If you do not show proof of identity, you may vote only by provisional ballot. Voters who cast provisional ballots are required to fill out and sign an affidavit that explains why their provisional ballot should be counted. Provisional ballots are sealed inside special envelopes and are not put through the voting device. After Election day, County Election Board officials will investigate the information provided by the voter on the affidavit and either will approve the provisional ballot for counting or will reject it based on the outcome of that investigation. In order for a provisional ballot to be approved for counting, the information on the affidavit must match the information in the voter registration record.
