Missouri Security Guard License Requirements

Missouri has no statewide license for security guards. Instead, the two big cities run their own licensing programs through their police departments. If you work security in Kansas City, you need a private officer license from the Kansas City Board of Police Commissioners. If you work in the City of St. Louis, you need a license from the St. Louis Metropolitan Police Department’s Private Security Section. Outside those cities, the rules depend on your employer and any local ordinance. This guide explains both city programs, what is required elsewhere in Missouri, armed work, and your legal authority.

Where you need a license in Missouri

Where you work	License required	Issued by	Term
Kansas City	Private officer license (Class A or B)	Kansas City Board of Police Commissioners (KCPD Private Officers Licensing)	1 year
City of St. Louis	Security license (watchman, courier, security officer)	St. Louis Metropolitan Police Department, Private Security Section	1 year
Other Missouri cities and counties	Usually none at state level; check local ordinances	Local government, if any	—

Both city programs cover off-duty police officers from other agencies working security in the city, and both require the employer to be licensed as well. If your employer sends you to posts in both cities, you need both licenses.

Kansas City private officer license

The Kansas City Board of Police Commissioners’ rules (Missouri Code of State Regulations, 17 CSR 10-2) set up two classes of licenses:

• Class A (with authority to detain or apprehend): loss prevention agents, patrol agents, certain proprietary investigators, airport police and park rangers.
• Class B (no authority to detain or apprehend): guards, armed couriers, certain proprietary investigators, and a reciprocal unarmed license for single-date events.

Requirements

• At least 18 for an unarmed license and 21 for an armed license.
• Pass a written exam. Your employer prepares you; you get up to three retakes (one per day), each with a fee.
• Annual fingerprinting and a criminal history check.
• If you served in the armed forces within the past 10 years, an honorable or general (under honorable conditions) discharge.

Criminal history in Kansas City

The Kansas City rules are strict. Disqualifiers include felony or misdemeanor convictions in state or federal court, and felony, misdemeanor or city ordinance convictions involving fraud, dishonesty, violence, bribery, illegal drugs, sexual misconduct or other moral turpitude. City DWI/DUI convictions are reviewed case by case. Armed applicants are also disqualified if they are the respondent in a current full order of protection. A previous license revocation, a current suspension, or leaving a law enforcement agency while under investigation can also disqualify you, though some of these can be appealed.

Armed officers in Kansas City

Armed licensees qualify every year at the Kansas City Police Pistol Range, completing 4 hours of handgun training and scoring at least 75 percent, the same standard used for KCPD officers. Changing weapons requires requalifying. After a failed qualification you get up to three more attempts; if all fail, you must wait a year. You can still be licensed unarmed in the meantime. Rifles require additional training and fees.

Kansas City fees

Fee	Amount
Unarmed license (Class A or B)	$110
Unarmed renewal	$85
Armed license (Class A or B)	$165
Armed renewal	$110
Annual fingerprinting	$50
Annual handgun range fee	$100
Written test failure (retake)	$85
Handgun range failure	$100
Weapon change	$100
License transfer or reinstatement	$85

Licenses expire one year after issue. A license renewed after it has expired is processed as a new application. A temporary license can be issued while your criminal history check is pending, but armed licenses are not issued until the results are back.

City of St. Louis security license

In the City of St. Louis, everyone performing a security function needs a license from the SLMPD Private Security Section, except St. Louis police officers. There are three categories:

• Watchman: observe and report only. No weapons, and no arrest, search or detention powers. Minimum age 18.
• Courier: transports property. May carry a firearm if qualified. No arrest, search or detention powers. Minimum age 21.
• Security Officer: has certain police powers only while on duty, on the premises being protected. May carry a firearm and approved protective devices if qualified. Minimum age 21.

Applicants must be a U.S. citizen or legal resident alien, have no felony convictions (an automatic disqualification) and be free of chemical dependency. Bring a color photo ID and a dated letter from your intended employer (no more than 10 days old). The background check uses your fingerprints and checks local police, the Missouri State Highway Patrol and the FBI. Licenses are good for one year. Working with an expired or missing license can get you arrested and booked.

Working security elsewhere in Missouri

Outside Kansas City and the City of St. Louis, Missouri does not license individual guards at the state level. Some cities and counties have their own ordinances, so ask your employer and check with the local police department. In practice, employers set the standards: a background check, drug screen and their own training. For armed posts, employers set firearms training and qualification rules. Missouri allows permitless carry for adults 19 and older who are not prohibited from possessing firearms, and it still issues concealed carry permits, which many employers require for armed staff.

Your authority in Missouri

Outside the St. Louis security officer category and Kansas City Class A licenses, guards have the same arrest powers as any private person. Missouri law allows a private person to make a citizen’s arrest for a felony or for certain offenses committed in their presence, but a mistake carries real liability. In retail, Missouri law (RSMo 537.125) protects a merchant or the merchant’s employee who detains a suspected shoplifter with reasonable grounds, in a reasonable manner and for a reasonable time, to investigate. Always follow your license category and post orders: a Kansas City Class B or a St. Louis watchman has no authority to detain anyone.

How to get licensed, step by step

1. Find out where your posts are. Kansas City, the City of St. Louis, or both.
2. Get a job or job offer from a licensed company; both cities require an employer.
3. Submit fingerprints and your application with the required documents and fees.
4. Pass the written exam (Kansas City) and, for armed work, the range qualification.
5. Carry your license on duty, and renew it every year before it expires.

Preparing for the Kansas City written exam

Kansas City leaves exam preparation to your employer, and each failed attempt costs $85. Prepare properly the first time:

• Ask your employer for the study material and any practice questions before you schedule the test.
• Know your license class. Class A officers may detain or apprehend; Class B officers may not. Expect questions on what each class can and cannot do.
• Learn the use-of-force basics: only reasonable force, only when allowed, and never as punishment.
• Know the paperwork: when to write a report, what goes in it, and when to call police.
• For armed applicants: review firearm safety rules and the KCPD weapons regulations form before range day.

In St. Louis, the biggest practical difference is the license category. Watchmen cannot detain anyone, so make sure your post orders match your category. If your employer expects you to detain shoplifters or trespassers, you need the Security Officer category, not Watchman.

Both cities renew every year, so set a calendar reminder at least a month before your expiration date. In Kansas City, an expired license is treated as a brand-new application, with a new exam and new fees.

Moving to Missouri from another state

Other states’ guard cards are not recognized by either city program. If you will work in Kansas City or the City of St. Louis, apply for that city’s license through your new employer. Elsewhere in Missouri, your prior license and training help you get hired, but there is no state card to apply for.

Common reasons applicants are turned down

• Any felony conviction in either city.
• A misdemeanor or city ordinance conviction involving dishonesty, violence or drugs (Kansas City).
• Failing the written exam or range qualification after the allowed attempts.
• Letting a license expire, which means starting over as a new applicant.
• No employer letter or an expired one (St. Louis).
