NANPA lists Eastern for this numbering area. These are numbering-region time zones, not a caller’s current location.
An area code can span more than one time zone. Local daylight-saving rules may differ.
The NANPA source lists 878 in the same overlay complex. An overlay can serve the same broad numbering area; individual numbers still do not prove where a person is.
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 +1 724 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.
