Rekeningnummers

Rekeningnummers are the unique identifiers assigned to bank accounts by financial institutions. In the Netherlands and other Dutch-speaking regions, these numbers are typically presented today as an IBAN (International Bank Account Number), which standardizes both domestic and international transfers. The term rekeningnummer is commonly used to refer to the account number component, although the IBAN is the standardized format used in most transactions.

An example of a Dutch IBAN is NL91 ABNA 0417 1643 00. The IBAN begins with the country code NL and two check digits, followed by a four-letter bank code and a 10-digit BBAN (the national account number). This structure uniquely identifies the bank and the specific customer account within the bank.

Rekeningnummers are used to send and receive money. For domestic payments, you provide the recipient’s IBAN; for international transfers, the IBAN is used together with the recipient bank’s SWIFT/BIC code. Many banks and businesses require the IBAN to ensure accurate crediting and to reduce errors in transfers.

Where to find and how to handle them: rekeningnummers appear on bank statements, online banking portals, and payment forms. When sharing an IBAN, verify the recipient’s details and share through secure channels. It is prudent to avoid posting full numbers publicly to prevent misuse.
