Additional data after Club des Actionnaires benefits were reduced to include Gold rather than Platinum status:
3081062 = Club des Actionnaires Platinum;
3081033 = Club des Actionnaires Gold.

zehbra reports that a move from CdA Platinum to 'standard' Platinum changed digits six and seven from 62 to 34. So it appears that 'special' numbers for CdA members may be a thing of the past.
