Netherlands IBAN Format, Length and Dutch Example

How to read this Netherlands IBAN

• The value starts with NL, the IBAN country code for Netherlands.
• The next two characters are international check digits.
• The remaining 14 characters are the country-specific BBAN section: 14 BBAN characters after the country code and check digits.
• Dutch IBANs commonly show a four-letter bank code in the BBAN section after the country code and check digits.
• The example keeps the ABNA letters in the digital format; removing letters changes the IBAN.

• Use the detailed disclaimer for the full list of non-verified items.

Netherlands SEPA context

The local SEPA country reference data lists this country as: SEPA country - EU. Country-level SEPA status does not confirm that a specific bank or account can receive a payment.

Limitation note

This page explains IBAN format rules only. It is not a bank, account, sanctions, fraud-risk, or payment-network check.

Before using this IBAN format for payment

A structurally valid IBAN can still be wrong for a real transfer. Always verify payment details with the invoice issuer, recipient, bank, or payment provider before sending money.
