A "certified contractor" is a statewide contractor licensed at the state level. Certified license numbers begin with the letter "C".
A "registered contractor" is a contractor who has a county license (or multiple) who then had to register that license with the state because it was a major trade. Registered contractors can only work in the county in which they have a competency card. Registered contractors are designated by an occupation code which begins with the letter "R".
The Construction Industry Licensing Board does not have a reciprocal agreement with any other state, but applicable out-of-state work history will work toward your experience requirements.
The Electrical Contractors’ Licensing Board will allow reciprocation for the Unlimited License with North Carolina, California, and Georgia. *restrictions apply
