How to cancel Telefonica by mail
Collect the details you need
You will need the account number, the phone number or service address being cancelled and the name on the account. Use exactly the details Telefonica holds, so the request can be matched to your account.
Set out the request
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Telefonica to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Mail the letter by certified mail to the München address in the next section, and keep the tracking number.
Keep the proof of delivery
Keep the tracking record with your copy of the letter. If Telefonica 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 Telefonica cancellation letter goes
Telefonica takes its post at Georg-Brauchle-Ring 50, 80992 München, Germany, which is where a cancellation letter belongs.
The postcode 80992 belongs to Bayern, Germany, so this is where the envelope is delivered.
The letter is addressed “Sehr geehrte Damen und Herren,” and its details block uses the labels Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
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.
