An IBAN (International Bank Account Number) is an internationally agreed standard for identifying bank accounts across national borders. This calculator helps you extract and verify account details from an IBAN, including bank codes, branch codes, and account numbers.

What is an IBAN?

An IBAN is a unique code that identifies a bank account in a specific country. It's used for international transactions to ensure accurate fund transfers. The IBAN format varies by country but generally includes:

  • Country code (2 letters)
  • Check digits (2 digits)
  • Bank identifier (variable length)
  • Account number (variable length)

For example, a UK IBAN might look like: GB82 WEST 1234 5698 7654 32
