The Creditor Reference (also called the Structured Creditor Reference) is an international business standard based on ISO 11649, implemented at the end of 2008.
The Creditor Reference was first implemented within the SEPA rulebook 3.2.
A vendor adds the Creditor Reference to its invoices. When a customer pays the invoice, the company writes the Creditor Reference instead of the invoice number in the message section, or places a Creditor Reference field in its payment ledger.
When the vendor receives the payment, it can automatically match the remittance information to its Accounts Receivable system.
The Creditor Reference is an alphanumeric string, 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.
The remaining part of the Creditor Reference (up to 21 alphanumeric characters) is the Reference. The content of the Creditor Reference can be determined without any restrictions.
Example: RF18 5390 0754 7034 [In this example, the check digits are "18". The message is structured in print format.]
