Voting can be time-consuming. Anyone who’s had to wait in a long line or miss work to cast their ballot on Election Day (Nov. 8) or during their state’s primary can attest to that fact. If you live in a state that offers online voter registration, consider yourself lucky. Registering to vote online can save you time and an extra trip to your DMV—or, at the very least, a postage stamp.
Currently, a total of 31 states and the District of Columbia offer online voting registration. Illinois voters this year can register online to vote for the first time, beginning with the state’s primary on March 15. Legislation that would bring full online voter registration to Wisconsin was recently sent to Gov. Scott Walker’s desk.
While registering to vote on the Internet has its definite perks, voters should be mindful of deadlines and requirements that vary with each state. Beware of stricter ID protocols for online voter registration versus in-person or mail-in voter registration. Many states only accept a state-issued driver’s license or identification card online as a dual way of verifying both residency and identity. If you recently moved to a state and still have an out-of-state driver’s license, you may be out of luck in most states.
Some states require voters who register online to later verify their identity in-person. Other states that offer online voter registration don’t extend it to absentee ballots or early voting, so be sure to visit your secretary of state’s website for specific details.
