I hope RobW doesn't mind me quoting an email he sent me recently while
we were discussing this:

A bit more investigation, and asking someone who's in the know,
suggests that these suffixes correspond to boxes that are being
emptied by postmen on the rounds, and so have earlier collection times
than normal. Royal Mail made this change for boxes with low volumes of
mail where there's another box nearby with later collection times. I
believe that the base box number will be unchanged, so it's just a
case of a D being added to the end.

I've written a bit about this at

I've also updated my tools, so they'll ignore a "D" suffix if present
-- and so any D boxes will still match the original number that's on
Royal Mail's records.
