About the 773-306 exchange

773-306 is an exchange (the first six digits of a phone number) in area code 773, which covers Illinois. NANPA, which runs the North American Numbering Plan, assigned it to AT&T for the Chicago, IL rate center. Numbers from this carrier are usually VoIP / internet phone 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 773-306 numbers is usually Central time. Scammers can also fake (spoof) any number, so a call that shows a 773-306 number may not come from AT&T at all.
