How to cancel Karapass by mail
Find your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Karapass holds, so the request can be matched to your account.
Draft the 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.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 78330 Fontenay-le-Fleury. Keep the tracking number it gives you.
File the delivery record
File the receipt with the letter. A Karapass charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Karapass, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
