+84: What is it? How to use a phone number with the country code +84

When receiving messages from an unsaved number on your phone, it often starts with +84. Sometimes, incoming calls may also start with +84 or 0084 instead of the usual starting digit 0. Are you wondering why it starts with +84 and what +84 means? If you're seeking answers about the +84 prefix, join Mytour to explore What is +84? How to use a phone number with the country code +84 in the following article.

I. Understanding +84

+84 or 0084 both represent the international dialing code for Vietnam. This code is used when making calls from abroad to Vietnam. Inputting a phone number with the usual starting digit 0 wouldn't enable international calls to Vietnam.

International phone numbers are typically written with a plus sign (+) followed by the country code. Thus, a Vietnamese phone number would be written as +84 followed by the number. However, when dialing, you only need to press 84 or 0084 to connect internationally to the Vietnamese number you desire. Not only in international calls but even within Vietnam, you can still make calls with the usual 0 prefix or +84.

II. How to Use Phone Numbers with Country Codes

International dialing codes or country codes are the initial digits required when making international calls. The international standard for making calls outside each country is the code 00, accepted by nearly all countries worldwide. Usually, country codes are used when contacting phone numbers in other countries, but sometimes domestic calls or when receiving messages from unknown numbers may display +84 instead of 0.

If you're within Vietnam, you can still use the format starting with either 0 or +84. Telecom providers will still understand that you're trying to connect to a domestic subscriber and charge you according to regular call rates rather than international call charges. However, when calling from abroad to Vietnam, you must dial +84 or 0084 to initiate the call. When receiving calls or messages, you'll see the +84 prefix as it's the convention for international phone numbers, but when dialing, you only need to input 84 or 0084 to connect.

The convention for using phone numbers with country codes is as follows:

[+] + [Country Code] + [Area Code] + [Phone Number]

International phone numbers are usually written with a plus sign (+) followed by the country code, area code (if it's a landline), and then the phone number to contact. However, when inputting an international phone number to make a call, you enter it as follows:

[00] + [Country Code] + [Area Code] + [Phone Number].

Example: A phone number in Vietnam is 0123 456 789

- The phone number with the country code will be written as follows: +84 123 456 789

- When making a domestic call, dial the number 0123 456 789

- When making an international call to Vietnam, dial the number 00 84 123 456 789

III. International Telephone Area Codes

International phone numbers follow the international standard set by the International Telecommunication Union (ITU-T) through Resolution E.164. According to this standard, each country is assigned a code, and Vietnam's country code is +84. Additionally, 0084 is also the telephone area code for Vietnam. In reality, there are 197 recognized countries worldwide, and Resolution E.164 assigns numbers to ensure uniqueness for each country's telephone area code.
