Yes, this is what Chrysler calls a fendertag. There should also be one riveted to the floor of the tub between the driver's seat and the door--look under your carpet. In the case of the TJ, the fendertag on the tub is the "full" tag; the one on the cross member doesn't have quite as much information.
The fendertag is used on the assembly line to indicate some
of the major features and options of the vehicle. For example, your fendertag tells me your Jeep is black (PX8) with the 4.0L engine (ERH) and has air conditioning (HAA). It tells me even more than this, but it is difficult to read due to all the rust.
