2 separate issues.
1) Is a VRP in the AIP?
2) Is a VRP visible?
If it is in the AIP then it should appear in the modern GPS databases. I did a VFR/Europe presentation the other week and for that I looked at some current Garmin handhelds (695 etc). All of them showed the official VRPs, as published on the Jepp printed charts for example.
As regards 2) that is an old chestnut - look at the notorious "Nokia Factory" near Farnborough
Actually, for all I know (not looking it up right now) that might well be an official VRP because IIRC my KMD550 shows it
But if you have a GPS which shows VRPs, 90% of the job is done for you.
In the international (Europe) VFR context, ATC will normally send you to a VRP, so you have to be on top of those which you can reasonably expect.
France tends to use 1- and 2-letter VRP names, such that ones to the N of the airport are called N, NA, NB, ones to the east are called E, EA, EB etc.
Some other countries also use single letter names but not based on the compass bearings e.g. LIPQ has VRPs called G or GRADO and V or VICKY to the south of the airport
