N.D. Cent. Code § 16.1-11.1-06
The county auditor shall appoint a mail ballot precinct election board for the purpose of counting mail ballots in the same manner as prescribed in section 16.1-07-12.1. The board may begin scanning the ballots at any time beginning three business days before election day and the closing of the polls on election day. Results from the mail ballot precinct may be counted, canvassed, or released under chapter 16.1-15 as soon as any precinct within the county, city, or legislative district closes its polls on the day of the election. The county auditor shall designate a location for the closing, counting, and canvassing process under chapter 16.1-15, which location must be open to any person for the purpose of observing. The board shall comply with the requirements of sections 16.1-15-04 through 16.1-15-12 as applicable. A county conducting a mail ballot election constitutes one voting area, and ballots need not be sorted according to precinct or ward unless necessary for the administration of the election.
