What this check covers
Dutch IBANs are compact at 18 characters and expose a four-letter bank identifier after the checksum.
The checker removes spaces, converts the value to uppercase, moves the first four characters to the end, converts letters to numbers, and confirms that the modulo-97 remainder is one.
Netherlands IBAN structure
The expected layout is NL + 2 check digits + 4-letter bank code + 10-digit account number. This page compares the 18-character fixture with that structure.
A passing checksum does not prove that an account exists, identify its owner, or confirm that a transfer can be completed. An official institution check is still required.
