New Jersey

I had a driver's license, a passport and a gun permit. I am not sure I needed all of them.

If you are already registered you may not have to show ID at the polling station--

I have never shown ID at my polling station

If you did not provide identification to the county commissioner of registration or if the identification information could not be verified (i.e., your driver's license number or the last four digits of your social security number), YOU MUST SHOW IDENTIFICATION AT THE POLLING PLACE WHEN YOU GO TO VOTE.

Identification may include, but not limited to, Any Current and Valid Photo ID:






Driver’s license






Student or job ID






Military or other government ID






Store membership ID






United States passport




OR






Bank statement






Car registration






Government check or document






Non-photo driver’s license






Rent receipt






Sample ballot






Utility bill






or any other official document






If you show identification, you will vote in the voting machine.

If you do not show identification, you will vote by provisional ballot and have until the close of business on the second day after the election to provide identification to the applicable county election office. You will be given a hand-out at the polling place that will tell you which county election office to contact.
