Calculate or check an Italian IBAN

Enter the check letter (CIN), bank code (ABI), branch code (CAB) and account number (numero di conto). The calculator pads short numbers with zeros, works out any national check digits you leave empty and adds the two IBAN check digits.

Switch to Check to paste an IBAN instead: it tests the length, characters, check digits and national check, and shows the bank, branch and account parts. Nothing you type leaves the page.

Frequently asked questions

  • 27 characters: IT, two check digits, then the check letter (CIN), bank code (ABI), branch code (CAB) and account number (numero di conto). Printed in groups of four, it looks like IT60 X054 2811 1010 0000 0123 456.

  • Yes. The letter after IT and the check digits is the CIN, a check character computed from the five-digit ABI, the five-digit CAB and the 12-character account number. Leave the CIN empty and the calculator works it out, then adds the IBAN check digits.

  • Yes. Italy is an EU member state, so it is in SEPA: euro payments to an Italian IBAN can go by SEPA credit transfer.

The check letter (CIN), bank code (ABI), branch code (CAB) and account number (numero di conto) and the country code IT are turned into digits, and the two check digits are chosen so the whole number leaves a remainder of 1 when divided by 97. The calculator does this for you and rejects any input that cannot make a valid IT IBAN.

  • Yes. The calculator and the checker run entirely in your browser: the details you enter are never sent to a server, stored or shared. There is no sign-up and no fee.

  • Yes. The calculator covers 41 countries and the checker all 89 in the SWIFT IBAN registry. Pick a different country in the form above, or open its page from the list below.
