Klarna customer service contact number — complete practical guide

Overview: why precise contact details matter

Klarna, founded in 2005 in Stockholm, is a global payments provider servicing over 150 million consumers and more than 450,000 merchants across 45+ markets. Because Klarna offers a variety of products — “Pay now”, “Pay later”, instalments (Slice it), and merchant services — the correct contact number or channel depends on your country, product and whether you are a consumer or a merchant. Using the wrong number or generic help page slows resolution and can complicate disputes with merchants or lenders.

This guide gives clear, actionable steps for finding the correct Klarna contact number, explains what information to have before calling, lists the official channels, and highlights expected response times and escalation options. Where a single universal phone number exists (Sweden corporate line) it’s shown; for local customer support we point to the official regional pages and the in-app contact flow so you always get the right line for your issue.

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

The most reliable sources for a current, country-specific Klarna phone number are: the Klarna mobile app (profile → help → contact), the Klarna regional help centre, and the Klarna.com country pages. These methods automatically surface the right phone number for your account region, language and product. Using the app ensures agents can see your account context (order IDs, invoices) and speeds up resolution.

Direct links (type into your browser): Klarna global site — https://www.klarna.com. Regional help pages that list contact options include https://www.klarna.com/us/customer-service/ (United States), https://www.klarna.com/uk/customer-service/ (United Kingdom) and https://www.klarna.com/se/kundservice/ (Sweden). If you cannot access the app, the regional help centre pages will show local phone numbers and business hours.

Official corporate contact and head office address

For corporate or legal correspondence, Klarna Bank AB (publ) is headquartered in Stockholm. Official HQ (public) address used in filings and investor materials: Klarna Bank AB (publ), Sveavägen 46, 111 34 Stockholm, Sweden. The main Swedish switchboard (used for some official enquiries) is published as +46 8 120 120 10. For consumer problems, however, Klarna directs users to the app or local help pages so agents can access account-specific data.

Note: using the corporate switchboard for consumer account issues often results in redirection to the local customer support channels. Always confirm on the regional help page whether a dedicated consumer helpline is provided; many queries are handled faster via the in-app chat which links the agent to your order and invoice automatically.

Channels and priorities — when to call vs. chat vs. email

• In-app chat (recommended): available through the Klarna app; average response time is typically under 15 minutes for routine queries because the agent sees your account and recent transactions.
• Regional phone support: best for immediate account locks, payment mistakes, or when you require verbal confirmation. Local numbers are published on the regional help pages; expect variable business hours and possible wait times (peak periods 15–45 minutes).
• Email / secure form via help centre: use for disputes requiring documentation (screenshots, contracts). Keep a copy of all correspondence; Klarna assigns a case ID for tracking.

What to prepare before contacting Klarna

Having precise information ready reduces call length and speeds resolution. At a minimum prepare: Klarna invoice number (example format usually 8–12 digits), merchant name, date and amount of the transaction (currency), order number from the merchant, the email/phone registered to your Klarna account, and the last 4 digits of the payment method. If disputing a charge, gather merchant receipts, screenshots of the merchant checkout, and any shipping or return tracking numbers.

Practical tip: take a screenshot of the Klarna transaction line showing the amount and invoice ID. If you are a merchant contacting Klarna Business Support, have your merchant ID and MID available; merchant IDs are typically numeric strings listed in your Klarna onboarding documentation.

Common issues, typical resolution times and escalation

Frequent reasons to contact Klarna: billing disputes (unauthorised charge or incorrect amount), failed payments, payment date changes, returns not reflected in your Klarna balance, and account verification problems. Simple payment-date adjustments or failed payment reschedules are commonly resolved in a single chat session (minutes to hours). Disputes that require merchant confirmation or refund processing can take 7–30 calendar days depending on the merchant and bank processing times.

If you do not receive a satisfactory response within the time frame provided, request a case escalation or a case ID. For unresolved cross-border or regulatory complaints, you can escalate to the local financial ombudsman (for example, the UK Financial Ombudsman Service) or regional data protection authorities for GDPR matters; Klarna’s regional help pages outline complaint escalation paths and timelines.

Practical examples and extra resources

Example: if you are in the United States and see an unexpected “Pay Later” charge, open the Klarna app → select the transaction → “Get help” → choose the issue type → start chat or call. The in-app route attaches invoice ID and merchant info automatically so the agent can research the transaction immediately. If you’re in Sweden and need corporate-level contact, the published switchboard +46 8 120 120 10 and the HQ address Sveavägen 46, 111 34 Stockholm are authoritative for legal or press inquiries.

Final resource checklist: always bookmark https://www.klarna.com and your country-specific customer service page, keep invoice and order IDs to hand, record case IDs, and use the in-app contact whenever possible for the fastest, most accurate support. These practices reduce resolution time from days to hours in most routine cases.
