A letter bearing the Inser ASAF letterhead and a shipping address in 75019 Paris regularly raises questions among its recipients. The association, active since 1984 in the fight against social exclusion, manages a significant volume of correspondence related to its domiciliation service. Quickly identifying whether such a letter is authentic requires knowledge of the verifiable markers specific to this organization.
Cross-reference the sender Inser ASAF through a third-party directory
The first verification to conduct does not concern the content of the letter, but the very existence of the sending entity. An independent business directory like Infobel lists Inser ASAF as an organization based in Paris, specializing in supporting homeless individuals. This cross-check confirms that the name, city, and industry mentioned in the letter correspond to a real organization.

We recommend cross-referencing at least three sources: the official site inserasaf.fr, the Infobel directory, and the profile accessible on annuaire-entreprises.data.gouv.fr. If all three converge on the same SIREN number, the same address, and the same declared activity, the legal existence of the association is confirmed.
To go beyond this first step and thoroughly verify a letter from Inser Asaf sent from 75019 Paris, one must examine technical elements specific to the document itself.

Domiciliation letter from Inser ASAF: authenticity markers
Inser ASAF offers a recognized domiciliation service aimed at individuals in precarious situations who need a stable postal address to access their rights. Letters issued in this context present recurring characteristics that an informed recipient can verify.

- The shipping address mentions Manin Street in the 19th arrondissement of Paris, consistent with the operational headquarters of the association.
- The letter refers to administrative support, guidance towards social services, or the receipt of official documents on behalf of a domiciled beneficiary.
- A phone number appears on the document (0985123978 is the number published on the official site). Any other number must be verified before returning the call.
- The subject of the letter concerns domiciliation, food assistance, professional integration, or access to rights, which aligns with the declared missions of the organization.
A letter from Inser ASAF requesting direct payment, providing an unknown bank account number, or demanding the transmission of identity documents by postal return without prior procedure falls outside the usual operational framework of the association. Any unsolicited financial request should trigger a verification by direct call to the official number.
Verification of the link between Inser ASAF and territorial coordination mechanisms
An often-overlooked element in public guides concerns institutional recognition. Inser ASAF appears in territorial coordination documents related to domiciliation and support for individuals in situations of exclusion. This presence in official social management circuits constitutes a legitimacy indicator that simple examination of the letter does not provide.
Specifically, if the received letter mentions follow-up related to a social integration mechanism or guidance towards a public service (health, social rights, accommodation), it is consistent with Inser ASAF’s positioning within the Parisian associative ecosystem. The association has been active in these areas for forty years, which excludes the profile of a temporary or fictitious structure.
We observe that fraudulent letters impersonating associations rarely use references to specific territorial mechanisms, as this information is difficult to reproduce without knowledge of the sector.
Contact the association directly to confirm the sending
The most reliable method remains direct contact. The site inserasaf.fr publishes a phone number and an email address ([email protected]). The association also has a mail space online via the DomiFa platform, a tool developed by the Digital Factory of the social ministries, used by accredited domiciliation structures.
If the association confirms the sending of the letter and the subject corresponds to your administrative situation, the document is authentic. If no one can confirm the sending, do not respond to any request contained in the letter.

Warning signs of a fake associative letter in 75019 Paris
Identity theft of associations exists, including for social purpose structures. Several signals should immediately raise alarms.
- The Inser ASAF logo is present but pixelated, distorted, or accompanied by a slightly modified name (letter inversion, addition of an unusual hyphen).
- The postal address differs from that published on the official site or in verified directories.
- The letter contains no reference to a file, a tracking number, or a named contact within the association.
- An artificial urgency is created: very short response time, threat of loss of rights without basis.
A legitimate letter from a domiciliation association always identifies the beneficiary by a file number or an internal reference. The complete absence of personalization is a strong signal of impersonation.
The reflex to adopt when faced with a suspicious letter remains the same regardless of the declared sender: never respond in haste, verify the existence of the structure through independent sources, and then contact the organization directly through the official channels published on its site. For Inser ASAF, the longevity of the structure, its presence in public directories, and its use of the DomiFa platform provide numerous concrete checkpoints before proceeding with any correspondence.
