The French mandatory staff register: an overlooked duty from your first hire

Did you just hire your first employee — a trainer, a pedagogical assistant, a part-time accessibility referent? Without necessarily knowing it, you now carry a legal obligation that has nothing to do with Qualiopi but can prove costly in an inspection: keeping a registre unique du personnel (mandatory staff register). Here is what it must contain, who belongs on it, and what you risk without one.

Who is concerned, and from when

The obligation begins from the hiring of your first employee, with no staff-size threshold (articles L. 1221-13 to L. 1221-15-1 of the French Labour Code). A training organisation incorporated as a company that hires a trainer on a permanent or fixed-term contract, even part-time, must open its register from day one.

Conversely, you are not concerned if:

• you are a sole trader (auto-entrepreneur) or solo director with no employees at all (see our article on the auto-entrepreneur training organisation);
• you only work with subcontracted trainers or trainers under umbrella-company arrangements: it is their respective employers (their own structure, or the umbrella company) who keep the register, not you. Our guide on obligations toward subcontracted trainers details this distinction, which matters for indicator 27 of the Référentiel National Qualité.

Who must be listed on the register

The register covers all of the organisation’s employees, whatever their contract type, plus certain non-employed people present on the premises for another reason:

• employees on permanent (CDI) and fixed-term (CDD) contracts, including part-time;
• temporary agency workers and staff made available by an employer group (groupement d’employeurs);
• interns hosted as an employer under a work-placement agreement (typically a business or administration student on placement supporting admin or marketing tasks) — entered in a dedicated section of the register, separate from employees.

A point specific to training organisations: do not confuse these interns with your training participants — the learners enrolled in your courses. The latter have no place whatsoever in the registre unique du personnel; they fall under an entirely different legal framework (training agreement or contract, attendance sheets, certificates of completion).

Mandatory entries

Article D. 1221-23 of the Labour Code sets the minimum content. For each person, the register must show:

Entry	Detail
Surname and first names	Recorded in hiring order, in an indelible manner
Nationality	—
Date of birth	—
Sex	—
Job held	Job title
Qualification	Level, diploma or certification where applicable
Start and end dates	At the establishment
Contract-type mention	“CDD”, “salarié temporaire” with the agency’s name and address, or “mis à disposition par un groupement d’employeurs” as applicable
Work-permit reference	For any foreign employee subject to this requirement, the type and reference number of the permit

No specific format is imposed: a bound paper register or a digital file both work, as long as entries are time-stamped and cannot be altered after the fact. Switching to a digital format requires the prior opinion of the works council (CSE) where one exists.

Retention, location and access

Entries must be kept for 5 years from the date the employee or intern leaves. The register must be kept on the premises, permanently available to:

• the labour inspectorate, which can consult it at any time during an inspection;
• CSE members, where a works council exists;
• social-security control agents (URSSAF in particular) as part of an undeclared-work (travail dissimulé) check.

Why this document matters beyond mere formality

The registre unique du personnel is not an administrative relic without stakes: it is one of the reference tools used by the labour inspectorate and URSSAF to check that an employer is not concealing employment. A study published in Économie et Statistique by Insee (Aït Bihi Ouali & Bargain, 2021) shows, based on a pilot fraud survey, that undeclared work remains significant in France and is explained less by the employer’s socio-demographic profile than by behavioural and perceptual factors — notably the belief that documentary checks will remain superficial. An up-to-date register, consistent with employment contracts and social declarations, is precisely what makes this kind of check quick and unambiguous for your organisation.

For a training organisation, this document has a second, less obvious benefit: consistency with your trainer competence file. If you present a trainer as an employee under indicator 21 on the competences of trainers, an attentive auditor or DREETS inspector may cross-check that claim against the entry dates in the register. A mismatch — a “salaried” trainer with no trace in the register, or a hire date after the first sessions they delivered — undermines your file well beyond the register question alone. Our article on the trainer competence file details the evidence expected for each trainer.

Penalties for absence or irregularities

Failure to keep a register, failure to present it during an inspection, or incorrect or incomplete entries expose the employer to a fourth-class contravention fine (contravention de 4e classe), applied per employee concerned:

• up to €750 for an individual employer;
• up to €3,750 for a legal entity (the individual amount is multiplied by five, under article 131-41 of the Criminal Code);
• this amount can be doubled in case of repeat offence within the year.

Because the fine is calculated per employee concerned, a missing or outdated register in an organisation employing several trainers and an administrative team can quickly add up to a significant sum — not to mention the negative signal it sends the labour inspectorate, which rarely gives the benefit of the doubt on the rest of your social-compliance file after that.

Setting up your register: the checklist

• Register opened from the hiring of the first employee, paper or digital (CSE opinion sought if digital and a CSE exists)
• One line per employee, in chronological hiring order, never rewritten afterwards
• All nine entries from article D. 1221-23 completed for each person
• A separate section for any school/university interns hosted, distinct from employees
• Retention for 5 years after departure, including for people who have left the organisation
• Register kept on the premises, never only at the accountant’s office

Take action

The registre unique du personnel adds to a list of administrative obligations that every training-organisation founder must master alongside their Qualiopi journey. The Kit Certif Complet (€297, 14-day guarantee) provides the documents and evidence expected during an audit, including competence files for your salaried trainers. If you are just starting out and making your first hire, the ebook “Créer son organisme de formation en 30 jours” (€67) walks through a new employer’s obligations step by step, and the full Pack (€347) bundles both resources.
