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 617-580 numbers is usually Eastern time. Scammers can also fake (spoof) any number, so a call that shows a 617-580 number may not come from Verizon Business at all.
