Sorry to drag this back to the top but…

Thanks Mr. V! So 2-REG will allow for 999 registrations! 🙂

If there (as I believe there are!) are 26 letters in the standard alphabet then that (if we leave them all in, is there any need to dump Q for looking like O these days when phonetically they don’t sound the same anyway?) gives 17,576 individual registrations in a 123 format and 456,976 individual registrations in a 1234 format.

Just think yourselves lucky they haven’t yet decided to go over to a barcode on the side…
