About the 720-340 exchange

720-340 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 Verizon Wireless for the Longmont, CO rate center in 2009. 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 720-340 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 720-340 number may not come from Verizon Wireless at all.
