- If you move from one election district to another in the same town or move from one town to another in Mercer County, before election day, and have not notified the Superintendent’s Office in writing of this change before the deadline date, you must go to your new polling location, in your new town or district and vote on a provisional ballot. You can call your municipal clerk or the Superintendent of Elections at 609-989-6750 to locate your new polling place.

I would prefer to register to vote using my business address. Can I do that?
No, the law requires you to register to vote using the address of your domicile. Domicile is defined as where your habitation is fixed (where you physically reside).
My child just moved onto their college campus and wants to vote there. Can they do that?
Yes. They should fill out a voter registration form for their new residence and notify this office of the change. If they wish, they may remain registered at his permanent residence, such as your home, and request a mail-in ballot be sent to them. The decision where to register and vote is up to them, nut they can only register and vote in one place.
I own two homes, where do I register from?
You must register from the place you actually reside. The words “actually resides”, mean the voter is entitled to vote only from an address where they physically live; the place you intend to return to whenever you are gone from it.
I applied for a Mail- In Ballot but never received it, what do I do?
- Prior to the elections, you can contact the Elections Division of the County Clerk at 609-989-6464 for information regarding its status.
- On the day of the election, you can go to your polling place and if your name in marked “Mail-In Ballot,” you must vote on a provisional ballot. If your name is not marked, you may vote in the machine.
What do I do if I receive a sample ballot at my home, for someone who no long lives here?
These ballots should be returned to the Superintendent of Elections Office with a brief not such as “return to sender” or “no longer lives at this address”. Such returned ballots not only include previous home owners, but family members who no longer reside at that address as well.
A returned sample ballot alerts this office that the person may no longer live at that address, prompting an investigation as to where that voter resides.
My name was tagged/missing from the poll book. What do I do?
- If your name was tagged with “Affirmation of Residence,” it means your sample ballot was returned to our office as undeliverable. If you still reside at the address we have on file, you will need to complete an Affirmation of Residence Form at your polling location. This form can be found in the binder provided at the polling location. Once completed, and if the address matches our records, you will be allowed to vote using the machine. If your current address is different from the one we have on file, you are still entitled to vote, but only by provisional ballot.
- If your name was missing, you have the right to vote on a provisional ballot only.
Where do I vote?
Voting locations are listed on your Sample Ballot or by using the Polling Place Search Tool on the New Jersey Division of Elections website at NJ DOS - Division of Elections - Election Day Polling Locations
