What is an International Phone Number?

International phone numbers allow businesses/individuals to field calls from other countries, which may have different dialing protocols, with the uniformity and consistency of a single number, which can be local or toll free.

For example, a converted U.S. phone number like 800 555 1234 in international format will have a '+' prefix and the country code (which is 1 in North America) in front of the number so it will look like +18005551234.
