In 32 U.S. states and in Washington DC, voter signatures on the envelopes containing mail ballots and provisional ballots are checked against signatures on file to verify the identity of each voter.

In the two-part training below, you’ll learn how to tell when two signatures have been created by the same person.

If you’re an election observer watching the signature authentication process in your local election office, watching this training will help you determine whether the process is being done without bias.

You could even apply for a temporary position with your election office and be paid to perform the signature authentication. It’s likely that this training will make you one of the most qualified candidates for such a position!

We’ve also provided for you a checklist you can download and use as a lock screen on your smart phone to remind you of the key points in the training. Choose the image size that matches your phone’s brand and model.
