France, Italy, Spain and parts of the UK now require short-term rentals to be registered, with booking platforms enforcing the numbers and penalties running into thousands of euros. Several countries also require reporting every guest within 24 to 72 hours of check-in. This guide covers each regime, deadlines, documents and fines, and how Nowistay's AI connector helps pre-fill the forms.

Start free trialFor most of the last decade, registering a short-term rental in Europe was optional in practice. A host could list on Airbnb, take bookings, and worry about the paperwork later, if at all. That window has closed. Between 2024 and 2026, France, Italy, Spain, and parts of the UK each rolled out mandatory registration regimes with real penalties (thousands to tens of thousands of euros) and, crucially, enforcement that runs through the booking platforms themselves. An unregistered listing in 2026 is not a listing that flies under the radar, it is a listing the platform is legally required to remove.
The change matters because the enforcement model flipped. Old regulations relied on municipalities catching offenders one at a time, which rarely happened. The new regimes make Airbnb, Booking.com, and VRBO responsible for verifying a registration number before a listing can stay live, with the platforms facing their own penalties if they host unregistered properties. This guide walks through the four regimes host by host: what each requires, the deadlines, the penalties, the documents you need, and how the platforms enforce. It closes with what good registration management looks like across a portfolio.
Three forces converged. Housing pressure in tourist cities pushed local governments to track and cap short-term rentals. The EU’s broader transparency agenda (the DAC7 tax directive, the Short-Term Rental Regulation adopted in 2024) created a legal framework requiring registration data to flow to authorities. And the platforms, facing their own regulatory exposure, became willing enforcement partners rather than obstacles. The result is a coordinated push: register, display your number, or be delisted.
The EU Short-Term Rental Regulation (Regulation 2024/1028, adopted April 2024) is the umbrella. It sets common rules for the registration systems member states choose to run (hosts get a unique number), and it requires platforms to check those numbers and report activity data to authorities. Member states are implementing it on their own timelines, which is why France, Italy, and Spain each have a distinct system rather than one EU-wide registry. The regulation has applied since 20 May 2026, which is why so many national deadlines cluster around that date.
France’s framework was overhauled by the Le Meur law (loi Le Meur), promulgated on 19 November 2024. It tightens short-term rental rules across the board and introduces a national registration requirement. For the tax, day-cap and co-ownership changes that came with it, see our guide to the anti-Airbnb law.
The national service will centralize what is still a patchwork of municipal registration procedures (Declaloc is one service some communes use). Hosts enter property details, ownership, and the primary-versus-secondary-residence status, and receive the 13-character number to paste into each listing.
Italy introduced the Codice Identificativo Nazionale (CIN), a national identification code for short-term and tourist rentals, under Decreto-Legge 145/2023. The system opened for registration on 1 September 2024 and became fully mandatory from 1 January 2025.
The CIN must appear in every online listing. Platforms operating in Italy check for it, and listings without a valid CIN are subject to removal.
Spain launched the Registro Único de Arrendamientos (NRUA), a single national rental registry operated through the Ventanilla Única Digital, and made it mandatory on 1 July 2025. In May 2026 the Supreme Court annulled the provisions that created it (Sentencia 620/2026), ruling that the State lacked competence.
Keep the regional number displayed on every channel: a listing flagged as non-compliant can disappear fast.
The UK does not yet have a single national registration scheme, but the pieces are arriving region by region, and England’s register is due to be running by March 2027.
UK hosts in Scotland should treat licensing as a live requirement today. Hosts in Wales must register before 31 March 2027, and hosts in England should watch for the register due by March 2027.
Registering the property is only half the obligation. Several countries also require the host to register every individual guest with the police or a national authority, usually within 24 to 72 hours of check-in. This is a separate, recurring duty that applies to each booking, not a one-time property filing, and it is easy to overlook because it sits outside the OTA listing flow entirely.
The practical pain is the frequency. Property registration happens once and renews occasionally. Guest registration happens on every single booking, often within a 24-hour window, and the forms ask for data the host has to chase from the guest after they have already arrived. At portfolio scale, this is one of the most time-consuming compliance tasks there is. Tourist tax is the other duty that lands on every booking, and collecting and automating it follows the same logic: one rule per property, applied automatically.
The exact list varies by country and municipality, but registration applications generally ask for:
The enforcement model is what makes these regimes different from past regulations. Rather than relying on municipal inspectors, the laws make the booking platforms responsible:
Free, and for a single property in a single jurisdiction, manageable. The host fills out the commune, CIN, or regional form, gets the number, and pastes it into each listing. The friction grows with each additional property and each additional country.
Many hosts delegate registration to the same accountant who handles their rental income tax. Cost is typically bundled into the annual accounting fee. Reliable for compliance, but the accountant rarely manages the day-to-day of keeping numbers displayed correctly in listings.
Airbnb and Booking.com have built guided flows that prompt hosts to enter the registration number and, in some markets, link to the registration portal. Helpful for awareness, but the host still has to obtain the number and keep it current across every channel.
Specialized firms handle registration, renewals, and ongoing compliance across multiple jurisdictions for a fee. Worth it for large or multi-country portfolios where tracking deadlines and renewals manually becomes a job in itself.
Registration is one of the areas where connecting an AI assistant to Nowistay does the heavy lifting. A host who has connected Claude or ChatGPT to Nowistay through the MCP server (see how to manage your vacation rental from ChatGPT or Claude) gives the assistant live access to the property details already held in Nowistay, the address, the cadastral reference, ownership status, the primary-versus-secondary-residence flag, and the amenity and safety inventory. From there the assistant can do the parts of registration that usually eat an afternoon:
The result is that the tedious data-gathering and form-filling collapse into a short review-and-submit. You still obtain and own the registration number through the official portal, Nowistay does not issue it or hold it on your behalf, but the work of getting there is largely automated. Start with the jurisdiction where a missing number would cost you the most: check that every listing there displays its registration number, then put each renewal or annual declaration date in your calendar so nothing lapses between two seasons.
This article is general guidance, not legal advice. Registration rules change frequently and vary by municipality. Confirm the current requirements with your local authority or a qualified professional before relying on any specific figure or deadline.
The hosts who treat registration as a one-time annoyance get caught by the 2026 deadlines and the short platform-takedown timelines. The hosts who treat it as a standing operational task, one record per property, displayed everywhere, renewed on schedule, keep their listings live while competitors scramble.
Yes. France requires a 13-character registration number displayed in every listing. It is mandatory today in communes that run a registration procedure (some use the Declaloc service), and the national online service planned for the fourth quarter of 2026 will extend it everywhere, with numbers issued by communes to be renewed on it. Italy has required the CIN national identification code since 1 January 2025, displayed in every listing and on-site. In Spain, the Supreme Court annulled the national NRUA registry in May 2026, so the regional tourism registration remains the reference. Each is enforced through the booking platforms, which check the number and remove non-compliant listings.
France: up to €10,000 for failing to register and up to €20,000 for a false declaration or fake number under the Le Meur law (Service-public's guide still lists the former €5,000 for failing to register, so confirm locally). Italy: €800 to €8,000 for operating without a CIN, €500 to €5,000 for not displaying it, and €600 to €6,000 per violation for missing required safety equipment. Spain: penalties for operating without the regional registration are set by each region's tourism rules. Scotland: operating without a short-term let license is a criminal offense with fines up to £2,500.
The new regimes make Airbnb, Booking.com, and VRBO responsible for enforcement rather than municipal inspectors. Each platform has a field where the registration number is entered and displayed, and in regulated markets a listing cannot stay fully live without a valid number. Delisting can be fast once an authority flags a listing. Platforms enforce proactively because they face their own legal obligations and penalties. Under the EU regulation and DAC7, platforms also report host activity to tax and housing authorities, so unregistered listings are visible to the state.
In several countries, yes, and it is a separate obligation from registering the property. Spain requires hosts to submit guest and booking data to the Ministry of the Interior through the SES.Hospedajes platform (parte de viajeros, Real Decreto 933/2021), typically within 24 hours. Italy requires reporting each guest to the State Police through Alloggiati Web within 24 hours of arrival. Portugal requires a boletim de alojamento for each guest, France requires a police information sheet for foreign guests, and Croatia's eVisitor requires registering every guest within 24 hours. Unlike property registration, this recurs on every single booking, which makes it one of the most time-consuming compliance tasks at portfolio scale.
