Why is it that on some calls the phone number shown has +84 and lost the leading zero?

Tram Ho

Sometimes your phone receives calls with a very strange number, not from Vietnam but also not sure which country the number belongs to. Or sometimes you need to contact your friends, relatives, who are living abroad. Do you know that country code?

The truth is that there are 197 recognized countries in the world and several dozen unrecognized countries. Thus, the International Advisory Committee of Telegraphs and Telephones, by its Resolution No. E.164, has determined a numbering scheme for the countries. The interesting thing is that the number 8 can not only call to Vietnam, but also to Korea, Japan and China… In general, there are 9 bulk areas distributed on the planet (0) used for official purposes) like the map below:

How to call Vietnamese numbers in the country and abroad

If you are in Vietnam, you can also use the usual 0 or +84 starting format. In any case, the telecom operator will understand that you are calling within the country and will connect you to the desired subscriber without any problems. And you won’t have to pay for an international call.

If you are abroad, you need to dial from “+84”. Otherwise, the operator may think the call is internal and the person you mistakenly called will answer you.

And if you are calling from a landline and there is no “+” button, try dialing “00”. But you’d better check the international access code first with your local phone service. Currently, with 4.0 technology, as well as famous social networks, making international contacts by phone has become much easier. However, if you want to call a relative who is abroad, remember to enter the phone number in the following syntax before calling:

[00] + [ 84 ] + [Area Code] + [Phone number].

Or:

[+] + [84] + [Area Code] + [Phone number].

Example when calling out to Taiwan

Why in some calls does the phone number show +84 and lose the leading zero?

For mobile phone users, it is quite common to receive messages from the numbers +84xxxxxxxxx, which indicates that this is a strange number, the first time texting or calling you. When you receive a message with the prefix 0xxxxxxxxx. This means the number is already in your contacts.

When you first text someone, this will happen on the recipient’s phone. This is the general rule for all phone numbers under the management of the telephone network in Vietnam, is the most standard way to record phone numbers.

With mobile phones, when saving new phone numbers in contacts. You can leave +84 or change the prefix +84 to a leading zero. You don’t have to worry that you won’t be able to call that number if you don’t save it.

What if you use numbers starting 8x instead of 84 when making international calls

The number 8 in international format is assigned to China and the special zones of Hong Kong and Macau, as well as South and North Korea, Japan, Vietnam, Laos, Thailand, Bangladesh, Taiwan.

If you start the number with just 8, then most likely the call won’t go through. If you dial “+8”, then you will switch to the international level. And if such a number exists in the countries listed, there is a risk that the call will cost you dearly.

Looking up the area code with Google is the fastest method

There is also another option. Type in any search engine the query “telephone code” and the first four digits of the number: the first digit – the country code, the next three – the operator code to Google. If you call from a landline, the search engine will show the country and state/region in that country.
