Which of the following is NOT required as part of an application for a Minnesota contractor license?

The choice regarding the unemployment insurance account number is correct because it is not a requirement for obtaining a contractor license in Minnesota. When applying for a contractor license, applicants typically must provide proof of liability insurance, workers' compensation insurance, and sometimes evidence of group health insurance, depending on the requirements for their specific contracting activities.

Liability insurance protects against claims for injuries or damages that may occur as a result of the contractor’s work, while workers' compensation insurance is mandated to provide benefits to employees who may be injured on the job. However, the regulations do not generally include a requirement for proof of an unemployment insurance account number in the licensing process. Therefore, this option stands out as the element that is not typically necessary when applying for licensing as a contractor in Minnesota.
