Voter registration is the process by which eligible citizens sign up to participate in elections. This process typically requires individuals to provide personal information, such as their name, address, and date of birth, to ensure they meet the necessary criteria. Each state in the United States has its own rules and deadlines for registration, which can often be completed online, by mail, or in person. Once registered, voters are added to the official list of those eligible to cast their ballots in upcoming elections. Maintaining accurate voter registration lists is crucial for ensuring fair and efficient elections, as it helps prevent issues like voter fraud and ensures that each person can vote in their correct district.
