As of July 1, 2025, a new regulation on short-term rentals comes into effect in Spain, aimed at increasing transparency and legality in the real estate sector. A key element of this regulation is the requirement for owners of short-term rental properties to obtain a Rental Registration Number (Número de Registro de Alquiler, NRA).

**What is a Lease Registration Number (NRA)?

NRA is a unique code assigned to each property offered for short-term rental. Its purpose is to ensure that the offer complies with current regulations and to facilitate monitoring of the rental market.

**Why is the NRA necessary?

Having an NRA is mandatory for all landlords planning to rent out their properties on a short-term basis. Without this number, it will not be possible to legally advertise or enter into rental agreements, which may result in legal sanctions.

**When is the NRA required?

NRA is essential in the case:

• Short-term rentals, whether tourist or non-tourist.
• Rental of entire properties or individual rooms.
• Properties already holding a travel license; NRA is an additional requirement.

**How to get an NRA

The process of obtaining an NRA includes the following steps:

1. Preparation of documentation: Gather documents proving the property's compliance with legal requirements, including:

• Tourist use license (if applicable).
• Energy certificate.
• Document confirming ownership of the property.

2. Online Registration: Go to the website of the College of Registrars (Colegio de Registradores) and log in with a digital certificate.

3. Fill in the form: Provide detailed information about the property, such as address, cadastral number, number of rooms, maximum number of guests, etc.

4. Application: Send the completed form with the attached documents. After verification of the data, a temporary NRA will be assigned, which will become a permanent number after successful evaluation.

Obligations of owners after obtaining NRA

Upon receipt of the NRA, owners are required to:

• Include the NRA number in all advertisements for rental properties on online platforms.
• Comply with local regulations for short-term rentals.
• Regularly update the property information in the registry.

Consequences of not registering

Failure to register and the NRA may result:

• Removing ads from rental platforms.
• Financial penalties.
• Legal problems associated with illegal rentals.

Summary

The introduction of the NRA is a step toward regulating the short-term rental market in Spain. For landlords, this means that they will have to comply with the new regulations, which will contribute to greater transparency and legality in the rental sector.
