How IBAN Validation Works
IBAN (International Bank Account Number) is an internationally agreed system for identifying bank accounts. Our validator uses the ISO 13616 standard and mod-97 algorithm to verify IBANs.
IBAN Structure:
- Country Code: 2 letters (e.g., GB for United Kingdom)
- Check Digits: 2 digits for validation
- Bank Identifier: Up to 30 alphanumeric characters
- Account Number: Varies by country
Validation Steps:
- Check country code is valid and supported
- Verify length matches the country's standard
- Apply mod-97 algorithm to check digits
- Extract bank code and account number
Common Questions About IBANs
Which countries actually use IBANs?
70+ countries across Europe, Middle East, and North Africa. Think all of Europe (including UK and Switzerland), plus places like Egypt, Saudi Arabia, and Turkey. But here's the catch: The US, Canada, Australia, and New Zealand don't use IBANs at all. They have their own systems—routing numbers for the US, BSB codes for Australia, etc. So if your American cousin asks for your IBAN to send birthday money, they're probably confused about how international transfers work.
Does this actually check if my account exists?
Nope. Big difference here: This validator checks if the format is correct—like spell-check for bank accounts. It'll catch typos, wrong lengths, invalid country codes. But it can't tell you if the account is active, belongs to who you think it does, or even exists at all. Only the actual bank knows that. What it WILL do: Stop you from sending €10,000 to "GB99 XXXX 1234 5678 90" because that's obviously fake.
Is it safe to paste my real IBAN here?
Yes, it's safe. Everything happens in your browser—we never send your IBAN to our servers or store it anywhere. You could pull your WiFi cable right now and it'd still work. That said, internet safety 101: Don't post your IBAN on Twitter or random websites. While it's not as dangerous as sharing your credit card, scammers can still use it for phishing attempts or create fake invoices.
My bank changed my IBAN. Do I need to update everything?
Probably, yeah. When banks merge, rebrand, or update their systems, they sometimes issue new IBANs. Check your latest bank statement or log into online banking—it'll be there. Then update it with: anyone who pays you regularly (employers, pension), companies that charge you (utilities, subscriptions), and government agencies (tax office). The old IBAN might forward for a while, but don't count on it forever. Better to update now than have your rent payment bounce.
