Minn. Stat. § 201.061
Subd. 1. Prior to election day.
At any time except during the 20 days immediately preceding any regularly scheduled election, an eligible voter or any individual who will be an eligible voter at the time of the next election may register to vote in the precinct in which the voter maintains residence by completing a voter registration application as described in section 201.071, subdivision 1, and submitting it in person or by mail to the county auditor of that county or to the Secretary of State's Office. A registration that is received no later than 5:00 p.m. on the 21st day preceding any election shall be accepted. An improperly addressed or delivered registration application shall be forwarded within two working days after receipt to the county auditor of the county where the voter maintains residence. A state or local agency or an individual that accepts completed voter registration applications from a voter must submit the completed applications to the secretary of state or the appropriate county auditor within ten calendar days after the applications are dated by the voter.
For purposes of this section, mail registration is defined as a voter registration application delivered to the secretary of state, county auditor, or municipal clerk by the United States Postal Service or a commercial carrier.
Subd. 1a. Incomplete registration by mail.
If the county auditor determines that a voter who has submitted a voter registration application by mail has not previously voted in this state for a federal office and has also not presented a document authorized for election day registration in section 201.061, subdivision 3, to the auditor, and the county auditor is unable to verify the voter's driver's license, state identification, or last four digits of the voter's Social Security number as provided by the voter on the voter registration application, then the county auditor must notify the voter that the registration is incomplete and to complete registration by using one of the following methods:

Subd. 3. Election day registration.
(a) An individual who is eligible to vote may register on election day by appearing in person at the polling place for the precinct in which the individual maintains residence, by completing a registration application, making an oath in the form prescribed by the secretary of state and providing proof of residence. An individual may prove residence for purposes of registering by:
(3) presenting one of the following:
(4) having a voter who is registered to vote in the precinct, or who is an employee employed by and working in a residential facility in the precinct and vouching for a resident in the facility, sign an oath in the presence of the election judge vouching that the voter or employee personally knows that the individual is a resident of the precinct. A voter who has been vouched for on election day may not sign a proof of residence oath vouching for any other individual on that election day. A voter who is registered to vote in the precinct may sign up to eight proof-of-residence oaths on any election day. This limitation does not apply to an employee of a residential facility described in this clause. The secretary of state shall provide a form for election judges to use in recording the number of individuals for whom a voter signs proof-of-residence oaths on election day. The form must include space for the maximum number of individuals for whom a voter may sign proof-of-residence oaths. For each proof-of-residence oath, the form must include a statement that the voter is registered to vote in the precinct, personally knows that the individual is a resident of the precinct, and is making the statement on oath. The form must include a space for the voter's printed name, signature, telephone number, and address.
The oath required by this subdivision and Minnesota Rules, part 8200.9939, must be attached to the voter registration application.
(d) For tribal band members, an individual may prove residence for purposes of registering by:
Subd. 4. Registration by election judges; procedures.
Registration at the polling place on election day shall be conducted by the election judges. Before registering an individual to vote at the polling place, the election judge must review any list of absentee election day registrants provided by the county auditor or municipal clerk to see if the person has already voted by absentee ballot. If the person's name appears on the list, the election judge must not allow the individual to register or to vote in the polling place. The election judge who registers an individual at the polling place on election day shall not handle that voter's ballots at any time prior to the opening of the ballot box after the voting ends. Registration applications and forms for oaths shall be available at each polling place. If an individual who registers on election day proves residence by oath of a registered voter, the form containing the oath shall be attached to the individual's registration application. Registration applications completed on election day shall be forwarded to the county auditor who shall add the name of each voter to the registration system unless the information forwarded is substantially deficient. A county auditor who finds an election day registration substantially deficient shall give written notice to the individual whose registration is found deficient. An election day registration shall not be found deficient solely because the individual who provided proof of residence was ineligible to do so.
Subd. 5. Unregistered voters; penalty.
No election judge in any precinct in which registration is required may receive the vote at any election of any individual whose name is not registered in a manner specified in section 201.054, subdivision 1 or not recorded under section 203B.19. A violation of this subdivision is a felony.
Subd. 6. Precinct map.
Except as otherwise provided by this subdivision, the county auditor shall provide each precinct with an accurate precinct map or precinct finder to assist the election judges in determining whether an address is located in that precinct. A county auditor may delegate this responsibility as provided in section 201.221, subdivision 4, to a municipal or school district clerk who prepares precinct maps as provided in section 204B.14, subdivision 5.
Subd. 7. Record of attempted registrations.
The election judge responsible for election day registration shall attempt to keep a record of the number of individuals who attempt to register on election day but who cannot provide proof of residence as required by this section. The record shall be forwarded to the county auditor with the election returns for that precinct.
