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 301-710 numbers is usually Eastern time. Scammers can also fake (spoof) any number, so a call that shows a 301-710 number may not come from Lumen (Level 3) at all.
