About the 858-256 exchange
858-256 is an exchange (the first six digits of a phone number) in area code 858, which covers California. NANPA, which runs the North American Numbering Plan, assigned it to Comcast (Xfinity) for the San Diego, CA rate center. Numbers from this carrier are usually landline 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 858-256 numbers is usually Pacific time. Scammers can also fake (spoof) any number, so a call that shows a 858-256 number may not come from Comcast (Xfinity) at all.
