IBAN country format
Netherlands IBAN Format, Length and Dutch Example
Use this guide to understand the IBAN country code for Netherlands, its 18-character length, and example formatting. The NL value shown below remains clearly marked as an example/test IBAN rather than a confirmed bank account.
A Dutch IBAN contains 18 characters and displays a four-letter bank identifier before the ten-digit account number.

The four-letter Dutch bank code inside an NL IBAN
The Swift IBAN Registry pattern for this published format is NL2!n4!a10!n.
The Netherlands table maps each published segment to the
NL91ABNA0417164300 example/test value.
| Part | Positions | Swift pattern | Example segment |
|---|---|---|---|
| Country code | 1-2 | 2 letters | NL |
| International check digits | 3-4 | 2 digits | 91 |
| Bank identifier | 5-8 | 4 letters | ABNA |
| Account number | 9-18 | 10 digits | 0417164300 |
This NL breakdown describes visible positions; it does not turn the embedded bank or routing fields into a live Netherlands institution lookup.
ABNA as part of the IBAN, not a separate BIC
The NL diagram shows the four-letter bank identifier between the IBAN check digits and the ten-digit account number.
- 1. Country code 1-2; 2 letters
- 2. International check digits 3-4; 2 digits
- 3. Bank identifier 5-8; 4 letters
- 4. Account number 9-18; 10 digits
Synthetic example, not a real account. The blocks show character positions only and do not identify a live bank or account.
Reading the short NL91 example
The synthetic/test NL value demonstrates the published Netherlands layout. Preserve its label and never treat the sample as a recipient's real payment instruction.

Letters in the Dutch BBAN are expected
- 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.
Bank-code visibility in the Netherlands layout
The Netherlands uses an 18-character IBAN, one of the shorter formats in this published set. After NL and the two international check digits, the Swift IBAN Registry describes a 14-character BBAN containing a four-letter bank identifier followed by a ten-digit account number. The letters are part of the Dutch IBAN itself. They are not a separate BIC and must remain when spaces are removed for digital entry. A digits-only Dutch value is therefore not consistent with this national format.
Because a Dutch IBAN is short, copying extra text can be as important as spotting a missing character. Invoice systems may place a payment reference, company registration number, or BIC close to the IBAN. Paste only the 18-character value into the checker, preserve any leading zero in the account portion, and compare the four bank letters with the original document. MOD97-10 can catch many substitutions and transpositions, but it cannot tell whether the source document itself contained the correct beneficiary details.
The four-letter bank identifier gives structural context, not live institution status. BankCodeKit does not query a Netherlands bank directory, account service, or payment network, and it does not infer a BIC from the IBAN. Review any BIC separately and confirm the payee name, amount, currency, and reference through the bank or recipient. If a supplier announces a new account, treat that change as a verification event rather than relying on a green format result. Format consistency does not establish account existence, control, or transfer success.
What the NL length and checksum review covers
- Whether the IBAN starts with the NL country code.
- Whether the IBAN has 18 characters after normalization.
- Whether the value uses allowed letters and digits.
- Whether the MOD97-10 checksum is valid.
Removing spaces while keeping ABNA intact
For Netherlands, compare the grouped invoice-style value with the compact NL input produced after presentation spaces are removed.
- Input shown on page
- NL91 ABNA 0417 1643 00
- Normalized digital value
- NL91ABNA0417164300
- Expected length
- 18 characters
- Result interpretation
- A passing NL result means the visible value matched supported Netherlands structure and MOD97 rules, not that the account or payee was verified.
Compare the Dutch IBAN with separate bank codes
- Check this NL IBAN locally for country, length, characters, and MOD97 result only.
- Review Netherlands's SEPA country entry as reference context, not bank or account readiness.
- Compare the IBAN with a separate BIC/SWIFT code when a Netherlands invoice supplies both values.
Do not strip the Dutch four-letter field
- Assuming the four-letter bank code is a separate BIC and removing it from the IBAN.
- Confusing the short 18-character NL IBAN length with longer neighboring-country formats.
When the compact NL format helps spot errors
- Checking Dutch payment details where the IBAN includes a visible bank-code segment.
- Reviewing whether the input should be checked as an NL IBAN before comparing any BIC/SWIFT code separately.
- Use the IBAN Checker after this Netherlands reference when you need a local MOD97 result for one NL value.
