We currently do not carry any radios of this type.

The Family Radio Service (FRS) is an improved walkie talkie system authorized in the United States since 1996. This personal radio service uses frequencies in the ultra high frequency (UHF) band, (462/467MHz) and so does not suffer the interference effects found on citizens\' band (CB) at 27 MHz, or the 49 MHz band also used by cordless phones, toys, and baby monitors. FRS uses frequency modulation (FM) instead of amplitude modulation (AM), and has a greater reliable range than license-free radios operating in the CB or 49 MHz bands.

FRS radios are limited to 500 milliwatts in the U.S., according to FCC regulations. Channels 1 to 7 are shared with GMRS, the General Mobile Radio Service. A license is required for those channels only if the power output is over FRS limits, up to GMRS limits.

Similar services in other countries
Services similar to the American FRS exist in other countries, although since technical standards and frequency bands may differ, usually FCC-approved FRS equipment may not be used in other jurisdictions.

American-standard FRS radios have been approved for use in Canada since April 2000. The revised technical standard RSS 210 has essentially the same technical requirements as in the United States. Since September 2004 low-power GMRS radios and dual-standard GMRS/FRS radios have also been approved for use in Canada, giving additional channels.

Since tourists often bring their FRS radios with them, and since trade between the U.S., Canada, and Mexico is of great value to all three countries, the Mexican Federal Telecommunications Commission has authorized use of the FRS frequencies and equipment similar to that in the US. However, dual-mode GMRS/FRS equipment is not approved in Mexico, so caution should be exercised in operating FRS devices purchased elsewhere.

In Europe, a personal radio service with the same sort of licensing restriction is PMR446 having eight channels in the 446MHz range. One cannot legally use the FRS radio in Europe or PMR446 in the U.S. The 446 MHZ band is allocated to amateur radio in the United States, so in principle a licensed amateur operator could use non-FCC-type-accepted PMR446 radios in the U.S. in compliance with the rules for amateur radio operation. In Great Britain FRS frequencies are used for fire brigade communications and this sometimes causes problems when FRS equipment is imported from the U.S. and used without awareness of the consequences by members of the public.

Dual-mode GMRS/FRS equipment is approved in Brazil and most South American countries. Portable radios are heavily used in private communications, especially by security staff in nightclubs and shopping centers, but also in private parking, maintenance and delivery services.

A service similar to the American-style FRS in Hong Kong, is called Short Range Portable Radio (SRPR), Macau and China is also approved by respective organizations for legal license-free operation. However, different UHF frequencies with 20 allocated channels near 409 MHz are used. 462 MHz and 446 MHz band are not opened to FRS service, so European, U.S. and Canada residents are advised not to use FRS or PMR446 radios for communication when traveling to the mentioned areas.

In Japan, a similar service uses low-power in the 420, 421, 422 MHZ bands. In Australia and New Zealand, the UHF CB citizens band near 477 MHZ is used for a similar purpose.
