If you are renting out a property in Spain, whether in bustling Barcelona or peaceful rural areas, it’s important to understand the new rule about displaying your New Tourist Accommodation Registration Number Spain on all rental advertisements. Since July 1, 2025, Spanish law mandates that all short-term rental properties must prominently feature their Rental Registration Number (NRA) in every listing and promotional material. This requirement is more than just bureaucratic red tape—it plays a critical role in ensuring your rental business operates legally and successfully.

What Exactly Is the Rental Registration Number?

The Rental Registration Number, known in Spanish as Número de Registro de Alquiler (NRA), is a unique identifier issued by the government when a property is registered under the Single Tourist Rental Registry. This registry centralizes all short-term rental properties to regulate the sector, improve safety, and promote fair competition among property owners.

Each NRA is linked directly to a specific property and rental license type. It serves as proof that the property complies with all local and national tourism laws, including safety, quality standards, and tax obligations.

Why Must the NRA Be Displayed?

The legislation requires rental owners to clearly show their NRA on:

All online rental platforms (e.g., Airbnb, Booking.com, Vrbo)
Social media advertisements
Personal rental websites
Printed materials or signage used to promote the property

Failure to display the NRA can lead to your listing being removed from online platforms and potential fines from regulatory authorities.

Benefits of Displaying Your NRA

1. Legal Compliance
Displaying the NRA is legally mandatory and helps avoid costly penalties or forced delisting from popular rental platforms.

2. Increased Trust from Guests
Travelers are increasingly savvy about booking properties with proper registration. Seeing the NRA reassures potential guests that the rental meets government standards, which can lead to higher booking rates.

3. Enhanced Transparency
By showing the NRA, owners contribute to a transparent rental market where authorities can monitor the sector effectively and ensure fair competition.

4. Protection Against Fraud
Scams and unlicensed rentals are common in popular destinations. Registered rentals are easier for guests to verify, providing an added layer of security.

How to Properly Display the NRA

Include the NRA prominently in the property description on all booking platforms.
Add the number to your rental contract and confirmation emails.
If you have a physical rental office or signs, print the NRA clearly.
Avoid abbreviations or partial numbers—always use the full code as provided.

Common Mistakes to Avoid

Not updating existing listings: Simply registering for the NRA isn’t enough; owners must update all listings with the correct number.
Using outdated NRAs: If you change ownership or update your registration, make sure to update the number across all platforms immediately.
Ignoring local requirements: Some regions require the NRA alongside other local licenses or certificates—make sure you’re fully compliant.

Consequences of Not Displaying Your NRA

Spain’s authorities, working with rental platforms, are cracking down on non-compliant listings. The consequences include:

Removal of your listing from major booking sites.
Fines that vary by region but can be substantial.
Possible legal action for repeated offenses.
Negative impacts on your ability to rent in the future.

What About Rentals Not Covered by the NRA?

Some types of rentals, such as long-term leases or certain exempt properties, may not require an NRA. However, if you rent out a property for stays shorter than the minimum period defined by your regional laws, the NRA is almost always mandatory.

Summary

For any property owner offering short-term rentals in Spain, the Rental Registration Number is no longer optional—it's a legal requirement that must be clearly displayed on every listing and advertisement. Beyond legal compliance, displaying the NRA helps build trust with guests and ensures your rental business runs smoothly without interruptions.
