Before you call
The international access prefix depends on the country and often the calling service. On many mobile phones, you can enter the E.164 form beginning with +1. Confirm rates and any provider-specific dialing rules with your carrier.

Is +220 the same as +1 220?
No. +1 220 uses North America’s +1 country code and Ohio’s 220 area code. +220 is The Gambia’s country calling code. This form only formats supported US and Canadian +1 destinations; it does not validate a +220 number. See more international examples.
