How to cancel Sfr by mail
Find your account details
Sfr will look your account up from what the letter says, so check the account number, the phone number or service address being cancelled and the name on the account first.
Set out 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 Sfr to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Send it certified to Lyon, France, copying the address from the next section letter for letter, and keep the receipt slip.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Sfr was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Sfr cancellation letter goes
For a letter to Sfr, use TSA 30103, 69947 Lyon, France.
“TSA 30103” 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.
The letter greets the reader with “À qui de droit,”; your own details sit under the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
