A household recognized as a DALO priority has been waiting for months without any housing proposal. The file is complete on the SNE (National Registration System). The problem often lies elsewhere: the registration in Syplo is absent, incomplete, or inconsistent with the recorded request. It is this link, poorly understood by applicants, that concretely blocks access to social housing for priority groups.
Syplo and SNE: understanding the relationship between the two tools
The SNE and Syplo are often confused because both concern social housing requests, but they serve different functions. The SNE records all social housing requests in France. Syplo, on the other hand, only concerns applicants recognized as priority in a given department.

Syplo is software shared between the State, social landlords, the SIAO, and Action Logement. It stores information from applicants labeled as priority (DALO, PDALPD, those exiting accommodation) and makes it visible to reservers who have relocation obligations. Without registration in Syplo, a priority file remains invisible to landlords.
When trying to speed up their social housing request with Syplo, the first step is to check that this registration actually exists and that the data matches that of the SNE. Field feedback shows that some households only receive proposals after correcting an absence or error in registration with the prefecture or the SIAO.

SNE-Syplo inconsistencies: the obstacle that no one reports to the applicant
The instructing services have identified a recurring problem: inconsistencies between SNE, Syplo, and the internal files of landlords slow down relocation. Specifically, if the family composition, resources, or desired municipalities differ between these three databases, the file falls into a blind spot.
Let’s take a common case. An applicant updates their family situation on the SNE (birth, separation) but does not inform the SIAO. Syplo retains the old data. The landlord, searching for a candidate for a T3, does not see this household that would actually need this type of accommodation. The file remains pending without anyone understanding why.
What can be checked independently
- Contact the SIAO of their department to request written confirmation of their Syplo registration and the information it contains
- Compare this data with that of the SNE form (number of people, declared income, requested municipalities) and report any discrepancies
- After each change in situation (employment, child, accommodation), follow up with both the SNE and the SIAO to ensure both databases are synchronized
This double-checking is never explained to the applicant during the initial submission. Feedback varies on this point depending on the departments, but the process remains relevant everywhere.
Syplo as a leverage for pressure on social housing reservers
Syplo is not just a digital waiting list. Since the gradual transition to flow management of contingents, the tool is also used to monitor whether reservers comply with their relocation obligations for priority groups. The State, Action Logement, and sometimes local authorities are directly monitored via Syplo.
For the applicant, this changes the game. When a social landlord consults Syplo to find candidates matching a housing available in the prefectural contingent, they work under pressure. They must prioritize households registered in the database. A well-informed file in Syplo, with broad search criteria (multiple municipalities, multiple types), has a mechanically higher chance of being selected.
Widening geographical criteria in Syplo
We often see applicants who restrict their search to a single municipality. By expanding to several cities in the department, the number of housing options on which the file can be positioned increases. This point is particularly sensitive in Île-de-France, where the demand varies greatly from one municipality to another.
To modify these criteria in Syplo, one must go through the SIAO or the instructing service (prefecture, housing service of the town hall depending on the department). The applicant cannot directly modify their data in Syplo.
Automatic DALO-Syplo registration: verify rather than assume
In several departments, Syplo registration is now automatic for households recognized as DALO, thanks to the link between the SNE and Syplo. In theory, no additional steps are necessary after the favorable decision from the mediation commission.
In practice, this automation does not always work. Applicants report on DALO forums that they discovered, sometimes after several months, that their Syplo registration had not been completed or was incomplete. Checking one’s Syplo registration after a DALO decision is a precaution not to be neglected.
- Request confirmation of registration from the SIAO or the prefecture in the weeks following the DALO notification
- Ensure that the unique departmental number is correctly listed in Syplo
- Verify that the housing criteria (size, location) match the actual situation of the household at the time of verification
Departmental Syplo procedure: each territory has its own rules
The operation of Syplo is not uniform across the entire territory. Each department defines its own procedure for labeling priority groups. Eligibility criteria, registration circuits, and involved actors vary.
In Hauts-de-Seine, for example, the labeling procedure under the PDALPD passes through specific modalities defined within the framework of the departmental action plan for housing disadvantaged people. In other departments, the SIAO centralizes registrations more. Inquiring about the exact procedure in one’s department avoids unnecessary steps.
The reflex to adopt: contact the departmental SIAO or the housing service of the prefecture directly to know the procedure to follow. Information found online rarely corresponds to the precise circuit of one’s territory.
A well-registered Syplo file, coherent with the SNE and positioned on realistic geographical criteria forms the basis of a social housing request that progresses. The tool remains underutilized due to a lack of clear information, even though it is the necessary step for landlords to identify priority households in their relocation obligations.
