Postal code, also known as zip code or postal code, is a series of characters written in letters, numbers, or a combination of both, added to the recipient's address to identify the final destination of mail or parcels.

Per Decision No. 2334/QĐ-BKHCN issued by the Ministry of Science and Technology, effective from August 24, 2025, Vietnam's postal codes (Zip/Postal Codes) have been officially standardized to 05 (five) characters. This decision supersedes Decision No. 2475/QĐ-BTTTT dated December 29, 2017, issued by the Ministry of Information and Communications, which had been in effect since January 1, 2018.
