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.
