Updated voter data for Philadelphia: Nov. 4; Montgomery County: Oct. 31.

For the first time, election officials in Philadelphia and Montgomery County are publishing updated lists of voters whose mail ballots contain deficiencies.

If you or someone you know voted by mail in Philadelphia or Montco, you can use the search tool below to learn if their ballots are among the more than 3,700 in those two counties that currently are flagged for having a problem. Common problems include missing signatures, incomplete addresses, and missing secrecy envelopes.

If you cast your mail ballot in another county, you can find out if your ballot is flagged — or simply learn if it was received and processed — by using the ballot status search tool through the Pennsylvania Department of State.

Good news: If you submitted a defective ballot, there’s still time to have your vote counted.
