The national short-let registry number was annulled: what an owner or buyer does now

§ 1The short version of what happened

If you let a Spanish home to tourists, or you are thinking of buying one that is let that way, you probably heard that a national registry number was introduced in 2025 and that the number is now gone. Both statements are half true. The decree behind the number was Royal Decree 1312/2024. In a judgment of 19 May 2026, published in the gazette on 8 June 2026, the Supreme Court annulled the provisions of that decree that created a single procedure for the number, and it dismissed the appeal on every other point. We wrote the legal summary on our summary of the judgment. This post is the practical companion: three situations an owner or buyer can be in, and what to do in each.

A word on how sure we are. We read the operative part of the judgment, the part that lists what is annulled. It names the articles removed: the first article as far as it covers the single procedure, parts of the second, the fifth to the tenth articles in the parts about the procedure, part of the twelfth, the second additional provision and part of the first final provision. We did not read the court's reasoning. Press and law-firm notes say the court found that the State lacks competence for a national register that sits over the regional ones. That is their reading, and we mark it as such wherever it appears below.

§ 2What the decree did, in one paragraph

The decree said an owner should ask for a number by electronic request to the registrars' professional body or on paper at the competent registry. The request had to give the address, the unique registry code and the cadastral reference, and the Property Registry handled it. In January 2026 the Directorate-General for Legal Security and Public Faith published a ruling saying that registrars had to check that a unit needing a licence-type authorisation had the title for the intended use before they assigned a number. That check is now part of a procedure the court annulled, and it is a good picture of the weight the number was meant to carry: a number was supposed to mean that someone had looked at the papers.

§ 3Case one: you already hold a number

You applied, a registrar assigned a number, and your adverts show it. Three questions follow.

Does the number still mean anything? Not as a national check. The procedure that produced it is annulled, and a number that came from it cannot show that a registrar looked at your papers under a valid national rule. What it means in practice depends on the platform and on the region. A law-firm note says the platforms' duty to send data to the authorities and the digital one-stop window stay in force, which suggests that platforms still collect an identifier. A consumer body says the one-stop window of the Housing Ministry remains. Neither statement comes from the judgment text that we read.

Is it void from the start or only from now? We do not know. A law-firm note from early June, written before the gazette publication, says that annulled provisions have general effect from the day of publication, which would make the date in the gazette the one that matters. That is a lawyer's statement about the general rule for such judgments, and it does not tell you what happens to a number issued in the past. No official source we could open does either.

What do you do with it? Keep it. Keep the application, the answer, the papers you attached and the screenshot of the number on each advert. The papers behind a number are the part that retains value, because your regional register, your municipality and your community will ask for the same things the registrar asked for. If a registry or platform later says the number is invalid, you want to show that you applied properly and held every title the unit needed.

§ 4Case two: a platform asks for a number, or a listing was taken down

Before the judgment, platforms removed adverts that did not show a national number, according to a consumer body. If that happened to you, the situation now is awkward, because the number the platform wanted came from a procedure that no longer stands. You have two jobs.

First, read the host help page of the platform and find which number it asks for in the country and the region where your home stands. A law firm tells owners and managers to check, property by property, which number each platform requires under the regional rules. We have not tested what each platform accepts, and its help pages change. Do not enter a number you do not hold, and do not invent one to get an advert back online.

Second, put the regional paper in order. The regional systems are where the number now comes from. We describe the main ones on separate pages: the Valencian register route for the Valencian tourist dwelling register, the Madrid papers for Madrid, and the other chapter pages for Andalusia, Catalonia, the Balearic Islands and the Canary Islands. A regional registration is separate from a municipal licence. A Madrid registrar refused a national number to an owner who held a regional registration from 2018 and no municipal licence, and the Directorate-General dismissed the appeal. The case shows two papers where an owner thought one was enough, and it applies whatever happens to the national number.

If a platform stays silent, ask in writing. Ask which identifier the listing needs, whether a regional number is enough, and whether the advert will be restored. A written answer is worth more than a call if a dispute follows.

§ 5Case three: you are buying a home that is let

Here the number is a sales argument. An advert says "registered, national number" and the agent says the income is secure. The ruling changes how much that line is worth.

A national number used to be a short answer to the question "is this letting legal?". It is no longer one. The questions that matter are the ones the chapter on the holiday rentals chapter sets out: a regional authorisation, a municipal licence or declaration, and permission under the building's own rules. Ask the seller for the three papers and ask your lawyer to check them. If the home is in a building with a community, add a fourth request: the community's approval.

That fourth paper has its own rule, and it did not move. Since 3 April 2025 the horizontal property law requires an owner who wants to carry on tourist letting to obtain the prior express approval of the community, and the president can require the activity to stop if it starts without that approval. Approving, limiting or prohibiting tourist rental needs the favourable vote of three fifths of the owners. The rules on the owners' vote cover the vote. Two registry resolutions published in the gazette on 9 July 2026 apply the rule and say that a tourist label in the title deed or statutes that favour tourist use are not express approval. The exception for owners already letting before the date is narrow. They are registry decisions, not court judgments.

For a buyer, the practical effect is this. Do not pay for the income history without the papers. If the seller cannot show the regional registration, the municipal paper and the community's position, price the home as a home, not as a business. If you make an offer on the strength of rental income, put a condition in the contract that the papers are delivered, and ask your lawyer how to word it. What platforms ask of a host is covered in how platforms treat tourist lets.

§ 6What the ruling does not change

It does not make letting legal where it was not. The judgment is about who may run a registry, not about whether a home may be let. The regional rules, the municipal licences and the community's approval apply as before. The judgment also does not tell owners that platforms will accept an advert with no number. Both points are easy to lose in the shorthand "the registry was annulled".

It does not by itself settle fines. A consumer body says that penalties for not entering the State registry should lapse and that an owner may have grounds to challenge a sanction. That is advice from a press article. We did not read the rules for appeals, and the periods for challenging a fine are short. If you have a notice, take it to a lawyer in your region at once.

§ 7A short list for this week

• Find the application papers for any number you hold, and save them somewhere other than the platform account.
• Open each platform's host help page and note the identifier it asks for, with the date.
• Check that your regional register entry and your municipal paper are current, and that both match the unit you let.
• If you live in a building with a community, find out whether the owners voted and keep the minutes.
• If you are buying, do not rely on an advert's number. Ask for the papers the number was supposed to stand for.

§ 8What we could not confirm

• We did not read the court's reasoning, only the operative part.
• We could not confirm from an official source how numbers already issued are treated, or from which day the annulment takes effect.
• We did not test what each platform accepts today.
• We did not read the appeal rules for fines.
• We read the registry decree only in part: its first article and part of its ninth.

Legal note. How the process works in general. It is not legal advice, and it never replaces an independent Spanish lawyer acting for you.
