Country code USA, +1 or 001?

There are two spellings for the USA area code, namely +1 and 001. Which area code do you have to use? What is the difference between the two country codes for USA and what are the different versions for?

The country code of USA that starts with a “+” (i.e. +1) is the so-called international code (international spelling). It is primarily used in the mobile communications sector. Most cell phones can make an international call to the United States using the +1 area code. This applies to almost every country in the world.

Unfortunately, there are phones (especially older models) that do not support the international spelling. The USA area code with leading zeros (001) is then used on these phones. The leading zeros are also referred to as the so-called traffic elimination number. When you call, they indicate that it is an international call.

Problem: Access code and area code 001

In fact, the 001 variant is used for calls to the USA, especially in Europe. In other countries of the world, the international code 001 will not work. Example: In the USA, international calls to the USA begin with 011. An international call here begins with the area code 0111.

Conclusion

For calls from UK to the USA you can always use the country code 001. In other countries, the two leading zeros must be replaced by a different access code. The international variant (+1) of the international country code USA works in all countries in the world. However, it is not supported in all networks and by all telephone devices.

Example of calls to the USA

001 123 456789

If you use a mobile phone, the following notation also applies worldwide:

+1 123 456789
