About the 307-333 exchange
307-333 is an exchange (the first six digits of a phone number) in area code 307, which covers Wyoming. NANPA, which runs the North American Numbering Plan, assigned it to Nuso for the Casper, WY 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 307-333 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 307-333 number may not come from Nuso at all.
