ID is required to vote in Oklahoma. Valid forms of ID include:

– Oklahoma driver license
– Oklahoma Identification Card
– U.S. passport
– U.S. military identification
– any other document issued by the U.S. government, the State of Oklahoma, or a federally recognized tribal government if it includes your name, a photograph of you, and an expiration date that is later than the election in which you are voting (unless the identification is valid indefinitely)
– County Election Board Voter Identification Card

Furthermore, the law requires your name on any of the above documents to "substantially conform" to your name in the Precinct Registry. In other words, your name on your proof of identity must match your name in the Precinct Registry.

Student ID is not considered acceptable ID.

If you do not have any of the above forms of ID you may vote by provisional ballot and prove your identity by signing a sworn affidavit. Provisional ballots are sealed inside special envelopes and are not put through the voting device. After election day, County Election Board officials will investigate the information provided by you on the affidavit and either will approve the provisional ballot for counting or will reject it based on the outcome of that investigation.
