Dear Gail, on BuildZoom, contractors may update their license information. These updates go into a queue that our research team goes through, verifying updated license info with the proper board before accepting the update. Once the change has been accepted, you’ll see an indicator on the profile stating, “Info verified.”

In this case, the license updates had not yet been reviewed by our research team but we investigated your question and weren’t able to reconcile the information with the Florida licensing board and have made the appropriate changes to the profile.
