Licensing
Do you need a license in Missouri?
Deodorization and odor control work is generally not separately licensed in Missouri or most states. A local business license may still apply depending on your city or county, so confirm current requirements with your municipality. A NISCR certificate verifies your professional training and is not a government license.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.
