How to cancel KBC by mail
Get your account details together
You will need the account email, the last four digits of the linked bank account or card and the membership tier. Use exactly the details KBC holds, so the request can be matched to your account.
Write the cancellation request
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Post it with proof of delivery
Send the letter to the Leuven mailing address shown below by certified mail. Keep the tracking number safe.
File the delivery record
Keep the tracking record with your copy of the letter. If KBC bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel KBC, check these
- Investment and credit-builder products can have their own steps for closing the underlying account.
- Check your bank statement after the cancellation date for any further charge.
- Settle any outstanding balance first. Closing a membership does not clear what you owe.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
