How to cancel Nkc by mail
Collect the details you need
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Nkc can only act on a request it can match to an account.
Draft the request
Postbye writes the letter in Dutch from our Dutch template, because Nkc's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks Nkc to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Use certified mail for the 3760 AK Soest address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the delivery receipt
Delivery confirmation is your evidence that Nkc was asked. Watch the next statement or two for any further Nkc charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Nkc cancellation letter goes
The mailing address we hold for Nkc is Postbus 424, 3760 AK Soest, Netherlands.
“Postbus 424” 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.
Your details go in a block headed by Accounthouder, Factuuradres in dossier and E-mailadres in dossier, and the opening line is “Geachte heer/mevrouw,”.
Prefer to write it yourself? Use our letter template
Before you cancel Nkc, check these
- 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.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
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.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
