About the 520-770 exchange
520-770 is an exchange (the first six digits of a phone number) in area code 520, which covers Arizona. NANPA, which runs the North American Numbering Plan, assigned it to Lumen (CenturyLink) for the Tucson, AZ 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 520-770 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 520-770 number may not come from Lumen (CenturyLink) at all.
