Notes
Missouri's official Division of Professional Registration board listings reviewed on 2026-03-09 include Electrical Contractors and Cosmetology and Barber but do not identify a statewide plumbing licensing board. This record reflects an inference from those official Missouri licensing materials that plumbing licensing is generally handled outside a single statewide professional board, often through local jurisdictions.
