How to cancel Challenges by mail
Gather your account details
Before writing, collect the email on the account, the delivery address for print copies and the subscription or reference number from your latest invoice. Challenges can only act on a request it can match to an account.
Set out the request
Postbye writes the letter in French from our French template, because Challenges's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Challenges to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Address the envelope to Challenges, Chantilly, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
Delivery confirmation is your evidence that Challenges was asked. Watch the next statement or two for any further Challenges charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Challenges cancellation letter goes
For a letter to Challenges, use Avenue du Général Leclerc 45, 60500 Chantilly, France.
Copy the postal code 60500 exactly: it is what routes the letter to Hauts-de-France, France.
Your name, address and email appear in a short block labelled Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, under the greeting “À qui de droit,”.

Cancelling a news or magazine subscription
Publishers often move you from an introductory price to the standard rate and can steer cancellations towards phone or chat, so a written request is the record that you asked.
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.
