How to Verify a Contractor License in Missouri

TL;DR — Verifying a Contractor License in Missouri in 60 Seconds

Missouri does not require a statewide general contractor license. However, many individual trades — electricians, plumbers, and HVAC technicians — must be licensed through the Missouri Division of Professional Registration. Additionally, many cities and counties including St. Louis, Kansas City, and Springfield require local contractor licenses or permits. To verify a Missouri trade professional, search by name or license number on LicensedCheck.com or at pr.mo.gov. Confirm the license is active and matches the trade you need. Always check local municipality requirements as well since many Missouri cities have their own licensing on top of state trade licensing.

Which Missouri Trades Require State Licensing

Missouri regulates specific trades at the state level through the Division of Professional Registration. Electricians must hold a state license — classifications include journeyman electrician, residential electrician, and master electrician. Each requires passing a state exam and documenting work experience.

Plumbers are not licensed at the state level in Missouri but many municipalities require local plumbing licenses. HVAC technicians must hold EPA Section 608 certification for refrigerant handling but Missouri does not have a state HVAC license — again, local jurisdictions often fill this gap.

General contractors are not licensed at the state level. Missouri relies on local jurisdictions to regulate general contracting. This means a contractor working in multiple Missouri cities may need separate licenses for each jurisdiction. When verifying a general contractor, always ask which city or county issued their license and confirm it directly with that municipality.

Protecting Yourself When Hiring in Missouri

Because Missouri lacks statewide general contractor licensing, verifying credentials requires extra diligence. Start by searching the contractor on LicensedCheck.com for any state-level trade licenses. Then check with your local city or county building department to confirm any required local licenses or registrations.

Request proof of general liability insurance and workers compensation coverage. Get a written contract that includes the full scope of work, total price, payment schedule, start and completion dates, and any applicable license or registration numbers.

Watch for these red flags: a contractor who cannot provide any license or registration number, no proof of insurance, demands for large upfront cash payments, and pressure to skip building permits. The lack of statewide contractor licensing in Missouri means consumers must be especially proactive about verification. Search Missouri licensed professionals on LicensedCheck to confirm trade credentials, then verify local licensing with your municipality.
