The attribution of the Siret number by Pajemploi does not always follow an immediate logic. Some individual employers notice an unexpected delay or a lack of automatic sending, despite the initial declaration of a home employee. Access to this number is essential for validating most administrative procedures related to home employment.
This unique number is not always obtained from the expected organizations, and its display sometimes depends on the Pajemploi personal space, which is rarely mentioned during the first exchanges. The steps to follow and the solutions in case of forgetting remain unknown, even though they condition the regularity of the procedures.

Why the Pajemploi Siret number is essential for your individual employer procedures
The Pajemploi Siret number is the key without which the administrative journey of the individual employer gets stuck. Assigned by Insee at the request of Pajemploi, this code is not just a marker: it officially certifies your status as an employer with the social organizations. Without this number, it is difficult to carry out a pre-employment declaration, issue a payslip, pay your social contributions, or even request the free choice of childcare supplement.
As soon as you communicate with social security, Caf, or MSA, this unique number will be requested. Its absence blocks everything: management of social rights, validation of worked periods for your childcare assistant or nanny, proof of declared employment. Therefore, this number is not limited to Pajemploi: it permeates the entire administrative circuit related to the employment of a nanny or a home employee.

Frequently asked questions: everything you need to know about using and managing your Siret number
What is the Siret number actually used for?
The Siret number formally distinguishes each individual employer with social organizations. This unique code appears on all major documents: pre-employment declaration, payslip, Pajemploi certificates. For each declaration, whether you are hiring a licensed nanny or a childcare assistant to care for your child, it becomes essential. Without it, no social contributions are paid, and no rights are opened for your employee.
Should the Siret number be included on the employment contract?
Including the Siret number on the employment contract is strongly advised. This mention proves your legal status as an employer and simplifies all subsequent procedures, especially when transmitting the file to Caf or MSA for the free choice of childcare supplement (CMG). Write it at the top of the contract or in the section dedicated to administrative matters.
What steps to take in case of a change in situation?
Here are the reflexes to adopt if your situation changes:
- Moving? Update your address in your Pajemploi space. The Siret number remains the same unless there is a change in employer status.
- Are you changing the number of children being cared for? Declare it on the Pajemploi portal to adjust your rights and the calculation of social contributions.
- Employing multiple employees? The same Pajemploi Siret number applies to each declaration; there is no need to request a new one.
What to do if the Siret number does not appear on your documents?
If the number is missing, contact Pajemploi by phone or through your online space. All employer certificates issued by Pajemploi mention this number, which is essential for tracking your procedures and ensuring your employee’s social rights. Taking this precaution avoids many complications and secures your journey as an employer.
Ultimately, the Pajemploi Siret number is not just a formality: it is the piece that locks each step of your life as a home employer. Ignoring it risks moving forward without a safety net on the administrative tightrope. It is best to locate it, keep it safe, and proceed with peace of mind.
