Unlocking the Secrets of Telephone Country Codes: A Beginner’s Guide

Have you ever wondered how to make an international phone call? Or perhaps you’ve received a call from a foreign number and wondered which country it originated from. The answer lies in telephone country codes. These codes are essential for connecting calls between different countries and understanding where a call is coming from. In this beginner’s guide, we will unravel the secrets of telephone country codes, providing you with all the information you need to navigate the world of international calling.

What are Telephone Country Codes?

Telephone country codes, also known as international dialing codes or IDD prefixes, are numerical prefixes that allow callers to make international calls. Each country has its own unique code, which is dialed before the national telephone number when making an international call.

The International Telecommunication Union (ITU) is responsible for assigning these country codes. They consist of one to three digits and are typically assigned based on geographical regions or individual countries. For example, the United States has the country code “+1,” while Australia has “+61.”

How Do Telephone Country Codes Work?

Telephone country codes serve as a way to identify both the origin and destination of an international call. When dialing an international number, you start by entering your own country’s exit code or IDD (International Direct Dialing) prefix, followed by the destination country code and finally the local phone number.

For instance, if you’re in France (+33) and want to call someone in Italy (+39), you would dial “00” (France’s IDD prefix), followed by Italy’s country code “39,” and then the local Italian phone number.

It’s important to note that some countries have additional area or city codes that must be dialed after entering the country code but before dialing the local phone number. These additional digits help route calls within a specific region or city within a particular country.

How to Find Telephone Country Codes?

Finding the correct country code for a specific country is quite simple. There are several online resources available that provide comprehensive lists of telephone country codes. One of the most reliable sources is the ITU’s official website, where they maintain an up-to-date list of all assigned country codes.

Additionally, you can refer to various telecommunications providers’ websites or consult your local telephone directory for a list of international dialing codes. Remember to cross-reference your findings with reputable sources to ensure accuracy.


Understanding telephone country codes is essential for anyone who frequently makes or receives international calls. These codes enable seamless communication across borders and help identify the origin of incoming calls. By following the proper dialing sequence, including the exit code, destination country code, and local phone number, you can effortlessly connect with individuals around the world.

Next time you need to make an international call or receive one from a foreign number, keep this beginner’s guide in mind. With a little knowledge about telephone country codes, you’ll be able to unlock the secrets and navigate through global communication with ease.
