One place for Sosh's mailing addresses: the Lille 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

The France address on file for Sosh. Postal code 59878.

How to address the envelope

  1. Write the address as printed

    Write out TSA 10018, TSA 10018, 59878 Lille, France as shown above, including the 59878 postal code, exactly as printed.

  2. Put your own address on it

    Your name and postal address go top-left on the front (or the back flap). If the letter cannot be delivered it comes back to you, which is itself evidence of the attempt.

  3. Send it certified

    Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Lille is traceable from the article number until it is signed for.

  4. Keep what the post office gives you

    The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.

The letter to send

Copy the letter below onto one page, fill in the account number, the phone number or service address being cancelled and the name on the account, and it is ready for the envelope. Our template builds the same letter on screen.
