How to call the United States from anywhere

December 3, 2025

Making calls to the United States from any country doesn't require relying on expensive international rates or complicated processes. Thanks to today's VoIP services, it's possible to communicate with the U.S. comfortably and, above all, affordably, whether you or your company are expanding or already operating internationally.

Making international calls to the United States is very simple with a provider that offers the right VoIP services, such as Megacall.

What is the international calling code for the United States?

To call the United States from any country, including Spain, you need to dial the U.S. international code, which is +1. This prefix identifies the United States and is always placed before the area code - which is usually made up of three digits -, since each U.S. region or city has its own local prefix. For example, an international call to New York would be +1 347 XXX XXXX

Dialing from Spain works as follows:

  • First, dial Spain's exit code, which is 00.
  • Then, dial the U.S. country code, which is 1.
  • After dialing these two prefixes (001), add the area or city code for the destination in the United States, as they vary (for example, New York: 347).
  • Finally, add the phone number you want to call.
