How to cancel Ethias by mail
Collect the details you need
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Ethias can only act on a request it can match to an account.
Put the request in writing
Because Ethias 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.
Post the letter
Address the envelope to Ethias, Liège, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the proof of delivery
Delivery confirmation is your evidence that Ethias was asked. Watch the next statement or two for any further Ethias charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Ethias cancellation letter goes
Ethias lists Rue des Croisiers 24, Klantendienst Ethias, afdeling Klantendienst, 4000 Liège, Belgium as its mailing address.
Copy the postal code 4000 exactly: it is what routes the letter to Région wallonne, Belgium.
The letter is addressed “À qui de droit,” and its details block uses the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Ethias, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
