How to cancel Radar by mail
Collect the details you need
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Radar names the right account the first time.
Draft the request
Because Radar is dealt with in Dutch, the letter is written in Dutch (template nl). Subject: “Onderwerp: annuleringsverzoek – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Send the letter by certified mail
Post it by certified mail to Radar in Amsterdam, Netherlands, using the exact address below, and note the tracking number.
Keep proof the letter arrived
It shows the date Radar received your letter. Check your next statement: no Radar charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Radar cancellation letter goes
The mailing address we hold for Radar is Postbus 1431, 1000 BK Amsterdam, Netherlands.
“Postbus 1431” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
The letter is addressed “Geachte heer/mevrouw,” and its details block uses the labels Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Before you cancel Radar, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
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.
