Obtaining your FCC license for GMRS
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.
CB or GMRS
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)

PL or Tone Squelch is not private
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.
