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 267-423 numbers is usually Eastern time. Scammers can also fake (spoof) any number, so a call that shows a 267-423 number may not come from T-Mobile at all.
