650-613 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 T-Mobile for the Palo Alto, CA rate center in 2021. 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 650-613 numbers is usually Pacific time. Scammers can also fake (spoof) any number, so a call that shows a 650-613 number may not come from T-Mobile at all.
