How to get your Airbnb registration number in 2026

You list your accommodations on Airbnb, reach the final step, and encounter a mandatory field that seems to hold everything up: the registration number. Without it, you can't complete the listing, and if you already have an active registration, you'll be notified that it will no longer be displayed. The question is always the same: how do you get an Airbnb registration number, and who provides it? Let's break it down step by step, explaining what has changed in 2026 and why that same number works on any platform, not just Airbnb.

Let's clear something up from the start, because that's where most of the confusion lies: there is no such thing as an "Airbnb registration number." Airbnb doesn't issue or manage it. The number is given to you by your regional government when you register your property as tourist accommodation, and Airbnb only asks for it to display in your listing. Understanding this will save you from searching in the wrong places.

What is the registration number that Airbnb asks for?

The registration number is the code that proves your property is registered as tourist accommodation with your autonomous community. It's a string of letters and numbers—each region has its own format—that identifies the property in the official census and that you must display in every listing you publish.

Airbnb, like other platforms, is required to ask for this code and remove listings that don't include it. That's why it appears as a required field: it's not a whim of the platform, it's a legal requirement that Airbnb passes on to the owner. The registration number is, in practice, the permit that makes your property a listing.

It's important to separate two often-confused concepts. One is obtaining the rental authorization, which you get by registering with your region's tourism registry. The other is adding that registration number to Airbnb, which is the final and simplest step. The first part is relatively time-consuming; the second takes only five minutes. Everything that follows focuses on successfully completing the first step.

What changed in 2026: goodbye to the "unique" registration number

If you've read that a unique national registration number was required to list on Airbnb starting in July 2025, that information is only partially accurate. The system did exist: Royal Decree 1312/2024 created the Unique Rental Registration Number, managed through a Digital One-Stop Shop, and it was launched on July 1, 2025, with the aim of giving each property a state code required on any platform.

But in May 2026, the Supreme Court, in its ruling 620/2026, annulled this single state registry. The reason is a matter of jurisdiction: tourism is regulated by the autonomous communities, and a national census that overlapped with theirs encroached upon their territory. You can consult the affected regulation in the Royal Decree 1312/2024 published in the BOE.

What does this mean for you in practice? It means you no longer need to obtain any state number or register the property in the Land Registry. ProMercy to advertise. The registration number you need for Airbnb is the one from your autonomous community, the usual one. Fewer offices, same fundamental requirement.

If you applied for the national number back then, keep it in mind, but don't worry too much: the one that actually allows you to advertise is still the regional number. That's the one you should focus on.

How to get your Airbnb registration number, step by step

Since your regional government issues the number, the process is carried out with them, almost always online, and in most regions, by submitting a sworn statement that authorizes you to do so at the time of submission. These are the steps, with the expected variations depending on the region.

1. Identify your community and its registry. Each region has its own tourism registry and its own name for the registration number. Locate the relevant tourism department or directorate; for example, in Andalusia, the process is carried out at the headquarters of the Andalusian Regional GovernmentIt is the starting point of everything.
2. Gather the property documentation. Cadastral reference, owner details, exact address, and, depending on the region, a certificate of occupancy or first occupancy license. Having this information on hand before starting will prevent you from interrupting the process midway.
3. Check the technical requirements. Many communities require ventilation or air conditioning, a fire extinguisher, a first-aid kit, and complaint forms. Check your tourist registration details before declaring anything, because you're declaring that you already comply.
4. Submit the declaration of responsibility. It's processed through your regional government's online portal, usually with a digital certificate or password. Once registered, you'll receive a registration number and, with it, authorization to start advertising.
5. Save the number and keep it handy. You'll need it on Airbnb, any other platform, and your own direct booking channels. Copy it exactly, in its exact format, because the platforms validate it.

A warning that many people overlook: if your property is in a homeowners' association, check the bylaws. Since 2025, a three-fifths majority of the residents has been able to limit or restrict tourist rentals in the building, and this restriction is independent of the registration number. You can have the correct registration number and still find yourself in conflict with the bylaws, so it's advisable to check them before taking any action.

What documents do you need for the registration number?

Although each region has its own list, there's a set of documents that's common to almost all registration number procedures. Having them ready before accessing the online portal is what turns the process into a matter of minutes instead of a puzzle.

• DNI or NIE in force of the holder who submits the declaration.
• Title proving the availability of the property: deed of ownership or contract that authorizes you to operate it as tourist accommodation.
• Cadastral reference of the property, which you can find on the IBI receipt or at the Cadastre office.
• Certificate of occupancy, which confirms that the property meets the conditions to be occupied.
• Energy efficiency certificate and, depending on the community, liability insurance or a plan of the property.

A practical tip: first download the official form from your regional tourism office. This form always includes the exact list of requirements for your registration number, so there won't be any last-minute surprises that force you to start from scratch.

How to add your Airbnb registration number

With the number in hand, listing it on Airbnb is the easy part. The process is as follows, with slight variations depending on the app version:

1. Log into your Airbnb account and open the listings section.
2. Choose the accommodation you want to edit.
3. Look for the section on regulations, laws and licenses in the advertisement.
4. Enter the registration number exactly as your community gave it to you, respecting letters, hyphens, and numbers.
5. Save the changes and repeat the process for each of your properties.

If you manage multiple properties, remember that each one has its own registration number: it's not shared between properties, even if you're the registered owner for all of them. Using the registration number of another property in a listing is an irregularity that both platforms and inspections easily detect.

You'll enter that same number into Booking.com or any other platform, in the corresponding field. That's why it's important to save it from day one: you enter it once for each channel and then forget about it.

With your registration number in order, you can advertise wherever you want, including on a channel with no booking fees. The Home Cake You pay a fixed monthly subscription and each booking goes entirely into your account, without the platform taking a percentage of each night.

The registration number community by community

The name of the registration number changes depending on where your home is located, although the function is identical. This is a quick reference; for detailed requirements and deadlines for each region, please refer to the relevant section. Complete guide to tourist registration in Spain, which we expanded with this year's changes.

The table is a guide, not a substitute for your local regulations. Each region sets its own requirements and method for assigning the number, so the first step is always to check what applies to you. And be aware of areas with high tourist traffic—Barcelona, ​​parts of the Balearic Islands, or certain neighborhoods in Málaga and San Sebastián—: some have closed or limited new registrations, so it's advisable to confirm that your area allows registration before buying or renovating a property to rent.

How much does the registration number cost and how long does it take?

The direct cost of the registration number is low or nonexistent in most regions: the declaration of responsibility itself usually has no fee, or only a nominal one. What might add to the cost is preparing the property to meet the requirements—a fire extinguisher, an identification plaque, adapting some details—and, if you delegate the process to a management company, their fees. None of this depended on the now-defunct state registry: these are regional requirements that remain unchanged.

Regarding timelines, with a self-declaration, authorization is immediate or takes only a few business days: you submit it and you'll have the number to list on Airbnb. If your community requires a prior licensing procedure, expect weeks instead of days, because the administration must review and authorize it before you can open. Knowing in advance which of the two systems applies to you allows you to plan when your listing will be live.

Two obligations that accompany the registration number and should be fulfilled from the outset are: displaying the identification plaque or sign if required by your local council, and registering guests on the traveler report submitted to the authorities. These aren't part of obtaining the registration number, but they go hand in hand with tourist rentals and will save you from unpleasant surprises during an inspection.

What happens if you list on Airbnb without a registration number?

Listing without a registration number isn't a shortcut, it's a costly risk. The most immediate consequence is applied by the platform itself: since you can't display a valid code, Airbnb removes the listing or simply won't let you finish it. Your property disappears from the listings just when you were expecting to start receiving bookings.

The second consequence is determined by your autonomous community. Renting without the corresponding registration is classified as an infraction under the tourism regulations of each region, with penalties ranging from a few hundred to tens of thousands of euros depending on the community and the severity of the offense. This isn't just a theoretical warning: inspections cross-reference data from online platforms with regional censuses, and an advertisement without a registration number is the easiest red flag to spot.

In contrast, obtaining a registration number is inexpensive and, in most regions, quick. It pays to do it right from the start rather than risk a fine that could wipe out years of savings.

Your registration number isn't just for Airbnb

Here's the key takeaway: your listing number isn't "Airbnb's." It's yours, it's linked to your property, and it allows you to list it wherever you want. Airbnb is just one more channel; with the same number, you can be on multiple platforms simultaneously and even sell your listings independently.

And that's where the cost of each channel comes in. On the major portals, you pay for visibility with a commission on each booking, month after month, as long as you own the property. We break it down in our guide on the Airbnb commission, with examples of how much is spent on each stay.

With all your paperwork in order, you're not obligated to rely solely on those portals. You can add a direct booking channel that doesn't charge you per night sold, where the margin that is currently spent on commissions It stays with you, and so does the relationship with the traveler. The registration number gives you legal standing; the channel you choose determines how much of your earnings end up in your account.

Think of it in terms of your channel portfolio. Airbnb gives you reach, but every booking that comes through Airbnb comes with its commission deducted. A direct booking channel adds its own reach without that recurring discount, and it doesn't compete with your presence on the portals: it coexists with it. The registration number is the same for everyone, so diversifying doesn't cost you any extra paperwork.
