About the 405-400 exchange
405-400 is an exchange (the first six digits of a phone number) in area code 405, which covers Oklahoma. NANPA, which runs the North American Numbering Plan, assigned it to Onvoy (Sinch) for the Oklahoma City, OK rate center in 2015. 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 405-400 numbers is usually Central time. Scammers can also fake (spoof) any number, so a call that shows a 405-400 number may not come from Onvoy (Sinch) at all.
