Mail in a registration form. You can pick one up at your local library or local Board of Elections (BOE) office.
If you are experiencing homelessness, you can register and vote. Your home address should be where you stay at night, whether it is a street corner, shelter, or any other location. This decides where you vote. Your mailing address does not have to be your home/residential address, and can be the address of a shelter, outreach center, or other place willing to receive your mail.
If you are in jail for a misdemeanor or while on probation, you can register and vote. As of May 2021, all New Yorkers after a felony conviction can, upon release from prison, immediately register to vote without special documentation. Learn more about your rights here.
