How to Check a Contractor's License in Missouri

Missouri does not have a statewide general contractor license. If you are hiring someone to remodel your bathroom, build a deck, or finish your basement, there is no single state-issued license you can look up. Missouri leaves general contractor licensing almost entirely to cities and counties, and the rules vary dramatically depending on where you live. The state only steps in for a handful of specialty trades.

This guide covers exactly how contractor licensing works in Missouri, how to verify the licenses that do exist, what the major cities require, and what you should check when there is no state license to look up.

Does Missouri require a contractor license?

Missouri does not require a statewide general contractor license. The only contractor trade licensed statewide is electrical work, through an optional statewide electrical contractor license administered by the Office of Statewide Electrical Contractors. For plumbing, HVAC, roofing, and general contracting, licensing is handled at the local level — city by city, county by county — and requirements differ significantly across the state.

The only contractor trade that Missouri licenses statewide is electrical work. The Office of Statewide Electrical Contractors operates under the Missouri Division of Professional Registration and issues an optional statewide electrical contractor license. This license allows electrical contractors to work across the state without obtaining separate local licenses in every jurisdiction.

To qualify for a statewide electrical license, a contractor must pass a nationally accredited electrical assessment exam, carry at least $500,000 in liability insurance, and meet substantial experience requirements. These include holding a local electrical contractor or master electrician license for six of the previous eight years, or having 12,000 hours of verified practical experience, among other qualifying paths. The application fee is $200, and the license renews every three years.

For plumbing, HVAC, roofing, and general contracting, there is no state-level license in Missouri. Those trades are regulated at the local level, if they are regulated at all in a given jurisdiction.

What is Missouri's contractor license database?

Missouri's state-level license database is the MOPRO License Search, run by the Division of Professional Registration. This portal covers professions the state actually licenses — primarily electrical contractors. It is updated nightly. You can search by license number, name, or profession type. If you are looking up a general contractor, they will not appear here; that search needs to happen at the city or county level.

For the trades that Missouri does regulate at the state level, you can verify a license through the MOPRO License Search, which is the Division of Professional Registration's online verification portal. This system replaced the older licensee search tool and is updated nightly with data from the division's database.

You can search by:

• License number (fastest if the contractor provides it)
• Name (individual or business)
• Profession type (select the relevant board or trade)

A few tips for getting accurate results:

• Try the last name only first. Middle initials, suffixes, and name variations can cause the search to return no results even when the license exists.
• For business names, search with and without "LLC," "Inc.," or "Co." Contractors often register under a legal entity name that differs from the name on their truck.
• Make sure you select the correct profession type from the dropdown. Searching for an electrical contractor under the wrong category will return nothing.

The results will show the license status (active, expired, or revoked), the license type, and the expiration date. If the license shows as expired or has any disciplinary notes, ask the contractor about it directly before moving forward.

You can also reach the Division of Professional Registration by phone at 573-751-0293 or contact the Office of Statewide Electrical Contractors directly at 573-522-3280 if you need to verify an electrical license and the online system is not cooperating.

How do I check a contractor's license in Kansas City?

Kansas City contractors are licensed through the City Planning and Development Department's Permits Division. To verify a Kansas City contractor, search the city's active licensed contractor database or contact cdlicensing@kcmo.org or call 816-513-1500 (extension 1, option 2). Kansas City requires contractors to hold a city business license, a Certificate of Qualification in their trade, and at least $1,000,000 in general liability insurance. Licenses renew every four years.

Kansas City has one of the more structured contractor licensing systems in Missouri. The City Planning and Development Department administers contractor licensing through its Permits Division. Getting licensed in Kansas City involves multiple steps: obtaining a business license from the Finance Department, applying for a Certificate of Qualification in the relevant trade, and then applying for the contractor license itself through the city's CompassKC portal.

Key requirements in Kansas City include:

• Age and education - Must be at least 21 years old with a high school diploma or GED
• Qualified supervisor - Each contractor must employ a full-time supervisor who has passed an exam accredited by Prometric or ICC
• Insurance - General liability insurance of at least $1,000,000 per incident
• Fees - $55 application fee plus $167 for license issuance, with renewal every four years at $167

To verify a contractor's license in Kansas City, you can search the city's database of active licensed contractors through the Permits Division. If you cannot find someone online, contact the division at cdlicensing@kcmo.org or call 816-513-1500 (extension 1, option 2).

How do I check a contractor's license in St. Louis?

St. Louis City contractors need a Construction Industry Contractor Graduated Business License from the License Collector's Office. Search online through the city's business license search or call 314-622-4528 to verify by phone. Note that St. Louis City and St. Louis County are separate jurisdictions with different licensing requirements — a city license does not cover county work, and vice versa.

St. Louis has its own contractor licensing requirements separate from both the state and St. Louis County. Any contractor performing work within the city limits must obtain a Construction Industry Contractor Graduated Business License from the License Collector's Office.

You can search for a contractor's license online through the city's business license search tool. If you need to verify a license by phone, contact the License Collector's Office at 314-622-4528.

Additionally, contractors in St. Louis may need certification through the Building Division, which you can verify by calling 314-622-3313. For any project that requires permits, check that the contractor has pulled the appropriate building permits for your address. The city tracks permits separately from business licenses, and both matter.

St. Louis County has its own separate licensing requirements as well. The county's Department of Transportation and Public Works handles mechanical licensing for trades like plumbing, HVAC, and electrical work within unincorporated areas and participating municipalities. Do not assume that a city license covers county work or vice versa.

How do contractor licensing requirements vary across Missouri cities?

There is no uniform standard. Springfield requires a city contractor license verifiable through the Springfield contractor verification page. Independence maintains its own contractor database. Columbia, Jefferson City, and other mid-size cities each have their own rules. In rural areas and small towns, there may be no contractor licensing requirement at all. The fastest way to find out: call your local building department and ask what is required for your specific project type.

Beyond Kansas City and St. Louis, dozens of Missouri cities and counties have their own contractor licensing or registration requirements. Some are strict, and some have minimal oversight.

Independence maintains its own contractor license database and requires licensing for work within city limits.

Columbia, Jefferson City, and other mid-size cities each have their own rules. Some require contractor registration, some require specific trade licenses, and some have minimal requirements beyond building permits.

In rural areas and smaller towns, there may be no contractor licensing requirement at all. This does not mean contractors in those areas are unqualified. It means there is no government registration to verify, which puts the burden of due diligence entirely on you.

The best approach is to call your local building department or city hall and ask two questions: Does this city require contractor licensing? And if so, how can I verify that a specific contractor is licensed? This takes five minutes and tells you exactly what to check.

What should I check when there is no state contractor license in Missouri?

When no state license exists to verify, focus on insurance, bonding, references, and business registration. Request a certificate of insurance showing general liability and workers' compensation coverage, then call the insurer directly to confirm the policy is active. Check the Missouri Attorney General's office for consumer complaints. Verify the business is registered. Get a written contract with a full scope of work before signing anything. Never pay more than a third of the total cost upfront.

In a state like Missouri where general contractors do not hold a state license, what you check beyond any local registration matters even more. Here is what to verify before signing a contract:

• Insurance- Ask for a certificate of insurance showing both general liability and workers' compensation coverage. Call the insurance company directly to confirm the policy is active and that the coverage amounts are adequate for your project. Do not accept a photocopy or screenshot without verifying it. An uninsured contractor working on your property means you could be liable for injuries or property damage.
• Bonding - Some Missouri municipalities require contractors to be bonded. Kansas City, for instance, requires surety bonds. Even if your city does not require it, a bonded contractor provides financial protection if they fail to complete the work or violate the contract terms.
• References and past work - Ask for at least three recent references on projects similar to yours. Call them. Ask whether the work was completed on time, on budget, and whether they would hire the contractor again. A contractor who will not provide references is not worth the risk.
• Better Business Bureau - Check the BBB for complaints and ratings. The BBB is not a definitive signal, but a pattern of unresolved complaints is a serious warning sign.
• Missouri Attorney General - The Missouri Attorney General's office handles consumer complaints and enforces the Missouri Merchandising Practices Act, which covers deceptive practices in home improvement work. Check whether any complaints have been filed against the contractor.
• Written contract - Get everything in writing before any work begins. The contract should include the full scope of work, materials to be used, timeline, payment schedule, warranty terms, and how change orders will be handled. Never pay more than a third of the total cost upfront.
• Permits - For any work that requires a building permit, confirm that the contractor will pull the permits. If a contractor suggests skipping permits to save money, walk away. Unpermitted work can create serious problems when you try to sell your home or file an insurance claim.

What if I can't find a Missouri contractor in any database?

If the contractor is not in the MOPRO database, it is most likely because they are a general contractor and Missouri does not require a state license for that trade. That is normal. If they claim a statewide electrical license and do not appear, call the Office of Statewide Electrical Contractors at 573-522-3280 to verify. For city-level registrations, call the building department directly — online databases can be outdated. No state license, no local registration, no insurance, and no references is a clear signal to walk away.

If you search for a contractor in Missouri's state database and they do not appear, the most likely explanation is that they are a general contractor, and Missouri does not require general contractors to hold a state license. Not showing up in the MOPRO database is normal and expected for most contractors in the state.

However, if you are hiring someone specifically for electrical work and they claim to have a statewide license but do not appear in the database, that is a red flag. Ask for their license number and search again, or call the Office of Statewide Electrical Contractors directly at 573-522-3280 to confirm.

If the contractor claims to be licensed or registered with your local city, call the building department to confirm. Online databases can be outdated, and a phone call takes five minutes. Ask whether the contractor is in good standing and whether there are any complaints or disciplinary actions on file.

If a contractor has no state license, no local registration, no insurance documentation, and no references they are willing to share, walk away. The lowest bid is never a good deal if the contractor disappears mid-project or causes damage they cannot cover.

The bottom line

Verifying a contractor in Missouri takes more effort than in states with a centralized licensing system. There is no single database you can search to confirm that a general contractor is legitimate. Instead, you need to check the MOPRO database for state-licensed electrical contractors, contact your local building department for city-level licensing, and independently verify insurance, bonding, and references.

The lack of a statewide general contractor license does not mean Missouri homeowners are unprotected. Major cities like Kansas City and St. Louis have their own licensing systems, the Missouri Attorney General enforces consumer protection laws, and the state does regulate electrical contractors. But the fragmented system means you need to be more proactive about checking credentials. Do not skip the verification steps just because there is no single license number to look up. The contractors worth hiring will have no problem providing everything you need to confirm they are qualified and insured.
