What is the Klarna customer service number?

Short answer — there is no single global number

Klarna does not operate a single universal customer service telephone number that works for every country and every kind of inquiry. Instead, Klarna routes support by country, product (Pay Later, Pay in 30, installment plans, merchant support) and by channel (in-app chat, web help center, phone callback). This structure is deliberate: Klarna serves customers in multiple currencies and legal jurisdictions, so the fastest and most accurate contact method is the country-specific contact information published in the Klarna app and on the help site.

If you need a direct phone conversation, the practical approach is to open the Klarna app or visit the official help portal at https://help.klarna.com — those two entry points show the exact phone numbers, call-back options and hours for your country and for the particular product tied to your order or account. Klarna’s corporate HQ is Klarna Bank AB (publ), Sveavägen 46, 111 34 Stockholm, Sweden, founded in 2005; as of 2023 Klarna reported serving approximately 147 million consumers across about 45 markets, which explains why support is localized.

Why Klarna uses localized phone numbers and in-app support

Localization reduces handling time and regulatory risk: customers calling a local number reach agents trained for that market’s consumer protection rules, currencies and common merchants. For example, chargeback and dispute processes differ between the United States, the UK, Germany and Sweden. Operators therefore provide different scripts, hold times and escalation paths — which is why a single global hotline would be inefficient and could lead to incorrect advice.

Klarna also invests in asynchronous channels: the in-app chat and the web help center (https://help.klarna.com) are designed to resolve many issues without a voice call. In practice, Klarna’s in-app messaging often provides verification steps, links to invoices, payment scheduling and direct escalation to specialists; industry benchmarks indicate that in-app and chat-first strategies reduce average handling time and increase first-contact resolution for digital-native fintechs.

How to find the correct Klarna customer service number (step-by-step)

• Open the Klarna app (iOS / Android): Tap Profile → Get Help or the chat icon. The app will display the phone callback option if voice support is available for your issue and country. Use the “Request callback” feature to avoid queue time and to ensure the agent sees your account context.
• Visit the official help site: go to https://help.klarna.com, select your country in the top-right (or the country selector), then search for “contact” or “phone number.” The help pages list hours and alternative channels (chat, email forms, merchant dispute forms).
• Check the invoice or order confirmation email: Klarna invoices and order confirmations often include a country-specific support link or phone number connected to that transaction, especially for Apple/Google/merchant-initiated purchases.
• For business or merchant support: use https://www.klarna.com/business where business phone and account manager contacts are provided; merchant SLAs and contract numbers are handled through separate business channels.

Practical details and what to prepare before you call or chat

To expedite any Klarna support interaction, have the following ready: your Klarna account email or phone number, the order number or Klarna invoice number, the merchant name, transaction date, the last four digits of the payment method and a brief description of the problem (refund not received, incorrect amount, delivery dispute, suspected fraud). These items let the agent locate the transaction quickly — average successful resolution in chat is typically under 20 minutes for straightforward billing queries when full information is provided.

If the issue is fraud or a lost/stolen payment card, call your bank immediately to block the card and then use the Klarna app to report the transaction. Klarna will usually request a dispute form and documentation from you; having proof of non-delivery, tracking numbers or photos will speed an investigation. For legal or escalation cases, note that Klarna’s data center and case logs are timestamped in local time for the market handling your account.

When you should call versus when the app or web help is better

Call (or request a callback) when the issue is time-sensitive or requires a human decision: suspected fraud, card blocking, immediate payment plan adjustments, or escalations where previous chat attempts didn’t resolve the issue. Phone callbacks are best when waiting time is acceptable and you need clarification on repayment obligations — for example, to confirm a payment schedule or agree a one-off deferral.

Use the app/chat and help center for document uploads, invoice copies, scheduled changes and non-urgent inquiries. The help center includes self-serve options (reschedule a payment, download invoices, submit returns) that resolve most routine issues without a voice call. Always verify any phone number you find by cross-checking it with the app or https://help.klarna.com to avoid fraud or spoofing attempts.
