Copy of GMRS and FRS channels/frequencies chart for your reference.

The FCC requires a GMRS radio license as a way to regulate frequencies that are used by two-way radio devices.

Here is a link to the Midland USA site that explains the process.

Portable and mobile radios fall into four categories:

• HAM

• CB (citizens band)

• GMRS (general mobile radio service)

• FRS (family radio service)

• Race radio (specially licensed business frequencies)

In addition to the 22 primary GMRS channels, it is possible to program special sub-tones within a channel in order to achieve a modicum of privacy.

There is a large misnomer regarding how this “privacy” thing operates. It does mean that other radio listeners on the same primary channel cannot hear you; it only means that your radio will only hear other radio transmissions encoded similarly to yours.
