Minnesota DLI credentials

Minnesota Contractor License and Registration Lookup

Search DLI residential contractor business licenses and construction contractor registrations. A registration is distinct from a license and does not replace one when licensing is required.

Verify a contractor license

Free public lookup: up to 10 search or verification requests per IP each UTC day.

Results are informational and should be confirmed against the official Minnesota Department of Labor and Industry (DLI) record before making a hiring or compliance decision.
