About the 201-551 exchange
201-551 is an exchange (the first six digits of a phone number) in area code 201, which covers New Jersey. NANPA, which runs the North American Numbering Plan, assigned it to AT&T for the Jersey City, NJ rate center in 2017. 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 201-551 numbers is usually Eastern time. Scammers can also fake (spoof) any number, so a call that shows a 201-551 number may not come from AT&T at all.
