Code-holder of record: ONVOY, LLC - WA (OCN 483E), assigned March 12, 2012. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 206-209 numbers may be served by different companies.

Caller ID showing 206-209 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.
