Part of Virginia Voter Check

This is the Fairfax County page of Virginia Voter Check, a project of True the Vote, pointing Virginia voters at the official tools that already exist — and at Scan Check Protect to verify your registration.

Where anything here differs from what Fairfax County or the Virginia Department of Elections publishes, they are right and this page is not.
