What is the Unique Registration Number NRA and how does it affect my listing in Spain?

If you're offering short-term rentals in Spain, it's now mandatory to register your property through a new national system and obtain a Unique Registration Number (NRA) for each unit. This guide explains what the NRA is, why it matters for your listing, and how to obtain and upload it to your Holidu account.

Understanding the NRA and Ventanilla Única Digital

The Spanish government has implemented a centralized registration system for all short-term rental properties. Here's what you need to know:

What is the Ventanilla Única Digital de Arrendamientos?

The Ventanilla Única Digital de Arrendamientos is an official platform created by the Spanish Ministry of Housing. It centralizes the registration of all short-term rental properties in Spain, ensuring that every property meets legal requirements and is properly documented.

What is the NRA (Número de Registro de Alquiler)?

The NRA is a unique identifier that every property used for short-term rentals must have to be listed legally on any rental platform, including Holidu. Without an NRA, your property cannot be legally rented on any platform in Spain. This number is essential for compliance with Spanish housing regulations and is required for each individual property or unit you operate.

How does the NRA affect my listing in Spain?

The NRA is a legal requirement that directly impacts your ability to list and operate your rental property. Here's how:

Legal compliance: You cannot legally list short-term rentals in Spain without an NRA
Listing visibility: Your property may be delisted or visibility may be reduced if you don't provide a valid NRA
Booking permissions: Properties without an NRA cannot accept new bookings on rental platforms
Regulatory requirements: The NRA must be displayed on your listing and in all advertising materials

Special circumstances and FAQs

Can I apply for an NRA on behalf of someone else?

Yes, if you're a property manager or agency, you can apply on behalf of the property owner. To do this:

Attach a document proving you have legal authorization (such as a signed authorization with certified signature or a notarized power of attorney)
Indicate the property owner's name in the "Person represented by the applicant" field on the form

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

Yes. As long as your license number is active in your region's registry, it will be accepted during the NRA application process. Having a temporary license means it's subject to review, but it remains valid for NRA application purposes.

Where can I find the Código Registral Único (CRU)?

The CRU is a 14-digit numerical code that you can obtain through several methods:

Nota Simple from the Land Registry, requested via https://sede.registradores.org
The Land Registry's Online CRU Finder: https://cru.registradores.org/
Your Property Deed (Escritura), which may refer to it as "Identificador único registral"
