1. Registration closes at 5:00 p.m. fifteen days before each election.

However, if the last day to register to vote for a regularly scheduled election falls on the day after Thanksgiving, the deadline shall be the following Monday.

3. A registration form submitted by mail shall be considered on time if it is postmarked no later than the fifteenth day before the election, even if it is received by the commissioner after the deadline, or if the registration form is received by the commissioner no later than 5:00 p.m. on the last day to register to vote for an election, even if it is postmarked after the fifteenth day before the election.

4. Registration forms submitted to voter registration agencies, to motor vehicle driver's license stations, and to county treasurer's offices participating in county issuance of driver's licenses under chapter 321M shall be considered on time if they are received no later than 11:59 p.m. on the day registration closes for that election. Offices or agencies other than the county commissioner's office are not required to be open for voter registration purposes at times other than their usual office hours.
