How to cancel Humanitas by mail
Note your account details
Have your donor or supporter number, the name on the donation and the amount and date of the latest payment to hand. The details in the letter need to match what Humanitas has on file.
Write your request
Humanitas is based in Netherlands, so the letter goes out in Dutch, built from our Dutch template. Subject line: “Onderwerp: annuleringsverzoek – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail the letter with a receipt
Post it by certified mail to Humanitas in Amsterdam, Netherlands, using the exact address below, and note the tracking number.
Keep proof the letter arrived
It shows the date Humanitas received your letter. Check your next statement: no Humanitas charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Humanitas cancellation letter goes
Humanitas can be reached by post at Postbus 71, 1000 AB Amsterdam, Netherlands.
“Postbus 71” 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.

Cancelling a regular donation
Regular donations run until the donor ends them, so a written request should give the donor reference and ask the charity to stop the payment and confirm the end date.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
