Voters head to the polls Tuesday for the general election. There's often confusion about what's allowed – and what's not – at the ballot box, so we've put together a guide to help you know what to expect, avoid falling for false claims and make sure you're following proper procedures.

1. You cannot vote online, by social media, by phone or by text.

2. You can check whether you're registered online, in both Pennsylvania and New Jersey.

3. You do not have to show ID to vote in most cases. The exceptions: In Pennsylvania, you must show ID if it's your first time casting a ballot at that precinct. For New Jersey voters, the only voters who need to show ID are first-time voters who registered by mail and did not provide an accurate driver's license number, non-driver ID number, last four digits of a Social Security number or other acceptable identification at that time. If you are a first-time voter and don't bring ID, you can cast a provisional paper ballot.

4. You can take a selfie in the voting booth in Pennsylvania, but you shouldn't post it until you get outside. In New Jersey, you can't post a ballot selfie.

5. You can vote after 8 p.m., as long as you get to your polling place and are in line by 7:59 p.m.

6. You cannot register to vote on Election Day.

7. You can wear clothes, buttons or hats to show support for your favored candidates but you cannot otherwise campaign for those candidates at the polling location. You can bring campaign literature with you into the voting booth, but you should take it with you when you leave.

8. You should use your state Department of State's official website to check your polling place; don't follow the directions from a robocall or mailing.

9. You can get help if you think your voting rights are being violated. Resources include the Committee of Seventy, the Justice Department's district election officer for eastern Pennsylvania (215-861-8200), the local FBI field office (215-418-4000), the DOJ Civil Rights Division's Voting Section (1-800-253-3931 or 202-307-2767;, the Philadelphia District Attorney's Office Election Fraud Task Force (215-686-9641, 9643 or 9644) and the New Jersey U.S. Attorney's Office Election Day hotline (888-636-6596).
