An IBAN (International Bank Account Number) is a standardised international code that identifies a specific bank account for cross-border transactions. It is used in 89+ countries and is required for all SEPA payments within Europe. An IBAN uniquely identifies both the country, the bank, and the specific account — eliminating the routing errors common before its introduction.
IBAN stands for International Bank Account Number. First standardised under ISO 13616 in 1997, it was designed to simplify cross-border euro transfers — particularly within Europe. Today it is used for all SEPA payments across 41 European countries. Without an IBAN, international transfers to European accounts are significantly slower and more error-prone.

How an IBAN Is Structured
An IBAN consists of up to 34 alphanumeric characters, though the exact length varies by country. Every IBAN begins with a two-letter country code (e.g., NL for Netherlands, DE for Germany), followed by two check digits — a mathematical validation number that verifies the IBAN was entered correctly before processing. After the check digits comes the BBAN (Basic Bank Account Number), which contains the bank identifier code and the domestic account number. The BBAN format and length are set by each country's national banking authority.
Netherlands NL IBAN — Always 18 Characters
Publicly documented example IBAN used for format illustration only.
Netherlands NL IBANs are exactly 18 characters long. Common bank codes: ABNA (ABN AMRO), INGB (ING), RABO (Rabobank), SNSB (SNS Bank). Since 2014, Dutch businesses must use IBANs for all euro transfers. NOWE Money B.V., registered in Amsterdam (KvK 98048260), issues Netherlands NL IBANs to individuals and registered companies worldwide. A NOWE NL IBAN begins with NL and is accepted everywhere within the SEPA zone for free euro transfers.
IBAN vs SWIFT — What’s the Difference?
For SEPA transfers within 41 European countries, you only need the recipient’s IBAN. For transfers outside SEPA — or non-EUR currencies — you need both IBAN and SWIFT/BIC.
How to Find Your IBAN
Online banking
your IBAN is under Account Details or Account Information.

IBANs are listed alongside your account number and sort code.
Ask your bank
phone, branch, or in-app chat. For NOWE accounts, your NL IBAN is shown in the dashboard immediately after verification.
Do You Need an IBAN for International Transfers?
Within Europe, yes — an IBAN is required for all SEPA payments. Outside Europe, it depends on whether the destination country uses IBANs.
IBAN for Business Invoices and B2B Payments
If you invoice European clients, include your IBAN on every invoice. Without an IBAN, EU clients must use SWIFT — which costs them €15–50 per transfer in bank fees. A Netherlands NL IBAN allows EU clients to pay via free SEPA.
Read moreWhat Countries Use IBAN?
By December 2024, 89 countries had adopted IBAN — all 27 EU member states, UK, Norway, Switzerland, and many countries in the Middle East and North Africa. The US, Canada, Australia, New Zealand, and China do not use IBAN for domestic transfers.

IBAN Identifies Your Account
IBAN vs SWIFT — IBAN identifies a specific bank account. SWIFT/BIC identifies a bank or branch. Both are needed for international SWIFT transfers; for SEPA, IBAN alone is sufficient since 2016.
