The addresses we hold
One place for Challenges's mailing addresses: the Chantilly 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
ChallengesAvenue du Général Leclerc 4560500 ChantillyFranceThe France address on file for Challenges. Postal code 60500.
How to address the envelope
Write the address as printed
Address the envelope to Avenue du Général Leclerc 45, 60500 Chantilly, France. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.
Add your return address
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.
Buy the certified service
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.
Keep the records
The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.
The letter, written out
What the letter to Challenges says: one clear cancellation request, no reasons given, the email on the account, the delivery address for print copies and the subscription or reference number from your latest invoice quoted, and a request for written confirmation.
