Since 2017, French police officers have been required to wear a unique identification number known as the RIO (Répertoire des Identifiants Opérationnels). This measure was introduced to increase transparency and accountability during interventions. However, reports and citizen observations indicate that many officers still do not display the number visibly, often hiding it under equipment or clothing.
According to a 2023 report by the Défenseur des Droits, the lack of visible RIO numbers undermines public trust and makes it difficult to file complaints. The report recommended stricter enforcement and sanctions for non-compliance. As of mid-2026, no major legislative changes have been adopted to address this issue.
Police unions argue that displaying the RIO can expose officers to online harassment or retaliation. They call for better protection mechanisms rather than punitive measures. The Ministry of the Interior has stated it is working on a balance between transparency and officer safety, but concrete steps remain limited.
