How to cancel Diners Club by mail
Collect the details you need
Diners Club will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Put the request in writing
Because Diners Club is dealt with in Italian, the letter is written in Italian (template it). Subject: “Oggetto: Richiesta di cancellazione – [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 Milano address in the next section, and keep the tracking number.
Keep the proof of delivery
It shows the date Diners Club received your letter. Check your next statement: no Diners Club charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Diners Club cancellation letter goes
For a letter to Diners Club, use Via Roberto Lepetit 8, 20124 Milano, Italy.
Copy the postal code 20124 exactly: it is what routes the letter to Lombardia, Italy.
The letter greets the reader with “A chi di competenza,”; your own details sit under the labels Titolare dell'account, Indirizzo di fatturazione registrato and Email registrata.

Before you cancel Diners Club, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
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.
