Your questions
about the opposition.
An emergency? Call directly on 0 800 000 000.
What is the difference between blocking and opposition?
The blocking is a temporary and reversible measure: you suspend your card while you find it. The opposition is a definitive legal act which irremediably cancels your card and triggers the issuance of a new one. To be used only in the event of loss or certain theft.
Am I responsible for fraudulent transactions before the opposition?
Your liability is limited to €50 for transactions without a PIN code carried out before opposition (European legal threshold). Beyond that, Nexia takes full care. If the loss/theft results from gross negligence on your part (e.g. PIN noted on the card), different conditions may apply — our team supports you on a case-by-case basis.
How much does it cost to object and issue a new card?
Opposition is completely free at Nexia, whatever your card type. The issuance of a replacement card is also offered for the first opposition per year. In the event of repeated opposition (from the 2nd per year), fees of €10 may apply.
Can I file an opposition if I am abroad?
Yes. The emergency number +33 9 00 000 000 (international rate) is accessible 24 hours a day from any country. The Nexia application also works without a French network. If this is not possible, dial the universal interbank number +33 892 705 705.
Is the opposition canceling direct debits?
No. SEPA direct debits (rent, EDF, subscriptions, etc.) are not affected by the opposition of your card, because they are linked to your IBAN and not to your card number. Only card payments (CB, Visa, NFC) are canceled. Your direct debits continue to operate normally.
My child has lost his card - should I, as a parent, object?
Yes. For a Nexia child or adolescent card, opposition must be requested by the legal representative holding the parent account. You can do this from your own Nexia space, “My cards” section → child’s card → “File opposition”. The new card is sent to your postal address.
