A quick read on how it works.
A Vietnamese phone number in international format is written as +84 [area code without leading 0] [subscriber]. Drop the leading 0 internationally. Example: +84 24 1234 5678 for Hanoi (domestic 024), +84 912 345 678 for a Viettel mobile (domestic 0912).
Vietnamese mobile numbers all start with 3, 5, 7, 8 or 9: Viettel uses 086/096/097/098 + 032-039; Vinaphone uses 088/091/094 + 081-085; MobiFone uses 089/090/093 + 070-079; Vietnamobile uses 092 + 056/058. All Vietnamese mobiles are 10 digits domestic.
Where a +84 number reaches.
From Hanoi's Old Quarter to HCMC's District 1 to Ha Long Bay, every Vietnamese number lives behind a +84.
How to call Vietnam from any country.
