1 How to find and use the Klarna customer service number

Overview and why the number matters

Klarna is a global payments provider founded in 2005 with its corporate headquarters in Stockholm (Sveavägen 46, SE‑111 34 Stockholm, Sweden; Klarna AB, org. nr. 556737‑0431). Because Klarna offers country‑specific products (for example “Pay in 30”, “Pay in 4/Pay in 3” instalments and longer term financing), customer service is delivered locally: phone numbers, opening hours and escalation paths vary by market. That means the single “global” phone number is not useful for resolving purchase, refund or invoice issues tied to a merchant in a particular country.

Practically, the customer service number is typically used for time‑sensitive tasks: disputing a charge, confirming that a merchant has issued a refund, stopping a payment, or getting a firm repayment schedule for a financing product. For issues that involve a specific merchant transaction, Klarna will always ask for order IDs, merchant references and dates — having those to hand speeds resolution and reduces hold time.

Where to find the official, current customer service number

Because phone details are updated frequently, the most reliable sources are Klarna’s country help pages and the Klarna mobile app. The app ties your account, invoices and orders to the correct local support channel and generally shows the exact telephone number, call scheduling options, and estimated wait time for your account and product type.

Use these direct help pages to confirm numbers and hours (these pages also include chat, email and postal contact options):

United States: https://www.klarna.com/us/customer-service/ — use the app for the fastest phone routing and case logging.

United Kingdom: https://www.klarna.com/uk/customer-service/ — shows phone, chat and postal details for UK products.

Sweden: https://www.klarna.com/se/kundservice/ — corporate office: Sveavägen 46, 111 34 Stockholm; Klarna AB, org.nr 556737‑0431.

Germany: https://www.klarna.com/de/kontakt/ — local numbers and a business customer channel.

What to prepare before you call (essential checklist)

Preparing the right documentation before calling will dramatically reduce time on the phone and improve chances of a favorable outcome. Klarna agents require transaction-level data to link your query to the merchant’s settlement: merchant name, purchase date, item price, Klarna order ID or invoice number, and the last four digits of the card used (if applicable).

Required items: Klarna order ID (e.g., ord_123456), invoice/reference number, merchant name, purchase date, amount paid or due (e.g., $49.99 on 2024‑06‑15), and your Klarna account email/phone.

Optional but helpful: merchant confirmation emails, tracking numbers for returned goods, screenshots of merchant refund confirmations, and bank statements showing the Klarna transaction.

How agents use that information

When you provide the order ID and merchant information, the agent will locate the transaction in Klarna’s ledger and check settlement status with the merchant acquirer. For refunds, Klarna will confirm whether the merchant issued a refund and provide an expected credit timeline — typically 3–14 business days depending on the merchant and the customer’s bank. For invoice disputes Klarna documents your complaint and may place a temporary “dispute” hold on collection while the merchant investigation proceeds.

Record the agent’s name, case reference number and the expected resolution time before you end the call. If the agent provides a case or ticket number, save it: you will need it for follow‑ups and for escalation to Klarna’s complaints department or financial ombudsman if necessary.

What to expect on the phone and alternative channels

Typical hold times vary by country and time of year. Outside peak shopping periods, expect 5–20 minutes; during seasonal peaks (Black Friday, year‑end sales) wait times can extend to 30–60 minutes. Many customers report faster resolution via the in‑app chat because it preattaches order data to the conversation. If you need immediate action (stop a payment, freeze a pending charge), call; for documentation or non‑urgent queries, use chat or email so you have written records.

Klarna also offers specific pathways for business customers and merchants. If you are a merchant, use the Klarna for Merchants platform and its dedicated business support portal (available through the same country help sections). For regulated complaints in the EU or UK, Klarna’s complaints procedure and contact details are available on its country pages and must be followed before referring a dispute to a financial ombudsman.

Common issues, timelines and escalation

Common calls to Klarna customer service involve refunds (merchant issued refund but not visible on account), billing disputes (wrong amount or duplicate charge), returns (merchant has not acknowledged receipt), and account or identity questions. Refunds issued by merchants typically take 3–14 business days to appear in your bank/card account after Klarna processes the credit; internal Klarna adjustments to invoices can appear faster (1–5 business days) depending on the payment method.

If a problem is unresolved after the timeframe given by the agent, escalate: ask for a supervisor or request a formal complaint number. Keep copies of all correspondence; in the EU you have statutory consumer rights (e.g., 14‑day right of withdrawal for many distance sales) and the ability to contact your local financial ombudsman. Klarna’s country pages list the specific ombudsman or regulatory body for that jurisdiction.
