How Ria's IBAN calculator works

  1. Choose the country where the bank account is held.

  2. Enter the local bank code, branch code (if your country uses one), and account number.

  3. Click Calculate. We'll add the correct country code and run the ISO 13616 check-digit formula.

  4. Copy your IBAN with one tap, confirm it with your recipient, and send.

Heads up: a correctly formatted IBAN means the math checks out, but it doesn't prove the account exists. Always confirm with your recipient or their bank before sending.

Where to find your IBAN

Not sure if you even need to calculate? If you already have an account in an IBAN country, your IBAN is usually easy to find:

  • At the top of a recent bank statement (paper or PDF).

  • In your online banking dashboard, usually under Account details or Receive money internationally.

  • In your bank's mobile app. Most show the IBAN with a one-tap copy button.

  • On the chip side of some debit cards, though this is less common.

Only have your bank code and account number? That's what the calculator above is for.

Frequently asked questions

How do I generate an IBAN?

In countries that use the IBAN system, your bank generates one when you open your account. If you only have your local account number, paste it into Ria's IBAN calculator above. We'll add the country code and check digits to produce a valid IBAN.

Is Ria's IBAN calculator free?

Yes. There's no charge to use the IBAN calculator, and you don't need to sign up or share any personal details. Calculations happen in your browser.

Can I send money internationally with just an IBAN?

Usually you'll also need the recipient's full name and the SWIFT/BIC code of their bank. Some banks ask for additional details for compliance checks. When you start a transfer with Ria, we ask for everything required for your specific destination.

Is it safe to use an online IBAN calculator?

Ria's calculator runs entirely in your browser. We never store, log, or transmit the account details you enter. For added safety, always confirm the IBAN with your recipient or their bank before sending money.
