The code of the affiliation organization: what you need to know

Partager

The affiliation organization code is a key element for companies in France, especially regarding the management of their employees’ social security. This code allows identifying the organization responsible for managing social contributions and social benefits of the company. In this article, we will explain what the affiliation organization code is, how to obtain it, and why it is important for businesses to know it. We will also address the legal obligations associated with this code and the consequences of errors or its absence.

What is the affiliation organization code?

The affiliation organization code is a unique identifier used to designate the organization responsible for social security management of a company. This code is assigned by the Central Agency of Social Security Organizations (ACOSS) for recovery organizations (such as URSSAF, RSI, or MSA) and by the Primary Health Insurance Fund (CPAM) for health insurance organizations.

This code consists of four digits corresponding to the identifier of the affiliation organization, followed by three digits representing the identifier of the affiliated agency. For example, the URSSAF code for Paris is 751 for the organization identifier and 001 for the agency identifier, making the full code 751001.

Businesses need to know their affiliation organization code because it allows determining the applicable social contribution rates for the company and its employees, as well as the social benefits they are entitled to. This code is also used for exchanges with social security organizations, such as the nominative social declaration (DSN) or the reimbursement request for health expenses. The organizations involved with this code include URSSAF, CPAM, the National Old-Age Insurance Fund (CNAV) for pensions, and the National Health Insurance Fund for Salaried Workers (CNAMTS) for health insurance.

How to obtain your affiliation organization code?

There are several ways to obtain your affiliation organization code.

The first method is to search for the code on the organization’s official website. Generally, it is enough to visit the website of the concerned organization and search for the company’s code using its SIRET number or name. It is also possible to contact the organization by phone to obtain this code.

The second method involves requesting the code by mail or phone. To do so, you must contact the organization by phone or mail, providing the necessary information for identifying the company (SIRET number, name, address, etc.). The organization will then send the code by mail or email.

The documents required to obtain the affiliation organization code vary depending on the organization involved. Generally, it is necessary to provide the company’s SIRET number, along with information about its activity (sector of activity, number of employees, etc.). Other documents may be requested, such as extracts from Kbis or proof of identity.

Why is the affiliation organization code important for companies?

The affiliation organization code is an important element for companies because of the legal obligations associated with it.

Indeed, companies are required to declare their affiliation organization code to all social organizations they are affiliated with, such as URSSAF, CPAM, CNAV, and CNAMTS. This declaration must be made when establishing the company and updated regularly if changes occur.

In case of missing or incorrect code, the company can face financial penalties. For example, URSSAF may carry out audits or impose penalties if the company has not correctly declared its affiliation code. Similarly, a missing or incorrect code can cause delays or refusals of health expense reimbursements by CPAM.

The affiliation organization code is also crucial for the relationship between companies and social security organizations. It is used in the social nominative declaration (DSN), which centralizes all employee-related information within a company. The code is also used for exchanges with social security organizations, such as reimbursement requests for health expenses.

Finally, the affiliation organization code is important for employees, as it helps determine the social contribution rates applied to their salaries and the social benefits they are entitled to, such as health insurance or retirement.

In summary

In conclusion, the affiliation organization code is a critical element for companies in France. It enables proper declaration of social contributions and benefits information and facilitates exchanges with social security organizations.

In this article, we explained what the affiliation organization code is, how to obtain it, the associated legal obligations, and the consequences of errors or its absence.
