We require the ISP email in order to provide a mechanism to authenticate some orders that our fraud prevention software will identify as higher risk orders. Our fraud prevention system protects us and you from unauthorized purchases being made with stolen credit cards.

Register4less.com uses a rule database which assesses the risk of credit card transactions. Based on these factors, further verification may be required to approve the transaction. While we try to keep this type of verification as easy for you as we can, please consider that this helps us keep our prices as low as possible.
