Country code Monaco, +377 or 00377?
There are two spellings for the Monaco area code, namely +377 and 00377. Which area code do you have to use? What is the difference between the two country codes for Monaco and what are the different versions for?
The country code of Monaco that begins with a “+” (i.e. +377) 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 Monaco using the +377 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 Monaco area code with leading zeros (00377) 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 00377
In fact, the 00377 variant applies to calls to Monaco, especially in Europe. In other countries of the world, the international code 00377 will not work. Example: In the USA, international calls to Monaco begin with 011. An international call here begins with the area code 011377.
Conclusion
For calls from UK to Monaco you can always use the country code 00377. In other countries, the two leading zeros must be replaced by a different access code. The international variant (+377) of the international country code Monaco works in all countries in the world. However, it is not supported in all networks and by all telephone devices.
