How to cancel Waternet by mail
Start with your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Waternet is the easiest one to set aside.
Prepare the letter
Postbye writes the letter in Dutch from our Dutch template, because Waternet's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks Waternet to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Address the envelope to Waternet, Amsterdam, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the proof of delivery
File the receipt with the letter. A Waternet charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Waternet cancellation letter goes
The mailing address we hold for Waternet is Postbus 94370, 1090 GJ Amsterdam, Netherlands.
“Postbus 94370” 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.
Inside, the salutation reads “Geachte heer/mevrouw,”, followed by your details under Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Before you cancel Waternet, 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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
