international standards on data protection, ensuring that every access and sharing of data complies with privacy rights and legal regulations – thereby building trust among citizens and businesses interacting with the system.

5. This policy must be linked to practical applications in public services, banking and finance, proptech (technology in real estate), and transaction processes to demonstrate real benefits.

When the identification code is linked to electronic notarization systems, banks evaluating collateral, or market data platforms, it will help reduce transaction costs, curb speculation and fraud, and promote a more transparent, healthy, and efficient market.

In summary, real estate identification codes are a necessary and correct step in modern market governance. However, to achieve tangible results, a comprehensive strategy is needed for standardized data, technical interoperability, clear processes, and a legal framework, aiming to transform the identification code from a mere number into the central element of the national real estate data infrastructure.

This is the crucial condition for transforming this policy into an effective management tool, creating a foundation for sustainable development of the Vietnamese real estate market in the future.
