Check a Dutch IBAN and identify its bank
A Dutch IBAN has 18 characters. Positions 1–2 contain NL, positions 3–4 the IBAN check digits, positions 5–8 a four-letter bank code and positions 9–18 the ten-digit account number. For NL91 ABNA 0417 1643 00, the bank code is ABNA and the account number is 0417164300.
The checker validates the fixed format and Modulo 97 checksum, then matches the bank code with the official BIC list from the Dutch Payments Association. It can show the bank, BIC, bank code and account number, but it cannot verify the account holder's name or account status.
What information can an IBAN checker provide?
An IBAN contains a country code, checksum and country-specific account details. The iban24 checker validates this structure for all twelve supported countries and retrieves the encoded bank identifier, optional branch code and account number. When bank data is available, it also displays the bank name and BIC.
This helps when checking payment details from an invoice, separating an IBAN into fields required by accounting software, or finding the BIC for an international form.
How to check an IBAN
- Enter the IBAN with or without spaces.
- Select Check IBAN.
- Review the checksum result and retrieved bank information.
- Copy individual fields if required.
The checker removes formatting spaces, confirms that the length and character pattern match the country, and validates the Modulo 97 checksum. It then looks up the bank code in the available regional dataset.
What a valid result means
A valid result means that the IBAN is structurally plausible and its checksum is correct. It does not confirm that the account is active, that funds can be received, or that the named payment recipient owns the account. Account-holder information is not encoded in an IBAN.
For new recipients or unusually large payments, confirm bank details through a separate trusted channel. A checksum protects against many typing errors, but it does not protect against fraud involving a different valid IBAN.
Supported countries and data sources
Reliable bank matching is available for all twelve supported countries. The page shows the applicable official source and the most recent successful update date when known. Bank names and BICs come from those datasets and may lag behind very recent institutional changes.
