Administrative domiciliation allows individuals without a stable address to receive mail through an approved organization. When a letter arrives with the mention “Inser Asaf” or the address “121 rue Manin, 75019 Paris,” the question of its reliability arises legitimately. Understanding what this association is, how its accreditation works, and what elements to check on the received mail helps distinguish a legitimate sending from a fraudulent attempt.
Domiciliation Accreditation: The Legal Foundation to Know
In France, only a structure with a prefectural accreditation for domiciliation can officially serve as an administrative address for individuals without a stable home. This accreditation, issued by the prefecture or the competent authority, imposes specific obligations: maintaining a register of domiciled individuals, preserving mail, and providing social support.

Inser Asaf, an association active since 1984 in the 19th arrondissement of Paris, is among the organizations recognized by the City of Paris for domiciliation. Reports from the Réseau Solidarité 19e mention it as an institutional actor in the system. This status goes beyond mere registration in the national register of associations (RNA) or holding a SIREN number.
The procedure for verifying Inser Asaf mail 75019 Paris thus begins with this point: is the association properly accredited for domiciliation in the relevant department? A search on the Paris prefecture’s website or with the SIAO (Integrated Service for Reception and Orientation) can confirm this.

Address 121 rue Manin and Sender: Two Distinct Verifications
A common trap is to confuse the postal address with the identity of the sender. The 121 rue Manin, 75019 Paris, serves as a domiciliation address for individuals supported by Inser Asaf. Therefore, mail bearing this address can come from three different sources.
- The association Inser Asaf itself, in the context of administrative mail related to domiciliation follow-up or social support.
- An individual domiciled at this address, who uses 121 rue Manin as their official address for their own procedures (employment, health, housing).
- A third party who impersonates the address or the name of the association to give a legitimate appearance to a fraudulent sending.
The address alone does not guarantee the identity of the sender. The name “Inser Asaf” must appear clearly on the mail, accompanied by verifiable contact information (phone number, email address ending in @inserasaf.org). Without these elements, caution is advised.
Suspicious Mail from 75019 Paris: Warning Signals
Cybermalveillance.gouv.fr and the DGCCRF, through the SignalConso system, recommend considering any mail presented as “administrative” without referring to an official site or public register as suspicious. This principle directly applies to mail received from 121 rue Manin.
Elements to Check on the Received Mail
- The presence of the full name of the organization (Inser Asaf, and not an approximate variant or a truncated acronym) with a reachable phone number.
- The absence of a direct payment request: an accredited domiciliation association does not demand bank transfers by simple mail.
- The consistency between the subject of the mail and the actual services of the association (domiciliation, social support, food aid, clothing aid, orientation towards employment or housing).
- A reference to a verifiable official site: the site inserasaf.fr or inserasaf.org, and not a fanciful URL.
If the mail requests sensitive personal information (social security number, bank details) unrelated to an ongoing process, do not provide any data before verification.
Contact Inser Asaf Directly
The most reliable method remains a phone call to the number published on the official website of the association. The reception can confirm whether mail has indeed been sent in your name and in what context. This process takes a few minutes and removes any ambiguity.

Verification of the SIREN Number and the Register of Associations
To go further, the site annuaire-entreprises.data.gouv.fr allows you to search for the association by its SIREN number. Inser Asaf is listed under SIREN 440060762. This verification confirms the legal existence of the structure, its date of creation, and its declared address.
The SIREN alone does not prove that the received mail actually comes from the association. It proves that the organization exists and is registered. The combination of a valid SIREN, verified domiciliation accreditation with the prefecture, and direct phone confirmation constitutes the strongest level of verification.
Legitimate mail from Inser Asaf falls within the scope of its missions: reception, information, orientation, food and clothing aid, support towards housing, employment, or health. Any mail that falls outside this scope deserves thorough verification before any response.
The reliability of a letter cannot be read on the envelope. It is verified by cross-referencing the identity of the sender, the legal status of the organization, and the consistency of the content with the services actually offered at 121 rue Manin.
