Telephone numbers in Vietnam

Vietnam's telephone country code is 84. The country is divided into many regions with individual area codes for landlines, as well as a separate format for mobile telephone numbers. The five emergency telephone numbers are 111 (child protection), 112 (lifesaving services), 113 (police), 114 (fire), and 115 (first aid).

Land lines

Land line telephone numbers in Vietnam follow the format area code + subscriber number. The area codes depend on the province or city.

To dial a number within the same province or city, only the subscriber number is dialed.

When dialing from a different province/city or from a mobile phone, the dialing format is 0 + area code + subscriber number.

Area codes may have from two to three digits, while subscriber numbers may have from seven to eight digits, in total, the land line telephone numbers have 10 digits.

Area codes

Area code 69

69 is the special area code dedicated for the Ministry of Defence (Vietnam) and the Ministry of Public Security (Vietnam).

Mobile telephone numbers

In Vietnam, mobile phone numbers follow the format 09x-xxxxxxx or new prefixes: 03x, 05x, 07x, 08x.

  • The first 0 is the trunk code.
  • The next two digits (3x, 5x, 7x, 8x or 9x) specify the mobile phone operator. Some mobile phone operators have been given more than one operator code.

In Circular No. 22/2014/TT-BTTTT dated 22 December 2014, all 11-digit mobile phone numbers will be changed into 10-digit numbers, the Ministry of Information and Communications announced in a recent press release. All 11-digit numbers with prefixes '012' of VinaPhone and MobiFone, '016' of Viettel, '018' of Vietnamobile and '019' of GMobile will be converted into 10-digit ones. To minimize possible loss of communications before, during and after network code change, each stage must consist of four steps as follows:

  • Make public announcement at least 60 days before the network code change starts.
  • Take technical measures to enable simultaneous dialing for 60 days since the network code change starts. Example: users may dial old or new network code 0986888888 to Viettel.
  • Maintain the notification sound (since the time of simultaneous dialing closes). During this time, any call using new network codes shall be normally processed and any call using old network codes shall be routed to the notification sound.
  • Stop maintaining the notification sound: Calls shall be successful processed only through new network codes. To ensure changing of network codes is quick and favorable for businesses and service users, steps aforementioned should be implemented for one stage.

In Communication of 31.V.2018 the Ministry of Information and Communications (MIC), Hanoi, announced a change on mobile telephony services, where all previous telephone numbers starting with 012x (mobile telephony services numbers) are moving into the other mobile number areas (e.g. to 07x or 08x etc.).
