Re: [Talk-GB] Kent County Council Highways Gazetteer
No idea whether c-class road references are nationally unique. It seems both plausible and implausible at the same time. The C-numbers seem to low (1000) for them to be national. You'd probably end up with 6-figure C roads if they were nationally numbered... Also Kent isn't in region 3 for road numbering (between the A3 and A4, i.e. Wessex and southwest England) which would mean it's unlikely to be a national scheme.

Re: [Talk-GB] Kent County Council Highways Gazetteer
If this information is available then its useful data within OSM in the same way that references to gritting routes and customary bus stops are useful. However, because these things are difficult or impossible to verify on the ground its doubly important that if they are added to the database they include appropriate source tagging. I certainly would not encourage changing the highway= tag just because the local authority has referenced the road as C, D or U. Just treat the detail as additional useful information to someone, not necessarily the OSM rendered map.

I don't believe they are - in fact each authority has it's own numbering scheme for such roads. Some just use Cxxx, some use Cxxx and Dxxx, some use Uxxx and so on. At the top of the KCC Gazetteer it says: National Convention for Road Numbering: `U' stands for `Unclassified' `P' stands for `Private Street' So it appears there is a national convention, implying that authorities are not obliged to follow it. It might exist as a formal document, but it might be just a de facto convention. Uxxx appears to mean explicitly unclassified whereas a Cxxx or Dxxx road is not unclassified - it's a C-road or a D-road.

Re: [Talk-GB] Kent County Council Highways Gazetteer
[Snip] A couple of questions about C-roads... Is there a consensus about how these should be treated? Given that they are not a 'public-facing' classification (never appear on road signs or on any map you would buy from W. H. Smith's), I'm not sure we want the standard renderings cluttered up with them, do we? Should we invent a tag such as ref:internal (say) for these? No. That would be tagging for the renderer. Even if it's generally a non-visible ref in the outside world (though I've seen three C-roads leak onto signs in my travels) I believe that it's the render's choice as to whether they should show up on the maps, not for us to say that there's something special about the fact. A fact's a fact. Secondly, am I right in thinking that these are not unique references like the A- and B-roads? (Unique within the UK, that is.) In other words, whereas Wrotham Road near me is 'the A227', nearby Coldharbour Road is not 'the C364', it's just one of many C364s, albeit the only one in Kent? Should this be reflected in the tagging? I see in the States they use network=US:[state]:[county] to tag county roads. I'm not sure whether they're nationally unique references, but they'll be unique per authority and we've got pretty good bounding areas for those in OSM now.
