In Oklahoma anyone can vote early in person at the County Election Board office - or a location designated by that office - in the county where you are registered to vote.

You may do this from 8 AM to 6 PM on Friday and Monday before all elections.

For state and federal elections only, you also can vote from 8 AM until 1 PM on Saturday before the election. 

To contact your county election board for more information, go to the local election office link on right sidebar.
