How to cancel Ocs by mail
Gather your account details
Check the email address on the account, the plan name and, if you can find it, the billing partner shown on your latest statement before anything else. A request that does not match the account on file at Ocs is the easiest one to set aside.
Draft the request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Ocs to close the subscription, stop billing and confirm in writing.
Post the letter
Send it certified to Issy-les-Moulineaux, France, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
Keep the tracking record with your copy of the letter. If Ocs 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.
Where your Ocs cancellation letter goes
Ocs takes its post at Quai du Président Roosevelt 111, 92130 Issy-les-Moulineaux, France, which is where a cancellation letter belongs.
Copy the postal code 92130 exactly: it is what routes the letter to Île-de-France, France.
Your details go in a block headed by Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, and the opening line is “À qui de droit,”.

Before you cancel Ocs, check these
- Check the billing date on your statement and send the request well before it, so the cancellation lands inside the current period.
- If an app store, phone carrier or TV provider bills you, the service itself cannot cancel it. Cancel with the billing partner as well.
- Access normally runs to the end of the period you paid for, so a cancellation does not shorten what you already bought.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a streaming or entertainment subscription
Streaming plans renew silently each month, and many are billed by a partner such as an app store or a TV provider rather than the service itself, so the request has to reach whoever actually bills you.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
