Missouri Occupational Licenses: Which State Board Licenses What

Missouri requires occupational licenses for certain professions and trades. If you're starting a business or hiring employees, you need to know which roles require state licensing, which require only local permits, and where to look them up. This guide maps Missouri's licensing landscape so you can find the right agency for your situation.

Understanding Missouri's Licensing Structure

Missouri does NOT have a unified state business license. Instead, licensing is split across multiple state agencies, local governments, and specific occupational boards. Some professions answer to the state; some answer to cities or counties; some require no license at all. This fragmented system exists by design, and understanding where your profession fits matters before you hire or before you work.

The state's regulatory framework breaks down like this: the Department of Commerce and Insurance (DCI) houses the Division of Professional Registration, which oversees most occupational licensing boards. But healthcare professions sometimes report to the Department of Health and Senior Services (DHSS). Education-related licenses go through the Department of Elementary and Secondary Education (DESE). Agricultural specialists answer to the Missouri Department of Agriculture (MDA). The Department of Revenue (DOR) handles certain regulatory roles. Other agencies, such as the Department of Commerce and Insurance (insurance producers), the Department of Public Safety (liquor and fireworks), and MoDOT (intrastate motor carriers), handle further licensing. Some professions are entirely local.

State Professional Licenses: The Division of Professional Registration

The Division of Professional Registration oversees Missouri's occupational boards. The major licensed professions under its umbrella include:

• Architects and Engineers - Must be licensed to offer services to the public.
• Accountants (CPAs) - Required if you hold yourself out as a certified public accountant.
• Appraisers - State-regulated for certain real estate valuations.
• Attorneys - Not a Division board; admitted by the Missouri Supreme Court, with discipline handled by its Office of Chief Disciplinary Counsel.
• Dentists and Dental Hygienists - Regulated by the State Board of Dentistry.
• Nurses - Licensed by the State Board of Nursing. (Nursing home administrators are licensed separately through the Board of Nursing Home Administrators under DHSS.)
• Pharmacists and Pharmacy Technicians - Licensed by the State Board of Pharmacy.
• Physicians and Surgeons - Regulated by the State Board of Registration for the Healing Arts.
• Real Estate Agents and Brokers - Licensed by the Missouri Real Estate Commission.
• Insurance Agents and Brokers - Licensed by the Missouri Department of Commerce and Insurance, not a Division board.
• Cosmetologists and Estheticians - Licensed by the State Board of Cosmetology and Barber Examiners.
• Electrical Contractors - An optional statewide electrical contractor license is issued through the Office of Statewide Electrical Contractors. Plumbers and HVAC technicians have no state board and are licensed locally.

To find the specific board for a profession, start at the Division of Professional Registration website. Each board publishes its own requirements, exam fees, application procedures, and renewal timelines. These vary widely: some professions require annual renewal, others renew every two to three years. Fees vary widely by profession. Always check the specific board for current fees and deadlines.

Healthcare and Medical Professions

Healthcare licensing in Missouri is primarily the purview of the State Board of Registration for the Healing Arts (physicians, surgeons), the State Board of Nursing (nurses and advanced practice registered nurses; nursing assistants are certified through DHSS), the State Board of Dentistry, and the State Board of Pharmacy. Some allied health professions, like respiratory therapists, require state licensure; others, like medical assistants, phlebotomists and clinical laboratory scientists, do not. Always confirm your specific role with the relevant board before claiming licensure or working without one.

Real Estate and Financial Professionals

Real estate agents, brokers, and salespersons must hold an active Missouri real estate license issued by the Missouri Real Estate Commission. Insurance agents and brokers are licensed by the Missouri Department of Commerce and Insurance. Both professions have examination requirements, background checks, and continuing education mandates. Fees and renewal cycles differ; confirm current requirements directly with each agency.

Construction, Trades, and Contractors

Missouri has NO statewide general contractor license. This means a general contractor can operate in Missouri without a state license, though they may still need workers compensation insurance, business liability insurance, and employer permits. However, specific trades often require licensure:

• Electricians: The state offers an optional statewide electrical contractor license; cities must accept it in place of an exam-based local contractor license, but many cities still license electricians locally.
• Plumbers: No state license. Chapter 341 requires master and journeyman plumbers in cities of 15,000 or more to be certified by a local board of examiners.
• HVAC Technicians: No state license; mechanical licensing is local, and refrigerant handling requires federal EPA Section 608 certification.

Local jurisdictions (Kansas City, St. Louis, and individual counties) often require additional licenses or permits for construction trades even if state licensure is not mandatory. Always check both state and local requirements before starting work.

Local-Only Licenses

Several occupations are licensed only at the local level, not by the state:

• Security Guards: Required in Kansas City and St. Louis; requirements and licensing differ by city. Contact your city's police department or licensing authority.
• Auctioneers: Licensed through the county under RSMo Chapter 343 at statutory fees; the county collector issues the license, which is valid statewide for its term.
• Pawn Brokers: Licensed by their city or county. Requirements vary by jurisdiction.
• Building and Construction Permits: Issued by cities and counties, not the state. A contractor may need a municipal license even if no state license exists.

This is why a contractor without a state license can still be required to get a city license before working in Kansas City or St. Louis. Always verify with your local city hall or county courthouse before beginning work.

How to Verify an Occupational License in Missouri

To verify that someone holds a valid Missouri occupational license, several avenues exist:

• State Professional Licensing Database: The Division of Professional Registration maintains searchable license databases for most professions. Visit the relevant board's website or the parent agency's licensing page.
• Missouri Secretary of State Business Search: If a professional operates as a registered business entity (LLC, Corporation), you can search the business name in the Missouri Secretary of State database at https://bsd.sos.mo.gov/BusinessEntity/BESearch.aspx?SearchType=0. This confirms business registration but not occupational licensure.
• Contact the Board Directly: Call or email the specific occupational board. They can confirm licensure status, current standing, and any disciplinary history.
• Check for Disciplinary Records: The Division of Professional Registration publishes disciplinary actions against licensees. Check whether a practitioner has faced suspension, revocation, or other sanctions.

License verification is particularly important when hiring contractors, medical professionals, or financial advisors. A valid license confirms current standing; the absence of a license search result does not always mean someone is unlicensed (they may work under another's license or in an unlicensed role), so ask directly.

Special Licensing Categories and Regulatory Agencies

Beyond the Division of Professional Registration, several other state agencies issue occupational licenses:

• Alcohol Beverage Control: The Missouri Department of Public Safety regulates beer, wine, and liquor licenses for bars, restaurants, and retailers. License types, fees, and local zoning requirements vary widely by municipality.
• Gaming and Wagering: Missouri's gaming commission licenses casinos and gaming employees. This is distinct from general business licensing.
• Agricultural Specialists: The Missouri Department of Agriculture licenses pesticide applicators, grain dealers, and certain agricultural professionals.
• Bail Bond Agents: SB 1421 (2026), effective August 28, 2026, moved bail bond licensing from the Department of Commerce and Insurance (Chapter 374) to the Board of Private Investigators, Private Fire Investigators, and Professional Surety Bail Bond Agents in the Division of Professional Registration (RSMo 324.2100 to 324.2187).
• Private Investigators and Security Professionals: Private investigators are licensed by the state Board of Private Investigators, Private Fire Investigators, and Professional Surety Bail Bond Agents; security guards are licensed locally. Confirm your specific jurisdiction and role.
• Notary Public: Notaries are commissioned by the Missouri Secretary of State but are not typically considered "professionally licensed." Commissioning requires an application, required training and exam, a $10,000 surety bond, and a $25 fee.

When You Do NOT Need a State License

The absence of a state license requirement does not mean no regulation exists. Many occupations are completely unregulated at the state level but may still need local permits, business insurance, or employer compliance. Examples include:

• General contractors (no state license, but may need local license and workers comp insurance)
• Bookkeepers and tax preparers (no state license, but tax preparers may need federal credentials via the IRS)
• Consultants and coaches (no occupational license)
• Marketing and sales professionals (no occupational license)
• Certain skilled trades may have local requirements but no state license

Missouri does NOT require a general state business license. Once you register your business structure (LLC, Corporation, DBA) with the Missouri Secretary of State, you can begin operations, though you may still need to register for sales tax, payroll withholding, unemployment insurance, and industry-specific licenses or permits.

Finding the Right Licensing Agency for Your Profession

If you are unsure whether your profession requires a state license in Missouri, follow these steps:

1. Determine your job title and the services you offer.
2. Check the board list on the Division of Professional Registration website (pr.mo.gov).
3. Contact the Division of Professional Registration if you suspect licensure is required.
4. Ask an industry association or mentor in your field. They often know local and state requirements.
5. Contact your city or county clerk's office for local licensing requirements.
6. If your profession involves alcohol, gaming, agriculture, or specialized fields, search for the relevant state agency (e.g., Department of Agriculture, Department of Public Safety).

For professions already regulated in other states, Missouri likely regulates them similarly, though reciprocity agreements vary. If you hold a license in another state, contact Missouri's board for your profession to ask about reciprocal or endorsement licensing.

Key Takeaway

Missouri's occupational licensing framework is profession-specific, not centralized. Some roles require state licensure; some require local permits; some require both; others require neither. The cost and complexity of licensing varies dramatically by profession. Before you hire someone or begin practicing a profession in Missouri, confirm both state and local requirements. Contact the specific occupational board or regulatory agency for your field. License verification databases are publicly available and searchable; use them to confirm that contractors, professionals, and employees hold valid credentials.
