Declaloc Registration Number: A Host Guide to the 13-Digit Code

The Declaloc number is a 13-digit registration code issued for a French short-term rental property on declaration to the commune. It identifies that property's declaration, and it must be displayed on listings, with mandatory display from 20 May 2026. A host with three properties holds three numbers, one per property. A guest, a platform or a commune officer can use the number to match an advert to a declared property, which is the whole point of the system: adverts become traceable to declarations.

Hosts sometimes confuse the Declaloc number with a tax reference or a platform account number. It is neither. It is a property declaration identifier, issued through the commune declaration process, and it should be stored with the declaration confirmation, not with tax papers alone. Keeping it in the property file, alongside planning and condo notes, makes every later check faster.

Declaration is made to the commune where the property sits, through the process that commune uses, which may involve an online portal or a form. The host provides property and operator details as the commune requires, and receives the 13-digit number on completion. This guide does not list form fields, because communes vary and forms change; the commune portal for the address is the authoritative source. Prepare ownership and operator details and the property address as it appears in official records before starting.

If a declaration is refused or queried, the commune's message usually names the issue: an address mismatch, a missing document, or a property type question. Answer that specific issue rather than resubmitting the same details. Repeated identical submissions waste time and can create duplicate records that later need untangling. Keep the commune correspondence with the declaration confirmation.

Display means the number appears where guests and authorities can see it: on platform listings and in advertisements for the property. A number stored only in a host dashboard, or sent only to confirmed guests, does not meet a display duty. Hosts should view each listing as a guest would, confirm the number is visible, and repeat that check on every platform where the property appears, since display formats and field behaviour differ by platform.

Direct adverts need the same audit. A host's own booking page, a social media post, or a listing on a smaller site should all carry the number where the law requires display. Older adverts are a common gap: a post from before registration that still circulates online may lack the number long after the host has complied on main platforms. Sweep old adverts at least annually and update or remove them.

Mix-ups happen when a host copies a number across properties, when a manager uses one number for a portfolio, or when a property is reconfigured and the declaration is not updated. Each of those creates a false match between advert and declaration. The remedy is a simple table: property, address, Declaloc number, declaration date, listing links. Check the table against live listings monthly, and update it the day a number changes.

Property changes deserve a declaration check. A change in operator, a change from principal residence to second home use, or a significant change in the property itself may require an updated declaration. Do not assume an old number automatically covers a new use. Ask the commune whether an update is needed, and keep the reply with the property file.

When a platform cannot verify a Declaloc number, it may hold or suspend the listing. The usual causes are a typo, a number for a different property, a declaration that has not yet been processed, or a platform checking the wrong field. Diagnose in that order: compare the entered number digit by digit with the declaration confirmation, confirm the property match, confirm the declaration is complete, and only then contact platform support with the confirmation details.

While a listing is held, do not create a duplicate listing with a slightly different address to bypass the hold. Duplicates are often matched by photographs or address, and a bypass attempt can worsen account standing. Fix the number at source, confirm public display after reinstatement, and file the platform messages with the property record.

Registration is not a one-time event if the property, operator or use changes, and commune rules may require updates or renewals. Record the declaration date, any validity or renewal information the commune provides, and a recheck date. Before each season, confirm the number still displays correctly on every listing and that the declaration still matches the current use. That seasonal check takes minutes and prevents the most common Declaloc failure: a correct number that stopped displaying after an edit.

Verify current declaration steps on service-public.fr and the commune portal for the address. This guide is general information only, last verified on 26 October 2026, and does not replace commune guidance for a specific property.
