You receive a letter bearing the mention “Inser Asaf” and the address 121 rue Manin, 75019 Paris. Before responding or providing personal information, a few simple checks can help distinguish legitimate mail from a scam attempt. The Inser Asaf association has existed since 1984; it supports homeless individuals and offers administrative domiciliation services. A letter sent from this address can therefore be completely authentic, but this does not exempt you from checking several concrete elements.
SIREN and RNA number: the two identifiers to check first
Every registered association in France has a SIREN number and an RNA number. These are unique identifiers, assigned by the State, that function like an identity card for the organization.
For Inser Asaf, the official SIREN number is 440 060 762. You can verify it in a few seconds on the government business directory (annuaire-entreprises.data.gouv.fr). If the letter you received mentions a different SIREN, or does not mention one at all, this is a first warning sign.
Specifically, open the official directory website, type “Inser Asaf” or directly the SIREN, and compare the displayed information with that of the letter. The address, exact name, and legal status (registered association) must match. A simple step that allows you to verify a letter from the Inser Asaf association at 121 rue Manin Paris by cross-referencing public data.
Inser Asaf letter: mandatory mentions to identify on the document
A legitimate letter issued by a serious association always contains a certain number of identifiable elements. You do not need legal knowledge to spot them.
Here is what you should find on the document:
- The full name of the association as it appears in the official registers, not an isolated acronym or an approximate variant.
- The address of the head office (121 rue Manin, 75019 Paris for Inser Asaf), consistent with that declared in the business directory.
- The SIREN or RNA number, printed legibly.
- The name and position of an identifiable responsible person (president, director, project manager), not just “the mail service”.
The absence of any of these elements does not automatically mean that the letter is fraudulent. However, a letter without any verifiable mention should be treated with the utmost caution.
The trap of different response contact details
A warning sign often overlooked concerns the response channel proposed in the letter. The Inser Asaf association has an official website (inserasaf.fr) and an email address linked to this domain.
If the letter asks you to respond to a Gmail, Outlook, or any other generic provider address, caution is warranted. Similarly, a phone number that does not match the one displayed on the official site should prompt you not to call back without prior verification.
The best practice: never use the contact details listed on a suspicious letter. Instead, visit the official website of the association to find a reliable contact number, and call directly to confirm the sending of the letter.
Association domiciliation and mail received in your name: understanding the context
One of Inser Asaf’s main missions is administrative domiciliation. The association welcomes individuals without stable housing and provides them with an address to receive mail, open social rights, and engage in procedures with the CAF, Pôle emploi, or the prefecture.
If you have never been in contact with this association and receive a letter at your personal address, two scenarios arise. The first: the association contacts you as part of a donation or information campaign. This type of mailing is common among charitable organizations. The second: the letter does not actually come from Inser Asaf, and someone is using the association’s identity to obtain your data.
Cross-referencing information remains the only reliable method to decide. SIREN, address, identity of the signer, response contact details: each matching element reinforces the legitimacy of the letter.
Online verification: free tools accessible to everyone
You do not need any special software or a professional account to verify the information of an association. Several public platforms provide access to declared data.
- Business directory (annuaire-entreprises.data.gouv.fr): the official state register, which includes SIREN, head office address, and legal status.
- Pappers (pappers.fr): a search engine that aggregates public data and allows you to view publications in the Official Journal of associations.
- The official website of the association (inserasaf.fr): it presents the services offered, contact details, and addresses of various sites.
If doubts persist after these verifications, you can contact the town hall of the 19th arrondissement of Paris. The Solidarité 19e network, which brings together social support actors in the sector, knows the local structures and can confirm that Inser Asaf indeed operates at this address.
What to do if the letter seems fraudulent
If the elements do not match (missing SIREN, suspicious response address, request for payment to a personal account), do not respond. You can report the attempt on the platform internet-signalement.gouv.fr, which centralizes reports of online and mail fraud.
A legitimate letter from a registered association never asks for copies of identity documents to be sent by email to a generic address, nor for money to be transferred to a personal bank account. Any request of this type should trigger a systematic verification reflex, regardless of the displayed sender.
