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.

What is the NRA and the Ventanilla Única Digital?

• 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.
• The NRA (Número de Registro de Alquiler) is a unique identifier that every property used for short-term rentals must have to be listed legally on any rental platform, including Holidu.

Tips

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

Yes. Just make sure that you meet the following requirements:

• Attach a document to your application that proves you have legal authorization (e.g. 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 the Consell’s registry, it will be accepted during the NRA application process. Having a temporary license simply means it is subject to review, but it is still valid for applying for the NRA.

Where to find the Código Registral Único (CRU)?

It is a 14-digit numerical code that you can find in several ways, for example : 

• Nota Simple from the Land Registry; it can be requested via https://sede.registradores.org
• Through the Land Registry's Online CRU Finder: https://cru.registradores.org/
• Through a Property Deed (Escritura); in some cases it might be referred to as "Identificador único registral."

My Holidu account does not accept my NRA, it gives me an error, what do I do?

The NRA can have up to 53 alphanumeric characters and is composed of several fields that follow a specific structure.

If you get an error when trying to save your NRA in Holidu, make sure that the format is correct and that each part complies with the configuration indicated in the table below:
