How to cancel Kpn by mail
Note your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Kpn is only as good as the details it quotes.
Put the request in writing
Because Kpn 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.
Mail it with tracking
Address the envelope to Kpn, Alphen Aan De Rijn, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Kpn charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Kpn cancellation letter goes
Written requests to Kpn go to Postbus 235, t.a.v. Opzeggen, 2400 AE Alphen Aan De Rijn, Netherlands.
“Postbus 235” 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 database also lists Wilhelminakade 123, 3072 AP Rotterdam, Netherlands for Kpn. Use the first address above unless your agreement names this one.
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 Kpn, check these
- 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.
- Check your next statement: no charge should appear after the cancellation date.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
