Some organisations need to collect a supplementary supporting document to confirm a person’s identity. Collecting a second identity document is recommended in cases of doubt concerning a person’s identity in article 39 of the fourth directive from the ACPR (the French prudential supervision and resolution authority). The additional document must contain information that confirms the customer’s identity, i.e. full name and date and/or place of birth for natural persons. One possibility is thus a health insurance card, as long as the part of the social security number not needed for identity verification (the last five digits) are masked when taking a copy of the card.
Requesting and verifying this document can be very useful, especially for young people who do not yet have a passport or driving licence.
