Okla. Admin. Code § 230:35-5-52.1
Two or more entities may hold elections on the same date. School districts, municipalities, and some other entities have boundaries that do not follow precinct lines, with the result that a precinct may contain more than one school district or municipality. Any combination of these entities may hold elections on the same day. A voter must be registered to vote at an address within the boundaries of a school district or a municipality to vote in a school district or municipal election. The Precinct Registry lists a code for the school district or municipality in which a voter is eligible to vote. (If no school district or muncipal code is listed for a voter or if the voter says the school district or municipal code listed is incorrect, see 230:35-5-113.2.) It is, however, the voter's responsibility to determine his or her own eligibility to vote in elections held by certain other entities. If a voter is uncertain of his or her eligibility to vote in an election, the Judge shall show the voter a map of the precinct that shows the entity's boundary line.
