The specific Action Logement code is an alphanumeric identifier assigned to each employee or applicant when a file is opened. Unlike the unique registration number (NUE/NUR) issued by the national registration system (SNE), this code is specific to the Action Logement Services ecosystem. Losing it or not knowing where to find it blocks access to the AL’in platform and delays any application for social housing.
Difference between the specific Action Logement code and the unique registration number
The unique registration number (NUD/NUR) is generated on demande-logement-social.gouv.fr and identifies the social housing application at the national level. The specific Action Logement code, on the other hand, links the employee to their company’s housing policy. Both identifiers coexist in the applicant’s journey but are not interchangeable.
The specific code is provided by Action Logement Services at the time of file validation. It appears in communications sent by the organization, not in those from the SNE. We regularly observe confusion between these two references, leading to fruitless searches in the wrong correspondence.
Locating the specific code from Action Logement therefore requires exclusively targeting emails and letters issued by Action Logement Services, and not those from the national platform or a social landlord.
Action Logement Emails: where to find the code in your inbox
The specific code appears in several types of automated notifications. The confirmation email for file creation is the first document to check. It is sent from an address ending in @actionlogement.fr and contains a summary of the application with the code in the header or body of the message.

To find this email, we recommend a targeted search in the inbox using the following terms:
- “Action Logement” combined with “code” or “file” in the email client’s search bar
- “Application confirmation” or “summary” associated with “ALS” (acronym for Action Logement Services)
- The exact sender address, often of the type [email protected], by filtering by sender
- “Visale” or “certificate” if the application includes the Visale guarantee, as notifications related to this scheme also contain file identifiers
Be sure to check the spam and junk folders. Automated emails from Action Logement frequently end up there, especially on public email services.
Action Logement Paper Mail: locations of the specific code
Action Logement Services also sends physical letters at certain stages of processing. The specific code generally appears in the reference block at the top right of the letter, under the mention “Ref. file” or “Beneficiary code”.
This block contains several pieces of information: the ALS file number, the opening date, and sometimes the name of the contributing company. The specific code is distinct from the ALS file number, although they appear in the same area. The ALS file number is an internal tracking identifier, while the specific code serves to identify the employee in the digital journey.
If you have digitized your letters, a text recognition (OCR) search with the word “code” or “specific” in your document manager speeds up the location.
AL’in Personal Space and Code Regeneration
The specific code remains accessible in the personal space on the Action Logement website, under the “My file” or “My information” section. Accessing the personal space requires the email address used when creating the account and the associated password.
In case of total loss of the code and inability to find it in letters or emails, the Action Logement customer service (0 970 800 800) can provide it after verifying identity. We recommend preparing the usual supporting documents before the call: ID, latest pay slip, and employer’s name.

Recent developments in the digital journey of Action Logement, particularly around the Visale guarantee, have strengthened the integration of identifiers in automated notifications. Emails issuing Visale certificates now contain the contract number and the specific code in the same message, providing an additional recovery point for beneficiaries of this guarantee.
Common mistakes that prevent finding the code
The first mistake is searching for the code in emails from the national registration system (SNE). The SNE manages the NUE/NUR, not the specific Action Logement code. The two communication channels are separate.
The second mistake concerns the email address. If the Action Logement account was created with a professional address and the employee has since changed employers, notifications will be unavailable in their personal inbox. In this case, checking the old professional email remains the only option before contacting customer service.
The third trap: confusing the specific code with the ALS file number displayed on the AL’in platform. The ALS file number allows tracking the progress of a housing application, but it does not replace the specific code during certain administrative procedures or when linking to a contributing company.
Keeping the specific code in a password manager or a dedicated document as soon as it is received avoids these situations. For employees managing both a social housing application and a Visale guarantee simultaneously, noting both identifiers (specific code and Visale contract number) in the same place reduces the risk of confusion between the different references in the Action Logement journey.
