Rule Part

47 C.F.R, Part 90

Radio Service Code(s)

  • GS - Exclusive Channels
  • IG - Shared Industrial/Business Channels
  • PW - Shared Public Safety Channels

A private paging service is a paging service that is not-for-profit and that serves the licensee's internal communications needs as defined in Part 90 of the Rules. Private paging systems in general provide the same applications offered by commercial paging services: tone, tone-voice, numeric or alphanumeric, shared-use, cost-sharing, or cooperative arrangements, multiple licensed systems that use third-party managers, or users combining resources to meet compatible needs for specialized internal communications facilities are presumptively private paging services.


The following frequencies are available to all Public Safety and Industrial Business Pool licensees for one-way paging on a shared basis:
  • 929.0375 MHz
  • 929.0625 MHz
  • 929.0875 MHz
  • 929.1625 MHz
  • 929.2625 MHz
Specific regulations governing the use of these bands can be found at 47 CFR 90.494.


Frequency Coordinator

In 1982, Congress provided the Commission with the statutory authority to use frequency coordinators to assist it in developing and managing the Private Land Mobile Radio (PLMR) spectrum.
Frequency coordinators, in this case, are private organizations that have been certified by the Commission to recommend the most appropriate frequencies for applicants in the designated Part 90 radio services. This frequency coordination process is intended to make more efficient use of the PLMR spectrum for the benefit of all members of the public.
In general, applications for new frequency assignments, changes to existing facilities or operation at temporary locations must include a showing of frequency coordination. See 47 CFR 90.175 for further information.
