Vietnam Postal Code: Postcodes for Ho Chi Minh City, Ha Noi and All 34 Provinces

Vietnam's postal codes have changed more than once. They have been 5 digits since 1 January 2018, replacing the 6-digit codes used before⁽¹⁾. On 1 July 2025 Vietnam reorganized its provinces from 63 down to 34⁽²⁾, and Decision No. 2334/QD-BKHCN of 24 August 2025 assigned new codes to each ward and commune⁽³⁾.

Which Vietnam ZIP Code Should You Use?

Purpose	Use	Example
Registering an account, shopping online, or filling in a website form	Province-level code Most forms only check the format, not the real location.	Ho Chi Minh City -> 70000 Hanoi -> 10000
Filling in a form that will not accept fewer than 6 digits	The 5-digit code with a zero on the end Some older forms still expect the longer format.	70000 -> 700000
Sending mail, a postcard, or a parcel to Vietnam	The exact ward code Anything physical needs the real code for that ward.	Sai Gon Ward -> 71016

Some older websites still ask for 6 digits. If a form rejects the current 5-digit code, adding a trailing zero may get it through, but that longer number is not an official postal code.
