How to cancel Boursobank by mail
Note your account details
Before writing, collect the account email, the last four digits of the linked bank account or card and the membership tier. Boursobank can only act on a request it can match to an account.
Write your request
Boursobank is based in France, so the letter goes out in French, built from our French template. Subject line: “Objet : Demande d'annulation – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail the letter with a receipt
Address the envelope to Boursobank, Trappes, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
File the delivery record
Delivery confirmation is your evidence that Boursobank was asked. Watch the next statement or two for any further Boursobank charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Boursobank cancellation letter goes
Boursobank lists TSA 80010, 78199 Trappes, France as its mailing address.
“TSA 80010” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
Inside, the salutation reads “À qui de droit,”, followed by your details under Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Boursobank, check these
- Settle any outstanding balance first. Closing a membership does not clear what you owe.
- Ask for the direct debit or card authorisation to be ended, not only the membership.
- Investment and credit-builder products can have their own steps for closing the underlying account.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
