CIN, the national identification code: what changes for a hospitality business

Anyone running a hospitality business who hears about the CIN usually starts from the wrong question: «is this one more thing I now have to do?». The question that actually matters is different: the code your region most likely already assigned you, did it turn into a CIN on its own, or is it on you to go get one? And above all: are you displaying it everywhere the law says it must appear, including your own website, not just on the booking platforms?

What the CIN is, and who needs one

The CIN, Codice Identificativo Nazionale (National Identification Code), comes from article 13-ter of decree-law no. 145 of 18 October 2023, inserted when the decree was converted into law 191 of 15 December 2023. It is issued by Italy's Ministry of Tourism, through an automated procedure, to three categories: residential units rented out for tourist purposes, units rented out under Italy's short-term rental rules, and hotel and non-hotel tourist accommodation facilities as defined by regional and provincial regulations.

If you run a hotel, a B&B, or a guesthouse, you fall into that third category. It's worth stressing this, because public discussion of the CIN almost always focuses on short-term rental apartments: in the text of the law, your property is covered exactly the same way those apartments are, with the same display requirements and the same fines.

If your region already had a code, the switch is automatic

Several Italian regions and autonomous provinces already ran their own identification-code systems before the CIN, often called CIR or CIU. For these properties, the law doesn't require a fresh application: the regional or provincial authority itself must automatically recode the identifiers it had already issued, adding an alphanumeric prefix supplied by the Ministry of Tourism, and transmit the resulting CINs to the national database.

So the switch isn't something you need to act on. What stays on you is checking it happened: open the National Database of Accommodation Facilities (Banca Dati Nazionale delle Strutture Ricettive, BDSR) and confirm your property shows up with an assigned CIN. If it doesn't, there's a procedure set out by the Ministry of Tourism decree of 6 June 2024: the «missing property report». Once you file it, you get thirty days during which the Ministry reviews your case and during which you cannot be fined for lacking the code, even while the review is still open.

If your region never had its own code, or if your regional code hasn't been recoded within the expected timeframe, the application has to be filed directly through the Ministry's online portal, with a declaration stating the property's cadastral data.

Where it has to appear, and not only on the booking platforms

This is where the most common misunderstanding sits, and the law is direct about it. Whoever runs a tourist accommodation facility «must display the CIN outside the building» where the unit or property is located, respecting any planning or heritage restrictions on the sign or plaque, «as well as state it in every advertisement, however published and communicated».

«Every advertisement, however published» doesn't distinguish between channels: it covers your own website, your property's page on your own booking engine, your social media profiles, your Google listing. It's an obligation that falls on you, the owner, before it falls on whoever distributes your listings on your behalf.

Platforms and real-estate intermediaries carry a second, separate and additional obligation: they too must state your property's CIN in every advertisement they publish. The two obligations stack, they don't substitute for each other: the fact that Booking or another platform already shows your CIN does not excuse your own website from showing it as well.

The deadlines, after the past postponements

The law itself, in paragraph 15, ties its entry into force to a notice: the provisions apply starting from the sixtieth day after the Official Gazette publishes the notice confirming the national database and the CIN-assignment portal have gone live. That notice was published in September 2024, triggering the obligation in early November 2024. The Ministry of Tourism, according to converging reports from multiple professional sources in the sector, then granted a technical extension that moved the deadline to acquire and display the code to 1 January 2025, with fines applicable from the following day.

No further postponement has emerged since that extension, despite a targeted search through all the news of 2025 and 2026: the obligation has been fully in force and enforceable for nearly two years as of this writing. Anyone who has put off compliance expecting another extension, as there have been on this exact topic before, is working on an assumption that currently has no support.

The fines, and one point not to confuse

There are two distinct fines for the CIN, differing in amount and in what triggers them:

Checking and fining falls to the municipality where the property is located, through the local police: the proceeds stay with the municipality, earmarked for tourism initiatives and waste management.

The point not to confuse this with is the SCIA (certified start-of-activity notice), which comes from the same article of law but is a separate requirement: it applies to whoever runs a tourist rental as a business and is filed with the municipality's one-stop business desk, carrying its own fine of 2,000 to 10,000 euros if missing. For a hotel already licensed under the ordinary regional rules, this second fine usually isn't the issue; it is for whoever runs short-term or tourist rental units as a business without ever having filed it.

The checking isn't only a municipal matter

Beyond the local-police checks on the two fines above, the national database also feeds a second layer of oversight aimed at tax enforcement: Italy's Revenue Agency and the Financial Police use it to identify, through risk analysis, whoever rents out or runs accommodation without a CIN. The dashboard that makes this possible, available to municipalities since 2025, was extended from June 2026 to these two authorities as well. So it isn't only about the plaque at the entrance: a property without a CIN sits more easily within reach of checks on rental income, not only within reach of administrative fines on its advertising.

Where to start

Three checks, in order: confirm your property appears in the National Database of Accommodation Facilities with an assigned CIN, and if it doesn't, file the missing-property report instead of waiting for someone else to notice. Then check your own website, your booking engine, and your social media profiles: the CIN needs to appear there with the same clarity it shows, or should show, on the platforms that list you. Finally, if you also run short-term rental units alongside your main property, check that you've filed the SCIA for that activity: it's a separate requirement with a separate fine, and it's common for whoever has solved the first problem to assume the second one is closed too.

It's also worth checking whether your management software helps you keep track of this kind of deadline alongside the other requirements a property has to meet, from guest identification to electronic invoicing: it isn't the only new regulatory requirement the sector has had to absorb over the past two years, as what recently happened around automated check-in also shows.

If you want someone to look at your website and your channels with this kind of check, along with everything else, there's the digital check-up, free if we then start with one of the monthly services. Otherwise write to me: tell me where you've already published the CIN and where you haven't, and I'll tell you what's missing.
