How to cancel Klarna by mail
Start with your account details
Klarna will look your account up from what the letter says, so check the account email, the last four digits of the linked bank account or card and the membership tier first.
Write your request
Because Klarna is dealt with in Swedish, the letter is written in Swedish (template sv). Subject: “Ämne: Begäran om uppsägning – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail the letter with a receipt
Take the letter to the post office and ask for certified delivery to 111 34 Stockholm. Keep the tracking number it gives you.
Hold on to the receipt
It shows the date Klarna received your letter. Check your next statement: no Klarna charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Klarna cancellation letter goes
Written requests to Klarna go to Sveavägen 46, 111 34 Stockholm, Sweden.
Stockholm is in Stockholm County, Sweden; the postal code to quote is 111 34.
The database also lists Via Giuseppe Mazzini 9, 20123 Milano, Italy for Klarna. Use the first address above unless your agreement names this one.
Inside, the salutation reads “Till berörd part,”, followed by your details under Kontoinnehavare, Registrerad faktureringsadress and Registrerad e-postadress.

Before you cancel Klarna, check these
- Settle any outstanding balance first. Closing a membership does not clear what you owe.
- Ask for the direct debit or card authorisation to be ended, not only the membership.
- Investment and credit-builder products can have their own steps for closing the underlying account.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
