Who does your GTX330 report your N number to?

I don't think they do directly report the N number, but doesn't the
installer-coded Mode S octal code get downllinked to ATC whenever a
mode-s enabled ground interrogator paints it, regardless of the unit's
user-selectable "flight id" or 4096 code setting, thus effectively
downlinking the N number because of a trivial database lookup?
