How to cancel Csif by mail
Find your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Csif has on file.
Draft the request
Because Csif is dealt with in Spanish, the letter is written in Spanish (template es). Subject: “Asunto: Solicitud de cancelación – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Send it by certified mail
Mail the letter by certified mail to the Madrid address in the next section, and keep the tracking number.
Keep the proof of delivery
Once the letter is delivered, the date on the receipt is the date Csif 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 Csif cancellation letter goes
Csif lists Calle de Fernando el Santo, 28010 Madrid, Spain as its mailing address.
Madrid is the delivery town, Spain; the postal code to quote is 28010.
The letter is addressed “A quien corresponda,” and its details block uses the labels Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado.

Before you cancel Csif, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
