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

Land lines

Land line phone numbers in Vietnam follow the format Area Code + Phone Number. The area codes depend on the province and/or city. To dial a number within the same province or city, only the phone number needs to be dialed. When dialing from a different province/city or from a mobile phone, follow the format 0 + Area Code + Phone Number. At the moment, area codes may have from 2 to 3 digits, while phone numbers may have from 7 to 8 digits, in total, the land line phone numbers in Vietnam have 11 numbers included trunk code (0). The different area codes are described below.

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: 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.).
