About the 303-379 exchange
303-379 is an exchange (the first six digits of a phone number) in area code 303, which covers Colorado. NANPA, which runs the North American Numbering Plan, assigned it to AT&T for the Denver, CO 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 303-379 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 303-379 number may not come from AT&T at all.
