About the 646-257 exchange

646-257 is an exchange (the first six digits of a phone number) in area code 646, which covers New York. NANPA, which runs the North American Numbering Plan, assigned it to Lumen (Level 3) for the New York, NY rate center. Numbers from this carrier are usually VoIP / internet 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 646-257 numbers is usually Eastern time. Scammers can also fake (spoof) any number, so a call that shows a 646-257 number may not come from Lumen (Level 3) at all.
