May 20, 2025 is the Pennsylvania Primary Election. Here’s what you need to know to successfully cast your ballot.

May 5, 2025 is the last day to register to vote in the Pennsylvania Primary Election on May 20, 2025. To register, visit https://bit.ly/3TfQyJn. To check your voter registration status and confirm your polling place location, visit https://bit.ly/48OzkIV. Polls are open on Tuesday, May 20, from 7 a.m. to 8 p.m. 

The deadline to request a mail-in or absentee ballot is May 13, 2025. Any registered voter may request a mail-in ballot. Absentee ballots can be requested by voters with disabilities or an illness that prevents them from going to their polling place on Election Day, or by those who will be absent from their municipality on Election Day. Request forms must be received by your county election board by 5 p.m. on May 13. Completed ballots must be received by your county election board by 8 p.m. on Primary Day, May 20. To apply for either a mail-in or absentee ballot online, visit https://bit.ly/3wYTT89.   

Pennsylvania is a closed primary state, meaning that you can only vote for candidates in the same political party you have named in your voter registration. For example, if you are registered to vote as a member of the Democratic Party, then you can vote in the Democratic primary, but not the Republican primary. All voters can vote on constitutional amendments, ballot questions, and any concurrent special election contests.
