Missouri Engineering License

Licensing requirements for Missouri engineers and firms.

Companies that provide professional engineering services in Missouri must apply for a license with the Missouri Board For Architects, Professional Engineers, Professional Land Surveyors and Professional Landscape Architects. Before applying for a license, firms should obtain proof of their incorporation, as registration with the Missouri Secretary of State - Corporations Division is often a prerequisite to filing. Out-of-state engineering firms must qualify as foreign entities with the Missouri Secretary of State - Corporations Division prior to applying for a license.
