Land lines

Mobile telephone numbers [1][2]

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 2 digits (3x, 5x, 7x, 8x or 9y) specify the mobile phone operator. Some mobile phone operators have been given more than one operator code.
3x5x 6x 7x 8x9y
70 - MobiFone 90 - MobiFone
81 - Vinaphone91 - Vinaphone

In Circular No. 22/2014/TT-BTTTT dated December 22, 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, step a aforementioned should be implemented for one stage.
