What is the Digital Single Window and why do you need a Short-term rental accommodation Registration Number in 2025?

Starting July 1st this year, Royal Decree 1312/2024 introduces new regulations for the vacation rental sector in Spain, following European Union guidelines. The objective is to enhance traceability and transparency through the Digital Single Window for Rentals, a system in which each property must obtain a Short-term rental accommodation Registration Number (NRA). Below we answer the most frequently asked questions about this important regulatory change and how to comply with the new requirements.

1. What is the Digital Single Window for Rentals and the Short-term rental accommodation Registration Number (NRA)?

The Digital Single Window for Rentals is a centralized platform, managed by the Ministry of Housing and Urban Agenda, that allows short-term rentals in Spain to be registered and monitored in a unified way.

The NRA is the mandatory identifier that each accommodation must obtain in order to be legally offered on vacation rental platforms.

The NRA is not the same as your touristic license: it’s a different number that complements your property’s touristic license.

The NRA can be up to 53 alphanumeric characters and looks something like this: ESFCTU00004501300010949200000000000VUT-4501-232-00018

It can be found in the PDF link emailed to you after having submitted your application:

2. How much does a NRA cost?

The cost to apply for the NRA online through the Registradores portal is 27 € per submission (before taxes or any applicable withholdings).

You can choose between two payment methods during the online application:

Credit or Debit Card (“Pago Telemático”)
- The simplest option for most Hosts.
- You can pay directly on the website using a Visa or Mastercard.
Prepaid wallet (“Monedero Registral”)
- Commonly used by professionals who regularly interact with property registries (eg. to pay for documents like a “nota simple”).
- This payment method requires you to top up your digital wallet with a minimum of 150€.

3. Is the €27 fee a one-time payment or do I need to pay it annually?

The €27 fee is an annual charge and must be paid each year upon renewing the NRA

4. To renew my NRA do I need to submit a new application every year or just pay the €27 fee?

Renewal requires both the payment of the €27 fee and a simplified renewal application. The renewal process typically involves confirming or updating existing information but is not as extensive as an initial registration.

5. Why is this law being introduced?

Royal Decree 1312/2024, based on EU Regulation 2024/1028, aims to:

Increase transparency and traceability in the short-term rental market.
Combat illegal rentals and unauthorized operations.
Create a safer environment for both hosts and travelers, ensuring quality and proper tax compliance of short-term accommodations.

6. Who is affected by this regulation?

Hosts (individuals or companies) offering short-term accommodations in Spain in exchange for remuneration.
Digital rental platforms operating in Spain, regardless of where their headquarters are located.

7. What types of properties are impacted by this regulation?

The regulation applies to all properties offered for short-term rental for profit, regardless of whether they are located in urban or rural areas.

This includes, but is not limited to:

Urban vacation rentals (Viviendas de Uso Turístico, or VUT)
Rural accommodations such as casas rurales
Individual rooms (habitaciones) offered within a home
Boats or other non-traditional lodgings, if rented for tourist purposes

If your property is being rented out to tourists on a short-term basis — whether it’s a standalone unit, shared room, or rural property — and you have a valid tourism license, then the regulation generally applies, and you will need to obtain the Número de Registro de Alquiler (NRA).

8. What types of properties are excluded from this regulation?

The following are excluded from this regulation and do not require an NRA:

Properties that are officially registered under tourism categories such as:
- Hotels, aparthotels, motels
- Guesthouses, hostels, or similar
- Campsites, caravan areas, or regulated rural hotels

These typically fall under NACE Rev. 2 categories 55.1, 55.2, or 55.3, and are subject to a different regulatory framework.

If your property is exempt from the regulation, you will soon be able to specify this in your Holidu account.

9. How can I check if my property is subject to this regulation?

Review the classification on your tourist license issued by your regional tourism authority.
If it’s listed as a hotel, hostel, campground, or another official tourism establishment (not a “vivienda de uso turístico”), you are likely exempt.
You can also verify this by:
- Checking your listing in your region’s tourism registry, or
- Contacting your local or regional tourism office for confirmation.

10. Do I need an NRA if I only rent out my property a few months per year?

Yes. How the property is used — not how often — determines if an NRA is required. If you're renting it out for financial gain, even for just a couple of weeks or months per year, you must register and obtain an NRA.

11. Do I need two NRAs if I offer both short and long stays?

No. If the rental is offered as short-term accommodation for payment, you only need one NRA per unit regardless of the length of stay.

12. When does the law come into effect and what is the deadline?

The regulation took effect on January 2, 2025.

There is a grace period until July 1, 2025.

Before that date, all hosts must have obtained an NRA and communicated it to the platforms

13. What are the main obligations for hosts?

Obtain a Short-term rental accommodation Registration Number (NRA) for each unit you offer.
Keep your information updated: if you change capacity, ownership, or other features, you must report it.
Respond to authorities regarding inspections or information requests.
Include the NRA in every platform where your property is listed. Otherwise, the platform will not be able to keep your listing active.

14. How do I obtain a Short-term rental accommodation Registration Number (NRA)?

You can find the process in detail in this video (in Spanish) or this PDF (also in Spanish).

1. Gather the required documentation*:

Unique Registry Code (“Código Registral Único” or CRU)
Cadastral Reference (or Boat ID number if applicable)
Tourist license or authorization (if required by your region)

*You must upload copies of the documents, not only the corresponding reference numbers.

2. Access the Electronic Headquarters of the College of Registrars.

3. Register here if you don’t already have an account and select the 3rd option “Electronic submission of a document” (”Presentar telemáticamente un documento”).

4. Identify yourself with your digital certificate and complete the application: “Assignment of Short-term rental accommodation Registration Number for Short-Term Rentals” (““Asignación de Número de Registro de Alquiler de Corta Duración”).

5. Sign and submit the documentation online via “Telematic Submission” (“Presentación telemática"”).

6. You will receive an email with a link to download the provisional NRA from the Electronic Headquarters. Once validated, its status becomes permanent and you will receive an email notification.

If you submit the application and do not receive an email with the provisional NRA, you can call the respective registry office. The registry staff must provide a CSV code that you can enter along with your ID number on the Sede Registradores website in order to download the document with the provisional NRA.

15. Can the NRA application be submitted in person, or must it be done online?

The application can be submitted electronically via Sede Registradores or in person at the “Registro de la Propiedad” or the corresponding office for “Bienes Muebles”.

16. Where can I find my Unique Registry Code (“Código Registral Único” CRU)?

The CRU is a 18-digit numeric code you can find:

On the Simple Note (“Nota Simple”) from the Property Registry. If you don’t have it, you can request it online from the College of Registrars: https://sede.registradores.org
In your property deed
On your property tax bill or receipt (“Impuesto sobre Bienes Inmuebles” or IBI)

In some cases your CRU may appear as “Identificador Único Registral” (IUR) or “Identificador Único de Finca Registral” (IDUFIR).

Your CRU is not the same as a cadastral reference or license number - it is a different, separate number.

17. Can I apply for an NRA if my property only has a temporary license number?

Yes. As long as your license is currently active in the Consell, it will be accepted during the application process. A temporary license is still valid, even if under review.

18. I have several units under the same license number. Can I apply for multiple NRAs with the shared license?

Yes. As long as the units legally operate under the same license, you can apply for an individual NRA for each one using the shared license number.

19. Can I apply for an NRA on someone else’s behalf (e.g. if I’m a property manager or agency)?

Yes. But you must:

Attach a document proving legal authorization (e.g., a notarized power of attorney or signed authorization).
Indicate the owner’s name in the “Person represented by the applicant” field of the form (“Persona a la que representa el interesado”).

20. How long is the NRA valid and do I need to renew it?

The NRA is valid for 12 months and is renewable if the rental activity continues. You’ll need to renew it annually, but the number itself won’t change.

21. What if I have multiple properties?

You must apply for an NRA for each unit you rent.
If multiple units share the same CRU (e.g. apartments in one building), you can apply for multiple NRAs in one application by detailing each unit.
In Holidu, you must enter the NRA for each individual unit.

22. I have a listing that combines two separate units rented together. Do I need a separate NRA for this combined listing?

No. You cannot obtain a separate NRA for the combined listing unless the two units are legally registered as a single property. However, you can still publish a combined listing, provided you follow these steps:

Obtain an individual NRA for each unit.
In the combined listing, clearly state that the rental includes both registered units.
Display the NRA of one of the units in the listing

Check with your regional tourism authority to confirm that this combined-listing setup is accepted in your Autonomous Community. Some may have specific guidance or require additional declarations.

23. What happens if I don’t get the NRA before July 1, 2025?

By law, platforms (including Holidu) might have to deactivate any listing without a valid NRA starting on that date. Your accommodation won’t be visible or bookable online until you obtain an NRA.

24. What about future bookings if I don’t get or renew the NRA?

Future reservations do not need to be cancelled if they were made through a valid listing at the time of booking (either with a valid NRA after July 1, 2025 or without an NRA before the regulation took effect).

25. I’m a Holidu Host. What are the steps I need to follow?

Obtain your NRA as soon as possible by following the steps above.
Log into your Holidu account.
Click on “Check the list” in the homepage banner and enter the NRA(s) you received (even if provisional) for each unit.
Or go to the “Properties” section and enter the NRA in the “Short-term rental accommodation Registration Number” field under “General Information.”

26. What if I don’t have a certificate of occupancy (“cédula de habitabilidad”)? Will I lose my license?

No. Licenses will not be revoked due to missing certificates of occupancy.

Many tourist licenses were issued for properties without this certificate. If your license is included in the Short-term rental accommodation Registration Number system, your property can claim grandfathered status due to long-term activity and request an exemption. This allows you to keep your license and obtain an NRA.

27. My Holidu account won’t accept my NRA — it shows an error. What do I do?

The NRA can be up to 53 alphanumeric characters and follows a specific structure.

Screenshot 2025-05-27 at 18.46.18.png

If you see an error while saving the NRA in Holidu, make sure the format is correct and all parts comply with the specifications highlighted in the table below:

28. What happens if my touristic license expires, is revoked, or cancelled?

To legally operate, a property needs both a license number and NRA. As a result, if either one is cancelled or becomes invalid, it must be renewed, otherwise the property will no longer be able to be published online.
