About the 909-377 exchange
909-377 is an exchange (the first six digits of a phone number) in area code 909, which covers California. NANPA, which runs the North American Numbering Plan, assigned it to AT&T Mobility for the Upland, CA rate center in 2015. Numbers from this carrier are usually wireless (cell 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 909-377 numbers is usually Pacific time. Scammers can also fake (spoof) any number, so a call that shows a 909-377 number may not come from AT&T Mobility at all.
