By understanding these regulations and syntax, you will be able to connect and communicate with your loved ones conveniently and effectively.

What is the international exit code?

The international exit code or international prefix is a code that allows you to make calls outside of the country you are in.

Each country will have its own unique international exit code. For example, Vietnam has an international exit code of 00, while Japan has 010.

When calling using a mobile phone, you can replace the international exit code with the symbol “+”.

What is the country calling code?

The country calling code is a series of numbers that represent each country in the world and that we have to enter when making international calls.

For example:

• The calling code for Vietnam is 84.
• The calling code for Japan is 81.

When calling from abroad to a mobile phone number in Japan, the phone number will be displayed with the country code [+81 Japanese phone number].

What is the area code?

For landline phones, each country will have different area codes. These codes represent specific regions, i.e., provinces/cities where the call is being received. They do not apply to mobile phones.
