so with Peter's comment in mind I entered the identifiers for some local US VRPs and confirmed that they're in the Foreflight GPS database, in this case running on my mobile phone. An interesting exercise and potentially useful for cross country because (strangely enough!) I've always used VRPs visually.
When I was preparing my VFR Europe presentation (here) I popped into a local pilot shop and all the current model Garmins had the European VRPs.
But only the official ones, which are found on the VFR charts. Locally used ones, e.g. the "power station chimney" or "the tunnels" used near Shoreham, would not be on there.
