Where to send your Dokom21 cancellation letter

Read the addresses on this page next to the full guide to cancelling Dokom21.

The addresses we hold

One place for Dokom21's mailing addresses: the Dortmund delivery point for a cancellation letter first, then the rest of what the database holds, with envelope wording that matches.

Where the letter goesMailing address

Dokom21Stockholmer Allee 2444269 DortmundGermany

The Germany address on file for Dokom21. Postal code 44269.

How to address the envelope

  1. Copy the address exactly

    The envelope reads Stockholmer Allee 24, 44269 Dortmund, Germany. Match the spacing and the box or street line exactly as printed.

  2. Put your own address on it

    Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.

  3. Certified mail, not a courier

    Certified mail is bought at the post office: hand the letter to a postal employee, keep the postmarked receipt, and follow the article number until the delivery shows.

  4. File the receipt with your copy

    Hold on to the letter copy, the receipt and the tracking page.

The cancellation letter

What the letter to Dokom21 says: one clear cancellation request, no reasons given, the account number, the phone number or service address being cancelled and the name on the account quoted, and a request for written confirmation.
