About the 650-203 exchange

650-203 is an exchange (the first six digits of a phone number) in area code 650, which covers California. NANPA, which runs the North American Numbering Plan, assigned it to Bandwidth for the Mountain View, CA 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 650-203 numbers is usually Pacific time. Scammers can also fake (spoof) any number, so a call that shows a 650-203 number may not come from Bandwidth at all.
