Notes
Mississippi does not use a statewide individual journeyman plumber license for general practice. The State Board of Contractors instead licenses plumbing classifications for commercial and residential contracting work, including a tested Plumbing classification and residential subcontractor plumbing work under the board's residential licensing framework.
