Pre -numbers of countries; Comprehensive International Call Guide

The pre -numbers of the countries are part of the international numbering system that allows users to contact from one country to another. Each country has a unique preview that starts with the “+” or “1” mark, and these prefixes are used to identify the country of destination and facilitate international communication.

The pre -numbers of countries not only help make calls, but are also regional and cultural marking and can help us understand the world better. In this article, you will learn more about the pre -numbers of the world countries, their history of formation, and how to respond to anonymous foreign numbers.

Knowledge of State Number:

What is the country’s prefix?

The Country Code refers to the number used as a national ID for international phone calls. Every country in the world has a unique prefix that comes before its internal phone number. These numbers are allocated by the International Telecommunication Union – ITU and enable the contactors to correct their calls to international destinations; For example, Iran’s prefix is ​​+1 and the Netherlands is +1.

The use of pre -numbers of countries in international calls is essential for telecommunications networks to properly understand which country is directed. Failure to properly use the country’s prefix may lead to a mistake and a problem with calling. These numbers are usually one to three digits and are displayed with the “+” mark before them. This mark represents exit from the domestic network and entry into the international network.

State -numbered history

The pre -numbers of the countries for the first time in the year 5 were for Europe and expanded worldwide in year 6. At that time, the need for international calls increased rapidly. The International Telecommunications Union developed the system to provide a standard method for international dialing. In the 1980s and 1980s, the telephone systems of different countries gradually adopted countries’ prefixes to facilitate international calls. The system allowed users to easily make contact with other countries using a specific prefix.

Initially, the numbers of the countries were imported manually by telephone operators; But with the advancement of technology, this process was done automatically. This system allows users to make international calls without the need for telephone operators involved.

Since the mid -twentieth century onwards, pre -numbers of countries have become a global standard, and all countries are using the system. The International Telecommunication Union periodically reviews and updates these standards to reflect on the creation of improvement in telecommunications networks and geographical changes; For example, border changes or the creation of new countries may lead to a change in countries’ prefixes. However, the overall structure of the system remains constant and acts as an effective way to make international calls.

If an anonymous external number calls, the first step is to identify the call. You can use an online search to identify the number. If the number looks suspicious or you don’t know anymore, the best thing to do is not to answer. If the caller sends a message and you need to call, you can use the information posted on the message to identify the caller.

If you repeat anonymous or suspicious calls, you can block the number or report to your phone operator. You can also use propaganda or fraud -blocking apps. By doing so, you can prevent unnecessary disturbances and make sure your personal information is safe.
