How to cancel Operation Smile by mail
Start with your account details
Before writing, collect your donor or supporter number, the name on the donation and the amount and date of the latest payment. Operation Smile can only act on a request it can match to an account.
Write the cancellation request
Postbye writes the letter in Swedish from our Swedish template, because Operation Smile's address is in Sweden. It opens with the subject line “Ämne: Begäran om uppsägning – [your name]” and asks Operation Smile to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 111 37 Stockholm. Keep the tracking number it gives you.
Hold on to the receipt
File the receipt with the letter. A Operation Smile 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 Operation Smile cancellation letter goes
The mailing address we hold for Operation Smile is Adolf Fredriks kyrkogata 10, 111 37 Stockholm, Sweden.
Copy the postal code 111 37 exactly: it is what routes the letter to Stockholms län, Sweden.
Inside, the salutation reads “Till berörd part,”, followed by your details under Kontoinnehavare, Registrerad faktureringsadress and Registrerad e-postadress.

Before you cancel Operation Smile, check these

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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
