CIF in the request is invalid
What it means
RO e-Factura answers with this message when the CIF sent as a request parameter, to the upload or message list service, is not a number or is not accepted by the system.
The usual cause
The cif parameter must be numeric. Check the value your software sends for letters or other characters, such as a country prefix.
How to fix it
Check that the CIF is correct, send it as digits only and try again. If an invoicing program sends it, check the company tax identifier the program uses.
