List of error messages for failed identification

Here you will find the errors that a Signer may encounter during the identification phase of a Qualified Electronic Signature (QES).

The identification step is crucial in a Qualified Electronic Signature (QES) to ensure that the person signing is who they claim to be. For this purpose, we have a facial identification step and information matching with the ID document used.

In a case of a failed identification, the Signer will be redirected to a page indicating the reason(s) of the failure to guide the User to a new, optimized attempt.

Here is an example of the page with one of the possible errors:


Document & Video quality issues

For a successful identification, we need an original document, not a copy, of good quality, with a good quality connection maintained throughout the process. The Signer must also be careful not to have a blurred camera, and not to have anything obscuring his face (hat, glasses, long hair).

Identity matching issues

For a successful identification during the QES, we need a strict match between the information extracted on the ID document used by the Signer and the first name and last name entered by the Sender, to ensure the quality of the signature certificate issued and to avoid potential legal disputes.

Here's a list of errors linked to incorrect identity information matching:

Error nameError messageAdvice provided
FIRSTNAME MISSING (2)It appears that your first name is missing from your ID. It is impossible for us to identify you with the ID document used.Try again with another identity document that contains a first name distinct from the last name.
FIRSTNAME MISMATCHIt appears the first name provided by the sender and the first name on your identity document don’t match.Check that the first name declared by the Sender is strictly one of your given names on your identity document.
LASTNAME MISMATCHIt appears the last name provided by the sender and the last name on your identity document don't matchCheck that the last name declared by the Sender is strictly one of your last names (married, birth or usage) on your identity document.
PROBABLY TOO MANY LASTNAME PARTSIt appears the sender declared too much last names and we couldn't match them on what is displayed on your identity document.Check that the last name declared by the Sender is strictly one of your last names (married, birth or usage) on your identity document.

FIRSTNAME LASTNAME INVERSIONIt appears your last name and first name were reversed in the information declared by the sender.Check your information and declare an error so that the Sender can correct the inversion.

(2) - For the FIRSTNAME MISSING error, this is mainly due to ID documents that do not contain the first name, or else the first name has been integrated with the surname and the first name field has been left empty. We highly recommend that you advise your users to use another identity document: we do not support ID document.
