About the 720-204 exchange

720-204 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 Longmont, 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 720-204 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 720-204 number may not come from Lumen (Level 3) at all.
