Under a joint plan of the Ministry of Agriculture and Environment and the Ministry of Public Security, a 90-day campaign has been launched nationwide to enrich and cleanse the national land database. 

The campaign will be implemented over 90 days, from September 1 2to November 30, 2025.

During the campaign.  a review and cleansing of the entire land database that has been built over various periods at 2,342/3,321 commune-level units will be conducted; while data for Certificates (of residential land and assets attached to the land), that have been issued but have not yet been collected foa a database, will be collected and digitized for created databases.

The campaign will focus on completing the existing land database to ensure it is "accurate - complete - clean - live." This includes developing technical guidance documents and professional procedures for collecting, updating, adjusting, and supplementing land database information, and implementing the two-level local government model; reviewing and classifying land data that has been built up to now (approximately 49.7 million land plots at 2,342/3,321 commune-level units) into 3 groups. "Group 1" includes land plots in localities where a database has been built, the data is being used, and it ensures "accurate - complete - clean - live." "Group 2" consists of localities where a database has been built, but the data needs to be corrected, completed, supplemented, and the information of land users and owners of assets attached to the land needs to be verified. Meanwhile, localities where a database has been built, but the data cannot be used and needs to be rebuilt belong to "Group 3".

In addition,  information of land users and homeowners in the existing database will be verified and integrated to the national population database.
