No. Wyoming does not provide state-level plumbing licenses. All plumbing licensing is handled at the municipal level by individual cities and towns. Each municipality sets its own requirements, fees, and renewal processes. This means you must obtain a license from each jurisdiction where you plan to work.

Reciprocity agreements depend entirely on the municipality. Some Wyoming cities may honor out-of-state licenses or have reciprocity agreements, while others may not. Even with reciprocity, you may still need to undergo some training and examination. Check with the Wyoming Association of Municipalities and your specific local jurisdiction.

You can contact the International Code Council (ICC) for exam registration:
