The service first checks to see if an account is open and in good standing.

A second validation level searches the customer's record for bounced checks.

Fee-based online verification is available if you need more information, such as when account verification is part of a credit application.

The IBAN validator will also decode and identify the country, bank/branch routing details, and bank account number.An IBAN consists of a two-letter country code FR (which indicates France in this case), followed by a two-digit checksum 14 and a domestic bank account number consisting of up to thirty alphanumeric characters 2004 1010 0505 0001 3M02 606.Domestic bank account numbers, often referred to as a Basic Bank Account Number or BBAN, consist of a branch or routing codes and the account number which in some countries may include alphabetics; all BBANs conform to ISO 13616.For some businesses, simply knowing whether a customer’s checking or savings account is open is not enough.

Although a validation system cannot make decisions for you, most will include recommendations with verification results.
