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, how to obtain it, and how to upload it to your Holidu account.

Understanding the NRA and 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.

How do I obtain a Unique Registration Number (NRA)?

Follow this step-by-step process to obtain your NRA. You can also find detailed instructions in this video tutorial (in Spanish) for a visual walkthrough of the entire process.

Step 1: Prepare your documents

Before applying, gather the following documents:

  • Código Registral Único (CRU)
  • Cadastral Reference (or Boat ID if applicable)
  • Any local license or tourist authorization required by your region
  • Vacation rental license (licencia de alquiler vacacional)
  • "Declaración responsable" (if applicable)

Note: Please be advised that there may be a fee associated with obtaining the NRA number.

Step 2: Access the official registration platform

  1. Go to the Sede Electrónica del Colegio de Registradores

How to Check the Status of Your NRA

You can verify the current status and validity of your NRA at any time using the official verification portal managed by the College of Registrars:

Check your NRA status here

This tool allows you to confirm whether your NRA is provisional, permanent, or if there are any issues that need to be addressed.

What to Do if Your NRA Has Been Revoked

The Spanish government is actively enforcing compliance with the NRA requirement. We strongly recommend that you regularly check the status of your NRA using the verification link above.

If the status of your NRA shows as "revoked", please:

  1. Review the latest communication you should have received from the Sede de Registradores to understand the reason and required next steps
  2. If you have not received any communication, contact the Sede de Registradores directly for clarification
  3. Make sure the NRA configured in your Holidu account is correct and up to date

If your NRA has been revoked and is not resolved, your property may not be eligible for listing on rental platforms.

How to upload the NRA to your Holidu Account

Once you have obtained your NRA number, follow these steps to add it to your Holidu account:

Adding NRA during property setup or editing

  1. Log into your Holidu account
  2. Select the property that you want to update

  1. Submit the NRA for each property you operate

Adding NRA from the home screen banner (if property is already published)

If your property is already published and it is missing a valid NRA, you can add it directly from the home screen:

  1. In your Holidu Host Account, you'll see a banner at the top of the page

  1. Click on "Check the list" to open a page where you can enter the NRA for each of your properties

NRA Exemptions

If a property is legally exempt from having an NRA, the NRA field isn't mandatory to fill out. If the system detects that the property is not exempt from having an NRA, the NRA field will be marked in red with the label "Required field".

Rural Properties

At Holidu, we follow the interpretations published by the Spanish central government and the Autonomous Communities (CCAA) to determine whether an NRA number is required at the time of publication.

Examples of properties that currently do not require an NRA number:

  • Cantabria: Rural Houses (CR), Rural Inns (PR)
  • Catalonia: Rural establishments with licenses: PL, PCC, PT, PG, PTE, PB, and PVA
  • Balearic Islands: Agrotourism properties (AG), Inland tourism properties (TI)
  • Canary Islands: Emblematic Houses (A-35), Rural Houses (CR)

Please note that interpretations may change over time depending on agreements between the Autonomous Communities and the central government, so always verify the most recent guidance when in doubt.

Mandatory Requirements for Property Publishing

To ensure your property can be successfully published on Holidu, you must:

  • Obtain a valid NRA number from the Ventanilla Única Digital de Arrendamientos (unless your property qualifies for an exemption)
  • Upload the NRA to your Holidu account in the property's General Information section
  • Ensure the NRA is in the correct format (up to 53 alphanumeric characters)
  • Maintain an active and valid NRA status throughout the duration of your listing
  • Regularly check the status of your NRA to ensure it hasn't been revoked

Without a valid NRA, your property may not be eligible for listing or may be subject to removal from the Holidu platform.

Tips and Helpful Information

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

Yes. If you're an agency or property manager, you can apply on behalf of a property owner. 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.
