Issuing authorities from all 9 states included in GAO's case study stated that they take action to confirm an individual's continued eligibility to hold a permit as part of the permit renewal process; and issuing authorities from 8 of these 9 states reported using mechanisms to monitor resident permit holders' continued eligibility between issuance and renewal. In these 8 states, issuing authorities told GAO that they are notified if a permit holder commits a disqualifying act within their state through law enforcement or state databases. After detecting a disqualifying criminal offense or other disqualifying factors, each of the 9 states begins the revocation process by notifying the permit holder. The states have varying retrieval processes, and 3 of them have authority to impose a penalty for failure to surrender a revoked permit or continuing to possess one. Law enforcement in the 9 case study states that issue permits told GAO that when encountering permits, such as during routine traffic stops, they visually check them and can take additional steps, such as checking state databases, as needed, to determine whether the permits are current and valid.
