About the 770-220 exchange
770-220 is an exchange (the first six digits of a phone number) in area code 770, which covers Georgia. NANPA, which runs the North American Numbering Plan, assigned it to AT&T for the Atlanta, GA rate center. Numbers from this carrier are usually landline lines.
People keep their number when they move or switch carrier, so this is where the number was first assigned, not where the caller is today. Local time for 770-220 numbers is usually Eastern time. Scammers can also fake (spoof) any number, so a call that shows a 770-220 number may not come from AT&T at all.
