Okla. Admin. Code § 230:30-9-4
Yellow, pink or green Applications for Absentee Ballots received from persons who are not registered to vote in the county must be forwarded immediately to the appropriate County Election Board. If the appropriate County Election Board cannot be determined, or if there is no evidence that the voter is registered to vote in any county, the application shall be rejected. If such an application is received, some information must be entered into MESA to create a letter to the voter rejecting the application. [26:14-133] The information which must be entered includes the person's name, address and the election or elections for which ballots were requested. If the rejected application is from an in-person absentee voter, MESA will not create a letter.
