A voter ID law in the United States mandates or requests voters to present proof of identity before casting their ballot. The accepted types of proof vary by state, with some accepting only photographic identification, such as a driver’s license or passport, while others also accept nonphotographic documents, like a utility bill or a rent receipt.
By the second decade of the 21st century, more than two thirds of U.S. states had laws requiring or requesting voters to provide identification at the polling place.
