The 206-492 prefix belongs to area code 206 and is anchored to the Seattle rate center (WA). In NANP terms, the prefix — or NXX — determines the rate center a number is billed against.

Seattle is part of the Seattle-Tacoma-Bellevue, WA Metropolitan Statistical Area. For routing purposes it sits in LATA 674. Numbers here keep Pacific time.

NANPA's central-office code records list MCIMETRO ACCESS TRANSMISSION SERVICES LLC (OCN 7229) as the code holder, assigned September 25, 2015. Because 206-492 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 206-492 is not proof the call came from Seattle: spoofing and porting both detach numbers from their origin. To verify a caller, hang up and dial the organization's published number, and report suspicious calls to the FTC.
