Notes
Arkansas licenses plumbers through the Department of Health. The Plumbing and Natural Gas section lists master, journeyman, and restricted plumber licenses along with related inspector and gas credentials, and the current Arkansas-Oklahoma reciprocity announcement says licensed Arkansas plumbers may apply for an Oklahoma unlimited journeyman license without retaking the journeyman exam if they meet the agreement conditions. Verified against Arkansas Department of Health materials and the Arkansas-Oklahoma reciprocity notice on 2026-03-09.
