How to cancel Numero by mail
Start with your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Numero is only as good as the details it quotes.
Draft the request
Because Numero 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 delivery receipt
Keep the tracking record with your copy of the letter. If Numero bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Numero cancellation letter goes
Written requests to Numero go to Paseo de la Castellana 91, 28046 Madrid, Spain.
The envelope is going to Madrid in Comunidad de Madrid, Spain, so the postcode 28046 must be on the front.
Inside, the salutation reads “A quien corresponda,”, followed by your details under Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado.

Before you cancel Numero, check these
- 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.
- Check your next statement: no charge should appear after the cancellation date.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
