Another lost New Zealand favourite for Housie books that we are re-introducing.
All tickets in any of our Housie books carry the SAME BOOK NUMBER.
In this way it is clearly understood that a given ticket (either still bound in one of your Housie books or detached) belongs to the specified book number.
By viewing the serial number we also know that it comes from a certain series of a particular book type. Along with the game number, we even know the position of the ticket in that book.
Add to that the serial number and you have everything you need to determine with certainty that it was either sold by you or it is a fraudulently introduced and unpaid for ticket.
