A concealed carry weapon permit (CCW) or concealed carry permit (CCP) is sometimes also referred to as a license, is an official authorization granted by a government authority that allows an individual to carry a concealed firearm in public places. The specifics of concealed carry permits can vary significantly from one jurisdiction to another, because in the U.S. regulations and requirements are typically set by state or local governments. Generally, the process involves an application, paying a fee and a review by a law enforcement agency. Many states have a training requirement.
