What Is an IBAN Number and What Is It Used For?

IBAN is an international standard for identifying bank accounts, regulated by ISO 13616. It was introduced to standardize the handling of cross-border transfers and reduce errors in payment processing. The IBAN number makes it possible to unambiguously identify the country where the account is held, the bank, and the customer's specific account.

IBAN is used primarily for international transfers, including SEPA transfers carried out in euros within the European Union and the European Economic Area. It is also increasingly used in domestic transactions, especially in companies' accounting and settlement systems. Thanks to standardization, banks can automatically verify whether a number is correct before processing a transfer.

When Are the IBAN Number and ING Bank Śląski's SWIFT Code Required?

The IBAN number is required when funds are sent from abroad to an account held at ING Bank Śląski, as well as for transfers from Poland to foreign recipients. This applies to private and business settlements, including payments resulting from invoices issued to contractors from outside the country. The absence of an IBAN number may result in the order being rejected or its processing time being extended.

For some international transfers, particularly those carried out outside the SEPA area, it is also necessary to provide the bank's BIC/SWIFT code. The SWIFT code of ING Bank Śląski is INGBPLPW and is used to identify the bank in the international SWIFT settlement system. For SEPA transfers, the IBAN number alone is usually sufficient; however, some banks still require both identifiers to ensure that the funds are credited correctly.

Can the IBAN Number Be Shared with Other People?

The IBAN number can be shared with other people without concern for the security of the funds, as it serves solely to identify a bank account. This is necessary when a transfer is made from abroad or when a payment is made by a contractor from outside Poland. Providing an IBAN number is standard practice in international settlements, on invoices, in contracts, and for one-time private transactions, and it does not provide access to the account.

At the same time, the IBAN number identifies the bank and account number, so it should be shared only with people and institutions that are actually going to make the payment. It is safe to provide it to an employer, contractors, or public offices, but publishing the IBAN number in publicly accessible places is not recommended.
