Understanding IBAN Structure and Format
An IBAN (International Bank Account Number) is a standardized international numbering system developed by the International Organization for Standardization (ISO) and the European Committee for Banking Standards (ECBS). It's designed to facilitate automatic processing of money transfers and reduce errors in cross-border payments.
IBAN Components
- Country Code: 2-letter ISO country code (e.g., GB, DE, FR)
- Check Digits: 2 digits calculated using MOD-97 algorithm
- Bank Identifier: Bank code specific to each country
- Branch Code: Branch identifier (where applicable)
- Account Number: Customer account number
IBAN Length by Region
IBAN Validation and MOD-97 Algorithm Explained
Our iban validator uses the official MOD-97 algorithm specified in ISO 13616 to verify IBAN authenticity. This mathematical check ensures that the IBAN structure is correct and helps prevent typing errors that could result in failed payments or funds being sent to wrong accounts.
Validation Process
- Move the first 4 characters to the end of the IBAN
- Replace letters with numbers (A=10, B=11, ..., Z=35)
- Calculate the remainder when divided by 97
- Valid IBANs have a remainder of 1
Common Validation Errors
- Incorrect IBAN length for the country
- Invalid country code
- Wrong check digits
- Invalid characters in bank or account fields
- Incorrect BBAN structure
