Other Easy Ways to Get Help

Of course, phone support isn’t the only option. Klarna actually encourages users to reach out through other channels that may be even quicker.

1. Support Through the Klarna App

If you have the app, this is usually the fastest way to get help. Just open the app, go to Profile → Customer Service, and you’ll find options for live chat and FAQs. Many users say chat support solves problems faster than phone calls.

2. Live Chat on Klarna’s Website

Don’t have the app? No problem. Visit klarna.com, scroll to the help section, and use the chat feature. It connects you with a real agent within minutes.

3. Email Support

For issues that aren’t urgent, you can always email Klarna. In the U.S., the email is customerservice@klarna.com. If you’re outside the U.S., you’ll find region-specific emails on their site. Email is great when you need to attach screenshots or receipts.

4. Social Media Help

Klarna is also active on Twitter, Facebook, and Instagram. While they won’t solve account-related issues directly on social media, they do respond quickly and guide you to the right support channel.

Tips to Get Faster Help

Here are a few small things you can do to save time when contacting Klarna:

  • Always check the app first—it has built-in support and FAQs

  • Keep your order number, payment date, and account email ready

  • Use chat for quick fixes, phone calls for urgent issues, and email for detailed queries

  • Stay polite and clear while explaining your issue—it helps agents respond faster

Support Availability

  • Phone Support: Business hours (varies by country)

  • Live Chat (App & Website): Usually available 24/7

  • Email: Replies typically come within 1–2 business days

So if your issue can’t wait, chat or call is the way to go.

Final Thoughts

Klarna has made online shopping easier with its flexible payment options, but no service is perfect. Sometimes payments fail, refunds take longer, or accounts get tricky. Luckily, Klarna’s support system is designed to help you quickly.
