About the 623-432 exchange
623-432 is an exchange (the first six digits of a phone number) in area code 623, which covers Arizona. NANPA, which runs the North American Numbering Plan, assigned it to T-Mobile for the Phoenix, AZ 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 623-432 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 623-432 number may not come from T-Mobile at all.
