Election Day is here on Tuesday, and even if you’re not certain about your voter registration status, numerous states permit registration right up until the polls close.

Over 20 states, along with Washington, D.C., allow voters to register and vote on the same day. However, in some states, this option is limited to voting for president and vice president.

North Dakota stands out as the only state that doesn’t mandate voter registration, so eligible residents can simply go vote without having to register beforehand.

Usually, you will need to provide proof of residency and identification to register. It’s advisable to consult your local election administrators for specific details at Vote.gov.
