How do I check a plumber's license in Mississippi?
Search the plumber's license number, business name, or personal name at Mississippi State Board of Contractors (www.msboc.us). Status must be Active. Look for the Plumbing (Commercial / Residential) class. A free public-records check on Groundcheck (earthmove.io/trust) cross-references this with court records, OSHA, and BBB.
To verify a plumber in Mississippi, search the Mississippi State Board of Contractors database. The lookup tool is at https://www.msboc.us/. Mississippi requires this license required for commercial work over $50,000 or residential work over $50,000.
What to enter: the contractor's license number is the fastest path. Most state boards also let you search by business name or personal name. Confirm the license shows the Plumbing (Commercial / Residential) class — that's the specific classification authorizing installs, repairs, and maintains water supply, drainage, gas, and sewer systems in residential and commercial buildings.
What to look for: status must be "Active." Status of "Inactive," "Suspended," "Expired," or "Revoked" is a hard stop. Check the bond amount (most boards require contractor bonds), expiration date (renewals lapse if a contractor falls behind on continuing education), and any open complaints or disciplinary actions in the public record.
What the lookup does NOT show: liability insurance and workers' compensation coverage are typically separate from the state license database. Ask the plumber for current Certificates of Insurance and verify directly with the insurer.
What Groundcheck adds: a plumber can be currently licensed and still have unresolved court judgments, OSHA citations, or BBB complaints. Groundcheck (earthmove.io/trust) cross-references the Mississippi State Board of Contractors record with Secretary of State filings, public court records, federal OSHA inspection history, and BBB complaint history into one sourced report. The contractor is never notified.
