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 630-621 numbers is usually Central time. Scammers can also fake (spoof) any number, so a call that shows a 630-621 number may not come from Lumen (Level 3) at all.
