Principles for determining administrative unit codes when there are changes
For provincial level
In case of province separation: The province with the People's Committee headquarters located at the old location will have the provincial and commune administrative unit codes unchanged. The province with the People's Committee headquarters located at the new location will be given a new province code, the commune administrative unit codes of that province will remain unchanged.
In case of province merger: The merged province with the People's Committee headquarters located in which province will have the code of that province, the code of the remaining province will be closed and will not be reissued to other administrative units. The commune code of the merged province will not change.
For commune level
- In case of commune separation: Communes with People's Committee headquarters located at the old location will have the old code. Communes with People's Committee headquarters located at the new location will be given a new code.
- In case of merging communes: The merged commune with the People's Committee headquarters located in which commune will have the code of that commune, the code of the remaining commune will be closed and will not be reissued to other administrative units.
The Decision clearly states that in case administrative units at all levels change their names or adjust from rural to urban areas or vice versa, the code will not change.
Management and use of catalogs and administrative unit codes
The Prime Minister promulgates the List and codes of administrative units in Vietnam. The Ministry of Finance (General Statistics Office) is responsible for managing the system of codes for administrative units at all levels nationwide.
Pursuant to the Resolution of the National Assembly and the Resolution of the National Assembly Standing Committee on changing administrative units, the Ministry of Finance (General Statistics Office) is responsible for arranging, closing codes, granting codes for administrative units at all levels and promptly notifying units nationwide for unified use.
The above decision takes effect from July 1, 2025.
