What Happened to Vietnam's Old Provinces?
A detailed look at Vietnam's province consolidation and the fate of 29 former provinces.
The Province Consolidation of 2025
Vietnam's 2025 administrative reform resulted in the dissolution of 29 former provinces and municipalities, merged into the 34 new provinces and centrally-run cities that form today's first-level administrative divisions. Understanding what happened to these old provinces is essential for anyone researching Vietnam's administrative history, tracing family histories, or needing to locate records from pre-reform addresses.
The consolidation was part of a broader government efficiency initiative aimed at reducing administrative overlap, cutting costs, and streamlining the chain of command from central to local government. Each old province was dissolved and its territories redistributed to one or more successor provinces.
Merged Provinces and Their Successors
The following provinces were merged into existing provinces:
Northern Region: Several northern provinces were consolidated. For example, some mountain provinces were merged with their lowland neighbors to create larger administrative units with better economic development potential.
Central Highlands: Provinces like Đắk Nông was merged into Đắk Lắk, combining agricultural regions for better resource management and economic development planning.
Mekong Delta: Multiple small provinces were merged to reduce administrative costs and improve service delivery. Provinces like Hậu Giang were created from parts of former provinces.
Southern Region: Bình Dương and Bình Phước were reorganized, along with Bà Rịa–Vũng Tàu maintaining its status while other areas were consolidated.
What Happens to Old Province Records?
Administrative records from dissolved provinces are not destroyed. They are typically transferred to the successor province's People's Committee archives. However, the transfer process can take time, and some records may temporarily be harder to locate.
For legal documents (land titles, birth certificates, marriage certificates): These remain legally valid regardless of administrative changes. Contact the successor province's Department of Justice or the local People's Committee where the property or event is now located.
For historical or genealogical research: Records are generally transferred to provincial archives in the successor province. Some records may be digitized and available through government portals.
Address Changes After the Merge
When provinces are merged, street addresses and administrative boundaries change. However, Vietnam's addressing system is primarily commune/ward-based rather than province-based for most practical purposes.
If you need to update addresses on documents: The change from an old province name to a new province name may require updating identification documents, business licenses, and land use rights certificates. This is typically done through the local People's Committee.
Postal services: Vietnam Post has adapted to the new administrative boundaries. When sending mail, use the new province name along with the district and commune/ward names.
Understanding Pre-Reform Addresses
Many historical documents, maps, and databases still reference the old 63-province system. Here's how to interpret old addresses:
Old Format: Province → District → Commune → Village/Hamlet New Format: New Province → District → Commune/Ward → Village/Hamlet
The district and commune/ward levels generally remain unchanged, so most local addresses remain valid. Only the province name has changed. For example, if your old address listed "Tỉnh X" and X was merged into Y, your new address would list "Tỉnh Y" (or "Thành phố Y" if Y is a centrally-run city).
Finding Your Successor Province
To determine which new province your old province became part of:
1. Identify the old province name from documents, records, or historical sources 2. Cross-reference with the 2025 merger map showing which provinces were combined 3. Contact the local People's Committee in the area for official confirmation 4. Check the successor province's government website for archived information about the merger
