About the 720-897 exchange
720-897 is an exchange (the first six digits of a phone number) in area code 720, which covers Colorado. NANPA, which runs the North American Numbering Plan, assigned it to Lumen (Level 3) 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 720-897 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 720-897 number may not come from Lumen (Level 3) at all.
