How To Call Vietnam From Singapore
Quick Reference Summary
To call Vietnam from Singapore:
001 or 008 + 84 + Area Code (without the 0) + Local Number
Examples:
- For Hanoi landline: 001 + 84 + 24 + XXX XXXX
- For Ho Chi Minh City mobile phone: 001 + 84 + 9XX + XXX XXX
When it’s 12 PM (noon) in Singapore, it’s 11 AM in Vietnam (1 hour behind).
How to Call a Landline in Vietnam
Calling a Vietnamese landline from Singapore requires following these steps:
- Dial Singapore’s international exit code: 001 or 008 (001 is generally cheaper)
- Dial Vietnam’s country code: 84
- Dial the area code (without the first 0)
- Dial the local phone number
For example, if you’re calling a Hanoi number written as (024) 3123 4567, you would dial 001 84 24 3123 4567 from Singapore.
Important: When dialing within Vietnam, landline numbers include a 0 before the area code (e.g., 024 3123 4567), but when calling from Singapore, you drop the 0 and just dial the area code after the country code.
How to Call a Mobile in Vietnam
Calling a Vietnamese mobile phone follows a similar pattern:
- Dial Singapore’s international exit code: 001 or 008
- Dial Vietnam’s country code: 84
- Dial the mobile prefix (without the first 0)
- Dial the rest of the mobile number
For example, if the Vietnamese mobile number is 090 123 4567, you would dial 001 84 90 123 4567 from Singapore.
Vietnamese mobile numbers begin with 0 when dialed within Vietnam, but from Singapore, you drop the 0 and dial the remaining digits after the country code 84.

Time Zone
Vietnam follows Indochina Time (ICT), which is UTC+7. Singapore follows Singapore Standard Time (SST), which is UTC+8.
The time difference is simple: Vietnam is 1 hour behind Singapore.
When it’s 12:00 PM (noon) in Singapore, it’s 11:00 AM in Vietnam.
Neither Vietnam nor Singapore observe daylight saving time, so this time difference remains consistent throughout the year.
Special Number Considerations
Toll-Free Numbers
If you’re trying to call a Vietnamese toll-free number (usually starting with 1800), it generally cannot be reached from outside Vietnam.
Emergency Numbers
Emergency numbers in Vietnam such as 113 (Police), 114 (Fire), and 115 (Ambulance) cannot be dialed from abroad.
Best Time to Call
Due to the minimal time difference (just 1 hour), calling Vietnam from Singapore is convenient throughout the day:
- Business hours in Vietnam: 8 AM to 5 PM (9 AM to 6 PM in Singapore)
- Evening in Vietnam: 7 PM to 10 PM (8 PM to 11 PM in Singapore)
The standard business day in Vietnam is Monday through Friday, with government offices sometimes operating half-days on Saturdays.
