How an IBAN from Netherlands is built
The registry’s example, NL91 ABNA 0417 1643 00, split into its parts:
- CountryNL
- Check digits91
- Bank codeABNA
- Account number (rekeningnummer)0417164300
| Part | Positions | Format | In the example |
|---|---|---|---|
| Country | 1–2 | 2 letters | NL |
| Check digits | 3–4 | 2 digits | 91 |
| Bank code | 5–8 | 4 letters | ABNA |
| Account number (rekeningnummer) | 9–18 | 10 digits | 0417164300 |
What the parts are called in Netherlands
A Dutch IBAN has 18 characters: NL, two check digits, a 4-letter bank code (such as ABNA, INGB, RABO) and a 10-digit rekeningnummer.
The bank code is the start of the bank’s BIC. Most Dutch account numbers pass the “11-test”; former Postbank numbers (now ING) do not, so we show a failed 11-test as a hint only.
The check digits of NL91 ABNA 0417 1643 00
- Move the first four characters to the end: ABNA0417164300NL91
- Replace each letter by a number (A = 10, B = 11 … Z = 35): 101123100417164300232191
- Divide that number by 97. The remainder is 1; a valid IBAN always leaves 1.
- To calculate the check digits instead, put 00 in their place: the remainder is 7, and 98 − 7 = 91.
The national check inside the account number
Most Dutch account numbers pass the 11-test: the digits multiplied by 10, 9, 8 … 1 add up to a multiple of 11. Old Postbank numbers (now ING) do not, so a failed test is only a hint.
