How do I block my card in case of fraud or loss?

If you have lost your card or noticed a transaction on your account for which you are not responsible, we advise you to block your card.

Blocking your card is permanent. You will no longer be able to perform transactions with this card and you won't be able to reactivate it. However, your account will remain open.

To block your card, go to your web Customer Area or your Nickel Application:

  • Click on the "Card" tab
  • Under the "Security" section, click on "BLOCK MY CARD"
  • Choose the reason for blocking your card: fraudulent card, lost card or stolen card. 
  • Confirm the blocking.

If you cannot access your web Customer Area or your Nickel Application:

  • Call the opposition center at 01.76.49.48.10 (open 7 days a week, 24h/24) or from abroad at +33.01.76.49.48.10 
  • Type your phone number
  • Confirm the blocking of the card

You can also contact Customer Service at  01 76 49 00 00 to block your card.

To replace your Nickel card afterwards, consult this article.

Blocking your card does not automatically close your account. You can still use Nickel services to pay and be paid. Future direct debits and contributions will be debited from your account.
