About the 331-223 exchange
331-223 is an exchange (the first six digits of a phone number) in area code 331, which covers Illinois. NANPA, which runs the North American Numbering Plan, assigned it to AT&T Mobility for the St. Charles, IL 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 331-223 numbers is usually Central time. Scammers can also fake (spoof) any number, so a call that shows a 331-223 number may not come from AT&T Mobility at all.
