IBAN Checker: Validate & Scan

Check an IBAN before the money moves. IBAN Checker validates any International Bank Account Number in an instant — checksum, length and country format — so a mistyped digit never sends a transfer astray.

KEY FEATURES

• Instant validation — paste or type an IBAN and see immediately whether the checksum and country format are valid
• Camera OCR scan — point your camera at an invoice or bank letter and the IBAN is read straight off the paper
• QR code scanning — read IBANs from payment QR codes in one tap
• Bulk validation — check a whole list of IBANs at once, then copy the results or save the valid ones
• IBAN calculator — build a valid IBAN from national account and bank codes
• Country guide — formats, lengths and examples for every IBAN country
• Payment instructions — turn a checked IBAN, BIC, amount and reference into a ready-to-share payment note
• Validation history — valid IBANs kept locally, with CSV export

BUILT FOR ACCURACY

Validation uses the official checksum algorithm plus the per-country length and structure rules of the SWIFT IBAN registry, and tells you what is wrong when a number fails: length, format or check digits. Formatting groups the digits the way banks print them, so comparing against paper is easy.

PRIVATE BY DESIGN

• Everything is checked on your device — IBANs are never sent to a server
• No account and no sign-up
• Optional biometric lock keeps your history behind your fingerprint
• A home screen widget showing your latest check

WHY CHOOSE IBAN CHECKER

• Type, scan or photograph — three ways to get an IBAN in without retyping errors
• Bulk mode saves accounting teams real time
• The country guide answers "is this even the right length for Germany?"
• Clean Material design with dark mode

PERFECT FOR

• Anyone sending an international transfer who wants to check the IBAN first
• Freelancers and small businesses checking customer bank details on invoices
• Accountants validating supplier lists in bulk
• Frequent travelers dealing with accounts across countries

IBAN Checker verifies number structure only — it cannot confirm that an account exists or belongs to a particular person. Always confirm recipient details through your bank.

Check your next IBAN before you send — it takes two seconds.
