NANPA's central-office code records list ELECTRIC LIGHTWAVE LLC DBA ALLSTREAM (OCN 7173) as the code holder, assigned October 1, 2008. Because 206-432 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 206-432 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.
