How to cancel National Academic 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. National Academic can only act on a request it can match to an account.
Prepare the letter
Postbye writes the letter in Dutch from our Dutch template, because National Academic's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks National Academic to end the subscription, stop all further charges and confirm in writing.
Post the letter
Post it by certified mail to National Academic in Dordrecht, Netherlands, using the exact address below, and note the tracking number.
Hold on to the receipt
It shows the date National Academic received your letter. Check your next statement: no National Academic charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your National Academic cancellation letter goes
National Academic lists Postbus 362, 3300 AJ Dordrecht, Netherlands as its mailing address.
“Postbus 362” 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 greets the reader with “Geachte heer/mevrouw,”; your own details sit under the labels Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Before you cancel National Academic, check these
- 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.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.

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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
