May I work on an expired license?2022-02-09T22:46:00+00:00

NO. Working on an expired license or no license subjects you to arrest and booking. Companies or agencies that knowingly employ someone without a license subjects them to a fine and/or liability in a civil action.

How long is a license valid?2022-02-09T22:45:38+00:00

Licensed security personnel are issued a badge/identification card which must be carried/displayed while security duties are being performed. A license is good for one year and it must be renewed annually.

How many licenses may one person hold?2022-02-09T22:45:17+00:00

A person may hold a license for any number of employers as long as a letter from each employer requests it and the proper fees are paid. A separate license is issued for each company. When licensed and working for any given company, the appropriate license/ID card must be displayed on the uniform.

Do all security officers wear a uniform?2022-02-09T22:44:54+00:00

NO. As determined by the employer, some security officers are licensed in a uniform-exempt capacity and are not required to wear a uniform.

As a security officer, may I make an arrest?2022-02-09T22:44:29+00:00

Security officers have the power to arrest and detain in incidents occurring on company property. These powers are in effect only while on duty and on the premises you are paid to protect.

Must I carry a security identification card while working?2022-02-09T22:43:44+00:00

YES. The badge/identification card issued by the Private Security Section must be worn conspicuously if working in uniform or carried on the person if working in a uniform- exempt capacity. A metallic company badge may be worn but the word “police” must not be displayed anywhere on the uniform.

What type of background check is conducted when I apply for a license?2022-02-09T22:43:16+00:00

A complete background check is conducted using your name, date of birth and fingerprints. Information obtained from local police agencies, the Missouri State Highway Patrol and the FBI will be used to determine license eligibility. A felony conviction will automatically disqualify anyone from obtaining a license.

What must I bring with me when I come to the Private Security Section to apply for a license?2022-02-09T22:40:34+00:00

You must have a color photo ID (valid driver’s license or state-issued ID card), and a dated letter from your intended employer (no more than ten days old). Payment of licensing fees can be made by cash, company or personal checks, and most credit/debit cards.
