About the 623-755 exchange

623-755 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 AT&T Mobility for the Phoenix, AZ rate center in 2008. 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 623-755 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 623-755 number may not come from AT&T Mobility at all.
