Vietnam country code +84 — call Vietnam & get a number.

What is the country code for Vietnam?
Vietnam answers to +84. Domestically, every number wears a trunk "0" up front — a city code for landlines, a network prefix for mobiles. The single rule for calling in from abroad: that leading 0 disappears.
So you dial your exit code, then 84, then the number with its 0 stripped off. One more thing worth flagging before you trust any Vietnamese number you find online: the 2018 reform rewrote the mobile prefixes, so older listings can be flat wrong.
Kod +84 został przydzielony Vietnam przez ITU w ramach planu E.164. The “+” oznacza „wybierz lokalny międzynarodowy kod wyjścia”; na telefonie komórkowym naciśnij i przytrzymaj 0 aby to wpisać.
Wszystkie cztery oznaczają to samo — łączą Twoje połączenie Vietnam.
How to call Vietnam from anywhere
Everything hinges on one move — peel off the domestic trunk "0" once you've added +84. Get that right and the rest falls into place.

Vietnam phone number format explained
At home, a landline is 0 + area code + subscriber number, and a mobile is a clean 10 digits: 0 followed by nine more. From abroad you drop that opening 0 in both cases. The shape you see today is recent — the 2018 reform trimmed mobiles to 10 digits and migrated the old 01xx ranges onto 03, 05, 07 and 08, which is exactly why an older 11-digit number simply won't connect now.
Telefon stacjonarny

Vietnam mobile network prefixes
The prefix after +84 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
Viettel
Vinaphone (VNPT)
Mobifone
Vietnamobile
Vietnam time zone
From Hanoi to Ho Chi Minh City, the whole country keeps one clock: Indochina Time (ICT), UTC+7, with no daylight saving to track. It shares that offset with Bangkok and Jakarta and runs an hour behind Singapore — handy anchors when you're lining up a regional call. The big gaps are with the West: a Vietnamese morning is the previous evening in the Americas.

Common mistakes when calling Vietnam
Prawie każde nieudane połączenie międzynarodowe jest problemem z formatowaniem, a nie z siecią.
Dialling an old pre-2018 mobile prefix. This is the trap that catches people most: any 11-digit 01xx mobile from before the 2018 reform is dead, having been migrated to a 10-digit 03/05/07/08 number
so a number copied from an old website, card or directory may simply not ring. Always confirm it's in the current format.
Keeping the leading 0 after +84
strip it every time you call from abroad.

Vietnam +84 — FAQ
Why won't an old Vietnamese mobile number connect?expand_more
Because of the 2018 reform. Any 11-digit 01xx mobile from before then was retired and migrated to a 10-digit 03/05/07/08 number, so older listings are often out of date — verify it's in the current format.
What exactly changed in the 2018 renumbering?expand_more
Mobiles were shortened from 11 digits to 10, and the legacy 01xx prefixes were remapped onto 03, 05, 07 and 08. Landline area codes were also standardised.
Do I drop the 0 when calling Vietnam from abroad?expand_more
Yes — strip the domestic trunk "0" after +84, every time.
What's the area code for Hanoi and Ho Chi Minh City?expand_more
Hanoi is 24 (dialled 024 at home, +84 24 from abroad); Ho Chi Minh City is 28 (028 at home, +84 28 from abroad).
How do I recognise a current Vietnamese mobile?expand_more
It's 10 digits starting 0 then 3, 5, 7, 8 or 9 — internationally written +84 followed by that prefix without the 0.
Can I tell the operator from a mobile prefix?expand_more
Roughly, but not reliably — Viettel, Vinaphone and MobiFone ranges exist, yet number portability lets numbers shift between them.
How do I call Vietnam from the US?expand_more
Dial 011, then 84, then the number with the leading 0 removed.
Does Vietnam observe daylight saving?expand_more
No. It stays on Indochina Time (UTC+7) all year, matching Bangkok and Jakarta and an hour behind Singapore.
