It depends on the city. I imagine that you will have to come up with some sort of official ID to prove you are who you say you are just in case they want to tar and feather you later. A state photo ID card should suffice, or a birth cert with a Social Security card—two seminal IDs that are required to get all others. A passport. It depends on the laws are concerning what they consider proof of identification in your city, county and state.
I had a friend, back in the seventies, that ran for city council. He was a campus radical who wanted some big changes made in the city that the university was in and, although popular among the younger voters, he was an anathema to the established power. So, the city lawyer dug up some old law that said a person running for elected office in that particular county must own land.
LOL. So my buddy bought a cemetery plot which qualified him to run, but he lost the popular vote anyway. But it was great publicity and really freaked out the council. The upside was that the publicity revealed a law that could be challenge as unconstitutional, and it was, and it was removed.
