Legal & Sources

Data sources

The frequency data on Find Routing is compiled from publicly published sources:

  • NIFOG (National Interoperability Field Operations Guide) — published by the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) through the SAFECOM program. NIFOG is the canonical reference for nationwide public-safety interop channels and is freely distributed by the federal government. cisa.gov/safecom/field-operations-guides
  • State public-safety interop plans — published by state interoperability coordinators and emergency management agencies. We list state-specific mutual aid channels (CALCORD, OSCCR, MABAS Red, NJICS, CMED, MEMSCOM, and others) drawn from these public documents.
  • Common US public-safety channel plans — for the representative county dispatch entries, frequencies are selected from common channel plans in the public-safety VHF, UHF, and 800 MHz bands. These are intended to give scanner programmers a reasonable starting point and are clearly marked. Confirm exact in-use assignments with the licensing agency or a current entry in a comprehensive database such as RadioReference before relying on them operationally.

Accuracy

Public-safety radio plans change constantly: agencies migrate to trunked systems, jurisdictions consolidate dispatch centers, and channel assignments are reshuffled in response to interference and licensing changes. We do our best to reflect the published nationwide and state plans, but we make no warranty as to current operational accuracy. If you find an error, contact us through the operator listed on this page and we will correct it.

Acceptable use

In the United States, monitoring public-safety radio traffic is generally lawful under federal law (47 USC §605 and the Communications Act). Some states impose additional restrictions on the use of scanner information — for example, prohibiting the use of a mobile scanner in a vehicle in furtherance of a crime. Find Routing does not publish encrypted-system keys, system master files, or anything that would help defeat lawful encryption. You are responsible for knowing the law in your jurisdiction.
