Mobile telephone numbers

In Vietnam, mobile phone numbers follow the format 01yy xxx-xxxx or 08y xxx-xxxx or 09y xxx-xxxx (where y is 0-8) or 099y xxx-xxx.

• The first 0 is the trunk code.
• The next 2 or 3 digits (1yy or 8y or 9y or 99y) 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 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 network code 016xxxxxxxx or new network code 044xxxxxxx 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.

The mobile phone operator codes are distributed as followed:
