Iowa Admin. Code r. 661-121.12
No badges, uniforms, insignia, patches, or hats will be approved for private investigative or bail enforcement agents. No holder of a license or identification card while performing the duties of a private security guard shall wear any uniform, or wear, display, or likewise use any badge, insignia, patch, shield, or the like, without prior written approval of the commissioner. Any person wearing an approved uniform shall carry a valid identification card issued by the department.
The commissioner will not approve any item subject to this rule if in the commissioner's opinion it would cause a person to confuse the operation of the licensed business with that of a law enforcement agency. The commissioner may consider the appearance of the badge, uniform, insignia, patch or hat of the requesting agency, as well as the appearance of badges, uniforms, insignias, patches or hats of law enforcement agencies in or near the area in which the requesting agency performs services. The commissioner may also consider any other information when making a decision regarding the approval of any item subject to this rule.
Badges, insignia and patches will be approved only for private security as a part of an approved uniform. No badge, insignia, patch or hat will be approved which contains the word or words "police," "officer," "policeman," or "enforcement," or the Great Seal of the State of Iowa. The words "security" and "officer" may be used when they appear as the single term "security officer."
