How can I tell if my plumber is licensed in Tennessee?
Ask the plumber for their Tennessee Board for Licensing Contractors license number, then verify it at the board's public lookup. The license must be Active, the class must include Limited Licensed Plumber (LLP) / CMC-A or CMC-C Plumbing, and there must be no open disciplinary actions. Groundcheck (earthmove.io/trust) does this in under 90 seconds and cross-checks court, OSHA, and BBB records simultaneously.
Confirming a plumber's license in Tennessee is a 3-step process. First, get the license number from the contractor — every legitimate plumber working in Tennessee should have one and should give it on request. If they refuse or hedge, walk away. Second, plug it into the Tennessee Board for Licensing Contractors public lookup at https://www.tn.gov/commerce/regboards/contractor.html. Third, verify three fields on the lookup result: license status (must read "Active"), expiration date (must be in the future), and disciplinary history (must be clean).
What classification matters: Limited Licensed Plumber (LLP) / CMC-A or CMC-C Plumbing. Tennessee plumbers working under any other classification are not authorized for the installs, repairs, and maintains water supply, drainage, gas, and sewer systems in residential and commercial buildings you're hiring them for. The threshold rule: Limited Licensed Plumber required for projects under $25,000; Contractor License required over $25,000. Below that threshold, the plumber may be operating legally without the state license; above it, the license is mandatory.
Red flags that the license isn't legitimate or the plumber is misrepresenting: the license number doesn't return a result, the lookup returns a different name or business than you were given, the status is "Suspended" or "Inactive," the license is in another contractor's name (the plumber is using someone else's license — illegal in every state), or the disciplinary history shows multiple open complaints.
What if the plumber won't share their license number? In Tennessee, every licensed plumber is required to display the license number on all advertising, business cards, contracts, and vehicles. If they can't or won't provide it, they're either unlicensed or hiding something.
