Want to vote in the midterms? You'll need to pay attention to some important dates to make sure you're registered in time.

The midterm elections are coming up on Nov. 6, which means registration deadlines are coming up even faster. Here's what you'll need to know if you want a say in who's representing you in local and national offices.

When is the deadline to register to vote?

In Pennsylvania, Oct. 9 was the last day to register in person, by mail, or online.

New Jersey voters have a little more time, with Oct. 16 as the last day to register in person and by mail.

Voters in Delaware have until Oct. 13 to register in person, by mail, or online.

How do I register to vote?

Pennsylvanians can snail mail or hand deliver their voter registration to their county voter registration office or fill out the state's form online. The questionnaire asks for such information as your name, birthdate, address, and political affiliation, as well as your driver's license, ID, or Social Security number.

You can't register online in New Jersey, so voters will need to mail or hand deliver their registration to their local county commissioner of registration or superintendent of elections.

Delaware voters can register in person or by mail with their county's election office, or at other select government offices. Voters can also register via the state's online form or request by phone that an application be mailed to you.

How do I know if I need to register to vote?

Generally, you'll want to register to vote if you've never done so before in your state, have recently moved, or have changed your name.
