On March 5, the Ho Chi Minh City Digital Transformation Center said that the unit is coordinating with departments and branches to build a comprehensive solution to form a city-wide house number database and develop common software to serve the issuance and management of house number records.
This is a step to concretize the direction of the Ho Chi Minh City People's Committee on building software to apply a unified geographic information system (GIS) throughout the city, serving the work of numbering and attaching house numbers.
The Ho Chi Minh City Digital Transformation Center said that in the first quarter of 2026, it will evaluate the application model of GIS technology in house numbering and numbering in An Khanh ward. At the same time, it will expand surveys in some wards with different urban characteristics such as stable residential areas, urban project areas being implemented, sparsely populated residential areas or areas with many agricultural land.
This approach aims to verify the suitability of the model in many practical conditions, from densely populated areas to areas undergoing urbanization.
In parallel with the pilot program, the Ho Chi Minh City Digital Transformation Center will coordinate with departments and branches to collect, compare and standardize data.
In which, cadastral data, land plots and current status maps are compiled from the Ho Chi Minh City Department of Agriculture and Environment; thematic map layers will be integrated and standardized according to the new administrative boundaries.
On that basis, the system will form important data layers such as: ward boundaries, roads - alleys, land plots, construction works and existing house numbers.
After processing, the data will be transferred to each ward and commune for field survey, ensuring accuracy before officially putting it into operation.
The city will also prepare a cost estimate for project implementation, including data construction costs, software development, server infrastructure, field surveys and operational staff training.
On a standardized data platform, a software system for issuing and managing house numbers will be built. The Ho Chi Minh City Department of Construction will coordinate to establish management accounts, decentralize powers at each level from the city to the ward, ensuring centralized management but operating in a decentralized direction.
The software is expected to meet many important functions such as house number management on GIS maps, online new house number issuance, historical retrieval of changes, search by land plot and connection and data sharing via application programming interface (API) in real time. The system also ensures information security requirements and is ready to integrate with other digital platforms for departments and sectors to exploit.
Ho Chi Minh City People's Committee will issue operating regulations, which assign specific responsibilities to departments, branches and People's Committees of wards and communes in managing, updating and cleaning house number data in the area.
Representatives of the Ho Chi Minh City Digital Transformation Center affirmed that the application of technology in house number management does not lead to having to change the current house number, so people do not need to worry.
The new point of this system is to increase people's participation. When the system comes into operation, house number data will be shared on the "Ho Chi Minh City Digital Citizen" application. People can look up their address information and report if they detect errors compared to reality.
Feedback will be received and processed online, helping functional agencies regularly update and edit data, contributing to building an accurate and synchronous address management system to serve urban management as well as digital services of the City.
