How to cancel 11 11 11 by mail
Gather your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. 11 11 11 can only act on a request it can match to an account.
Put the request in writing
Because 11 11 11 is dealt with in French, the letter is written in French (template fr). Subject: “Objet : Demande d'annulation – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail the letter with a receipt
Mail the letter by certified mail to the Saint-Gilles address in the next section, and keep the tracking number.
File the delivery record
File the receipt with the letter. A 11 11 11 charge dated after delivery is the one to dispute, and these two documents are what you quote.

Before you cancel 11 11 11, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- 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.
