    From February 11 to June 17, 2017 Vietnam implemented an update of its geographical area code system. The change aims to unify the country's landline telephone numbering format and will result in all traditional PSTN phone numbers comprising 10 digits, area code included. Previously Vietnam used 9 and 10 digit telephone numbers.

    Hanoi and Ho Chi Minh City have gone from 1 to 2 digit area codes. The rest of Vietnam's provinces now use 3 digit area codes. The following provinces get to keep their old area codes: Vinh Phuc (211), Phu Tho (210), Hoa Binh (218) and Ha Giang (219).

    Here's a detailed article on the change published in local media and including a list of old and new area codes:
