RF Calculator

The Creditor Reference (also called the Structured Creditor Reference) is an international business standard based on ISO 11649, implemented at the end of 2008. Using Creditor Reference, a company can automatically match its remittance information to its A/R. The Creditor Reference is an alphanumeric string, up to 25 characters long, with the letters "RF" at the beginning. After the letters are two check digits, which confirm that the reference will be entered correctly.
