Resources such as RadioReference.com and InterceptRadio.com provide lists of police scanner frequencies aggregated from nationwide sources and FCC databases. Websites such as Broadcastify allow users to search for police scanner frequencies by state, city or zip code, and to listen live audio feeds online.
Online resources that provide police scanner frequencies from FCC databases require specific search queries due to the massive amounts of information they contain, explains Intercept Radio. Websites such as ScannerMaster.com can provide advice on how to narrow down search terms for ease of access. Because police scanner frequencies vary widely across the United States, many local governments post their frequencies online for the public to access.
