Eastern time
An area code can span more than one time zone. Local daylight-saving rules may differ.
What area codes overlay 220?
The NANPA source lists 740 in the same overlay complex. An overlay can serve the same broad numbering area; individual numbers still do not prove where a person is.
How do you dial a 220 number?
Use the North American country calling code +1 followed by the three-digit area code and seven-digit local number. For example, write the pattern as +1 220 XXX XXXX. Local dialing rules and charges depend on your location and provider. Check a supported dialing format or check NANPA’s 10-digit dialing list.
Do not confuse +1 220, an Ohio number, with +220, the country calling code for The Gambia. Compare country codes and area codes.
