NANPA's central-office code records list ONVOY, LLC - DC (OCN 850D) as the code holder, assigned March 18, 2019. Because 202-410 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 202-410 is not proof the call came from Washington Zone 1: 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.
