Validate a Dutch IBAN →Dutch IBANs (NL) are the shortest in Europe at just 18 characters. They start with 'NL', followed by 2 check digits, a 4-letter bank code (BBAN), and a 10-digit account number. The Netherlands was an early IBAN adopter and all Dutch banks use standardised 4-letter identifiers (e.g., ABNA for ABN AMRO, INGB for ING). BankValidor validates format, checksum, and bank code.

Frequently Asked Questions
What is a Dutch IBAN?
A Dutch IBAN is an 18-character bank identifier starting with 'NL'. It is used for all domestic and SEPA payments in the Netherlands. The 4-letter bank code embedded in the IBAN identifies the bank: ABNA (ABN AMRO), INGB (ING), RABO (Rabobank), TRIO (Triodos), BUNQ (Bunq). The 10-digit account number follows.
Why is the Dutch IBAN the shortest in Europe?
The Netherlands adopted a compact 10-digit account numbering system that, combined with the 4-letter bank code, results in an 18-character IBAN — the shortest in Europe. By comparison, Malta has the longest IBAN at 31 characters. The short Dutch IBAN means fewer digit-entry errors.
What Dutch bank codes are in IBANs?
Common Dutch bank codes in IBANs: ABNA (ABN AMRO), INGB (ING Bank), RABO (Rabobank), SNSB (SNS Bank), TRIO (Triodos Bank), BUNQ (Bunq), KNAB (Knab), RBRB (RegioBank). The 4-letter code at positions 5-8 of the IBAN identifies the bank.
Can I use a Dutch IBAN for international transfers?
Dutch IBANs are accepted for all SEPA transfers within the 38-country European Economic Area. For international wire transfers outside SEPA (e.g., to the US, Japan, or Australia), you also need the SWIFT/BIC code of your Dutch bank. ING's SWIFT is INGBNL2A; ABN AMRO's is ABNANL2A.
