Vietnam Address Format
Domestic Vietnamese addresses are written from the largest unit to the smallest: province/city, district (quận/huyện), ward (phường/xã), then house number + street, with the recipient last; the 6-digit postal code goes with the province line or on its own line. Since July 2025 Vietnam uses a two-tier system (province + commune/ward), so district-level units were abolished, though they still appear in legacy addresses. Outbound international mail is often reversed to the small-to-large UPU order.
