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).

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.

3x	5x	6x	7x	8x	9y
			70 - MobiFone		90 - MobiFone
				81 - Vinaphone	91 - Vinaphone
32 - Viettel	52 - Vietnamobile			82 - Vinaphone	92 - Vietnamobile (previously HT Mobile)
33 - Viettel				83 - Vinaphone	93 - MobiFone
34 - Viettel				84 - Vinaphone	94 - Vinaphone
35 - Viettel	55 - Reddi			85 - Vinaphone	95 - obsolete (previously S-Fone)
36 - Viettel	56 - Vietnamobile		76 - MobiFone	86 - Viettel	96 - Viettel (previously EVN Telecom)
37 - Viettel		672xxxxxx(New VSAT prefix)	77 - MobiFone	87 - Indochina Telecom	97 - Viettel

39 - Viettel	59 - Gmobile		79 - MobiFone	89 - MobiFone	99 - Gmobile (previously Beeline)

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.

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.).^[3]
