  • Be at least 16 years old to preregister (must be 18 by Election Day to vote)

What ID to bring

If your situation is unusual

Homeless voters

Use any physical location as your “home base” where you regularly return and intend to remain (park, vacant lot, shelter, campground, bus station, or other location). You must provide a mailing address for ballot delivery — a PO box works for that. PO boxes cannot be used as residence addresses.

Foreclosure or eviction

A foreclosure or eviction notice does NOT affect your voting rights. Still living there: no registration change needed. Moved: update your registration with your new “home base.” Moved out of state: register in your new state.

Displaced by natural disaster

If displaced by fire, flood, tornado, or other natural disaster, you may keep your previous address while temporarily displaced. If you have a new permanent residence, update your registration. If you plan to return, stay registered at the previous address. You may need to update your mailing address for ballot delivery.
