Legal update · 1 October 2026
The Supreme Court annulled the state Single Rental Registry procedure established by Royal Decree 1312/2024. The judgment was issued on 19 May 2026 and published in the BOE on 8 June 2026. Obtaining the state NRA/NRUA number under that procedure is no longer required. Regional licences and registrations and guest registration obligations remain applicable.

Welcome to RegistroParteViajeros.com. In this article we explain simply and in detail what the Rental Registration Number (NRA, Número de Registro de Alquiler) is and how to obtain it. It has been a mandatory procedure since July 2025 for all owners offering short-term tourist accommodation in Spain.

What is the Rental Registration Number (NRA)?
The rental registration number (also known as the single rental register or NRUA) is an official national identifier, managed through the Single Digital Window for Leases (Ventanilla Única Digital de Arrendamientos), required to rent your home on platforms such as Airbnb, Booking, Rentalia, VRBO and others. It has been mandatory since 1 July 2025 to be able to list your accommodation.
Unlike the old regional licence number (which is still required), the NRA is a unique identifier that can be up to 53 characters long, and it allows authorities and booking platforms to instantly verify that your property meets all legal requirements, both national and municipal.
Why has it been mandatory since July 2025?
This single register pursues three clear objectives:
- Fighting the informal economy: ensuring that all accommodations pay their taxes correctly.
- Public safety: making it easier to cross-check data with the Ministry of the Interior.
- Planning control: preventing homes from operating in communities of owners that have prohibited it.
In addition, without this number you will not be able to advertise your property on online booking platforms, which provides security and transparency for both owners and guests.
The critical link between the NRA and the traveler report
Since Royal Decree 933/2021 came fully into force, the collection of guest data has become much stricter. It is no longer just the ID and the arrival date that are recorded; the administration now requires a full link between the accommodation and the transaction.
Identification in SES Hospedajes: when you send your traveler reports through platforms such as Registro Parte Viajeros, the registration number is the piece of data that links that report to your specific licence. Without a valid, up-to-date number, the submission to the authorities (Ministry of the Interior through SES Hospedajes) could be rejected, leaving you in breach of the law.
Booking verification: current regulations require reporting not only who enters the home, but also the booking and payment details. The NRA acts as your home’s “ID card” in each of these online submissions.
How to obtain the Rental Registration Number – step by step
1. Go to the official website of the Registradores de España
Go to the official page of the Registradores de España (Spanish Land Registrars).
2. Select the Rental Registration Number option
On the website, find the “Número de registro de alquiler” (rental registration number) section and select “Presentación telemática” (online submission).
3. Identify yourself as a subscribed user
There are three ways to identify yourself:
- Electronic certificate.
- Electronic ID card (DNIe).
- Subscribed user (usuario abonado).
We recommend the subscribed user option, because with an electronic certificate you will not be able to complete the procedure if you are not subscribed.
4. Register as a new user
Click “Eres nuevo, regístrate aquí” (new here? register) and follow the steps to subscribe:
- Select the third option: submit a document online (in this case, the application for the single registration number).
- Fill in your personal and bank details.
- Accept the terms of use.
- Set a username and password.
- Confirm your email with the code you will receive.
5. Log in with your username and electronic certificate
Once registered, log in to the Registradores website with your username and electronic certificate:
- Select the user you have just created.
- Go to the rental registration number and online submission section.
6. Submit the document
- Select the land registry office.
- Choose “Nueva presentación” (new submission).
- Document type: private document.
- Type of operation: assignment of a rental registration number for short-term rentals.
7. Download and fill in the application form
Download the application form and fill in all the fields:
- Land registry details.
- Property address.
- Applicant’s identification.
- Unique registry code (CRU) – you will find it in the title deeds or in a land registry extract (nota simple).
- Cadastral reference – if you don’t have it, see our explanatory video.
- Maximum number of tenants.
- Lease category.
- Landlord’s type of residence.
8. Attach the documents
Attach the form and the additional required documents:
- Responsible declaration (declaración responsable).
- Regional licence.
9. Review and send the application
- Review all the details.
- Attach the signed documents.
- Confirm the submission and send the application.
10. Receive the provisional registration number
After sending the application, you will receive a provisional single rental registration number by email. The land registry will then ratify it and notify you of the final number. Remember to pay the corresponding fees (approximately €27 + VAT).
Important: if you rent your property under two different arrangements (for example, holiday rental in summer and seasonal rental in winter), you must apply for two different registration numbers.
Penalties for non-compliance: what to avoid
Operating without the registration number or not including it in traveler reports can have serious consequences:
| Offence | Consequence |
|---|---|
| No number on platforms | Immediate blocking of the listing on Booking/Airbnb. |
| Not reporting traveler data (RD 933/2021) | Fines that can range from €601 to €30,000. |
| Misleading advertising | Administrative penalties from your region’s Tourism authority. |
