What is an IBAN and why verify it
The IBAN (International Bank Account Number) is an internationally standardized code that uniquely identifies a bank account. It is used to carry out SEPA transfers and international payments.
Our IBAN check tool is particularly useful before sending a transfer in CHF or EUR, when you receive an IBAN from clients, employers, or suppliers, while entering data into management systems, forms, or payment platforms, and before setting up recurring payments or saving a new beneficiary.

IBAN CHECK
The IBAN check is based on official algorithms defined by the ISO 13616 standard. During the verification process, several technical checks are performed:
- verification of the correct length based on the country
- check of the alphanumeric structure
- checksum validation
- identification of the bank and branch (advanced verification only)

ABI and CAB verification
The Italian IBAN check also allows the identification of ABI (bank) and CAB (branch) codes.
The Italian IBAN consists of 27 characters and includes useful information to identify the relevant banking institution. This type of verification is particularly useful to avoid errors in domestic bank transfers.
Foreign IBAN check
and international
The IBAN check also works for foreign IBANs.
Each country uses a different structure, with variable lengths and specific formats.
The verification allows you to check IBANs from the SEPA area as well as from many non-SEPA countries, identifying the country of origin and the associated bank.
