Drop the 0. If it starts 01, it needs a new start.
Vietnamese numbers begin with a 0 at home, and that 0 disappears after +84. Mobiles saved before September 2018 have 11 digits and a start that no longer exists. Swap the first digits and the call goes through.

Vietnam has 34 provinces now. The old codes still ring.
On 1 July 2025, 63 provinces became 34. Each merged province is due to get one area code, but until that happens every old code keeps working, so the landline you have saved still connects.

Your evening is their afternoon. Call a little later.
Vietnam keeps UTC+7 all year. Australia's east coast moves its clocks, so the gap is 4 hours in summer and 3 in winter, while Perth stays 1 hour ahead. Pick your city to see when they are home.

Calling Vietnam: your questions
Reviewed 29 October 2026.
What is the country code for Vietnam?
Vietnam's country code is +84, and the 0 that starts every Vietnamese number is dropped behind it: 0912 345 678 becomes +84 912 345 678, and the Hanoi number 024 3812 3456 becomes +84 24 3812 3456.
How do I call Vietnam from Australia?
Australians press 0011 84 and the number less its 0: 0011 84 912 345 678 for a mobile, 0011 84 28 plus eight digits for Ho Chi Minh City. A smartphone or SIP app takes +84 in place of 0011 84. Sydney is 3 or 4 hours ahead of Vietnam, Perth 1 hour.
How do I call Vietnam from the USA, UK or Canada?
North America uses 011 84 and the UK 00 84. Leave off the Vietnamese 0 afterwards, so 0912 345 678 is called as 011 84 912 345 678. Starting with +84 on a cell phone works from any of the three.
How do I call a Vietnamese mobile?
Vietnamese mobiles are written with 10 digits starting 03, 05, 07, 08 or 09. Behind +84 the 0 goes and nine digits are left: +84 912 345 678. Vietnamese numbers can switch networks, so 09 or 03 does not prove which carrier it is.
My family's number has 11 digits and starts 01. Does it still work?
Not as written. In September 2018 every 11-digit mobile moved to 10 digits: 0168 123 4567 is now 038 123 4567, and 0123 became 083. The last seven digits stayed the same. The reader at the top turns a saved 01 number into its 10-digit form.
What are the area codes for Hanoi and Ho Chi Minh City?
Hanoi is 024 and Ho Chi Minh City is 028, dialled as 24 and 28 after +84, followed by eight digits. Before 2017 they were 04 and 08; those old codes no longer connect.
Did area codes change when Vietnam merged its provinces in 2025?
Not yet. Vietnam went from 63 provinces to 34 on 1 July 2025. Merged provinces have a planned single code, but the old codes of every area keep working side by side for now, so a number you already have still connects.
What is the time difference between Australia and Vietnam?
Vietnam is on UTC+7 all year, with no daylight saving. Sydney, Melbourne and Canberra are 4 hours ahead from October to April and 3 hours ahead the rest of the year. Brisbane is 3 hours ahead, Adelaide 3 hours 30 or 2 hours 30, Darwin 2 hours 30 and Perth 1 hour.
How much does it cost to call Vietnam?
$0.0250 a minute to a 09 mobile in Hanoi or a 028 line in Saigon, with nothing charged to connect. Half an hour with Mẹ comes to $0.75, and a $20 top-up holds 800 minutes. Each call is charged in whole minutes, rounded up.
Can I call a 1800 or 1900 number in Vietnam from abroad?
Usually not. 1800 numbers are free for callers inside Vietnam and 1900 numbers are premium rate; neither is meant for international calls, and we block premium-rate lines. Ask for a mobile or landline instead.
Do I need a Vietnam calling card?
No. Save the number as +84 912 345 678, with the 0 gone, and call it from your contacts. From Hải Phòng to Cần Thơ, the price is $0.0250 a minute.
Hanoi, Saigon or the Mekong, one rate. 800 minutes for $20.
Bring an email address and $20 of crypto, and you are set up. From Australia that means 0011 84, in the app +84, then the number with its 0 gone. How sign-up and top-ups work.
