N.D. Cent. Code § 34-05-01.4
A person beginning work or working as an independent contractor may apply to the commissioner to receive verification of independent contractor status. The commissioner, upon receiving an application, shall review the circumstances of the applicant's job and other relevant information. When the information supports a finding under the "common law" test that the applicant will be working or is working as an independent contractor, the commissioner shall issue a determination to verify the status of the applicant as an independent contractor and shall issue the independent contractor an identification number that will be invalid if the applicant's job changes. If the applicant's job changes, the applicant may reapply for a determination to verify independent contractor status.
