How to cancel Suez by mail
Collect the details you need
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Suez 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.
Mail it with tracking
Address the envelope to Suez, Courbevoie, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Save the tracking record
File the receipt with the letter. A Suez 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.
Where your Suez cancellation letter goes
The mailing address we hold for Suez is Place de l'Iris 16, 92400 Courbevoie, France.
The postcode 92400 belongs to Île-de-France, France, so this is where the envelope is delivered.
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 Suez, check these
- 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.
- Use the same name and email as on the account. A mismatch can delay the request.
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.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
