No, you won't need to re-register.
If you think your credit card's lost, stolen, damaged or you don't recognise a transaction, please let us know as soon as possible by calling 03456 062 062 (or 0044 1244 659005 from outside the UK). If you're calling from abroad, please place the call through the international operator.
We'll send you a new card with a new account number which you can activate online, and a new account will show in your existing Online Card Services within a few days. If you’ve added your credit card details to a mobile device so you can make payments, you’ll need to update those details when your new credit card arrives. If you have monthly subscriptions set up on the account, please update them with your new account details too.
Check out our security page to find out more about keeping your card and account details safe.
