Election Information
Voter Registration
To qualify as a voter, a resident must register after meeting four requirements: (1) eighteen years of age, (2) a U.S. citizen for at least one month, (3) a resident of the precinct at least 30 days, (4) a resident of Pennsylvania for at least 30 days. Voters who move within the state within 30 days prior to an election may vote in that election at their previous precinct. Registration is permanent unless an elector moves to another precinct or fails to vote for two consecutive years.
Electors may register at the Chester County Government Services Building, 601 Westtown Road, West Chester. Those who prefer mail-in registration may obtain forms at state liquor stores, county libraries, township or municipal buildings or some post offices on announced dates. Registration books close 30 days before any election and are reopened five days after a Primary Election and 30 days after General or Municipal Election.
