How to cancel Institut Pasteur by mail
Collect the details you need
You will need your donor or supporter number, the name on the donation and the amount and date of the latest payment. Use exactly the details Institut Pasteur holds, so the request can be matched to your account.
Write the cancellation request
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Mail it with tracking
Mail the letter by certified mail to the Paris address in the next section, and keep the tracking number.
Keep the delivery receipt
The receipt dates your request. Look at your next statement for any Institut Pasteur charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

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