Calling in & to Vietnam: Best Calling Apps & Country Codes

Staying connected in Vietnam is easy, whether you’re calling locally or internationally. With affordable SIM cards, internet calling apps, and a straightforward country code system, you have plenty of options. This guide covers the best ways to make calls to and within Vietnam, ensuring you’re always reachable.

Subjects

Vietnam country code

Vietnam’s country code is +84. This is required for international calls to Vietnam, ensuring that the call is routed to the correct country.

Calling to Vietnam from abroad

  • To call a number in Vietnam, dial +84, followed by the area code (if applicable) and the local number.
  • Example: To call a number in Hanoi, you would dial +84 24 [local number] (where 24 is Hanoi’s area code).
  • For mobile numbers, skip the area code and dial directly after +84.

Calling locally in Vietnam

1. Calling mobile numbers in Vietnam

  • When calling mobile numbers, area codes are not needed, regardless of where you are in the country. Mobile numbers in Vietnam are typically 10 digits long and start with prefixes such as 09, 08, or 03. Simply dial the entire mobile number directly.

2. Calling landline numbers

  • If you’re in Vietnam, you only need to dial the local number. However, if you’re calling a different region, you’ll need to include the area code.
  • Example: If you’re in Ho Chi Minh City (area code 28) and want to call Hanoi (area code 24), dial 024 [local number].

International calls from Vietnam

To call a number outside Vietnam, you’ll need to use the international dialing prefix 00, followed by the country code, area code, and local number.

  • Example: To call a number in the United States, dial 00 1 [area code] [local number].

Common country codes:

  • United States: +1
  • United Kingdom: +44
  • Australia: +61
  • Netherlands: +31

Internet calling in Vietnam

Why choose internet calling?

Internet calling is an affordable or even free option for staying connected in Vietnam. All you need is an internet connection—no phone credit required—which makes it especially convenient for travelers relying on Wi-Fi or mobile data. It’s perfect for both local and international calls, as well as quick messaging.

Popular apps for internet calling

1. WhatsApp

Widely used internationally and increasingly popular among those in Vietnam’s tourism sector. It’s an excellent choice for communicating with local guides, hotels, and tour operators.

2. Messenger

Integrated with Facebook, Messenger is great for staying in touch with friends and family already connected to your account.

3. Skype

A reliable option for international calls, especially to landlines, making it ideal for business or more formal communication.

Vietnam’s most popular messaging app among locals. While tourists may not use it as often, many Vietnamese use Zalo for daily communication. It’s worth considering if you plan to interact frequently with locals.
