RF reference
Check an RF reference or create one from a base reference using the structured creditor reference format.
Check or create an RF reference
The check and creation are done in your browser. The RF reference is not sent to the server.
This checker covers only technical format and check digits. It does not confirm an invoice, creditor, payment or receivable.
What the RF reference tool shows
The RF reference tool shows whether an RF creditor reference has a valid technical structure, how it is normalized and which check digits belong to it. In create mode, the tool calculates RF check digits for a base reference.
How to use the tool
Choose whether you want to check an existing RF reference or create one from a base reference. Spaces are allowed for readability, lowercase letters are converted to uppercase, and the accepted characters are digits plus letters A-Z.
What is checked or created
In check mode, the tool validates the RF prefix, two check digits, reference part and MOD 97 result. In create mode, you enter the reference part without RF, and the tool adds RF plus the correct check digits.
Check digits and format
An RF reference starts with RF, followed by two check digits and the reference part. The check digits are based on MOD 97, where letters are converted to numbers. This helps catch many typing and copying mistakes.
Examples
- The base reference 12344 can form the RF reference RF0812344.
- The same reference can be grouped for readability as RF08 1234 4.
- If the RF prefix is missing or the check digits do not match, the tool shows an error.
Limitations
The result is technical. It does not prove that an invoice exists, that a payment exists, that a recipient exists, that a debt exists or that a payment will be accepted. Compare the reference with the invoice, payment instructions or recipient before paying.
FAQ
Can I enter an RF reference with spaces?
Yes. Spaces are removed before validation and do not affect the check digits.
Can I use lowercase letters?
Yes. The tool converts letters to uppercase before checking or creating the reference.
Can the RF reference contain non-English letters?
No. In this tool the reference part may contain only digits and letters A-Z.
Does a correct RF reference prove that the invoice exists?
No. A correct RF reference only means that the technical format and check digits match. It is not a confirmation from a bank, invoice issuer or payment recipient.
