National Registration (NRU) & EU Rules

Spain's NRU registration number, the annual February declaration and the EU short-term rental regulation that applies in full from 20 May 2026.

The national registration number (NRU): annulled

Royal Decree 1312/2024 created Spain's single digital rental registry (the Ventanilla Unica Digital de Arrendamientos). From 2 January 2025 hosts could apply for a national registration number (NRU) through the Land Registry, and from 1 July 2025 displaying it on every advert became mandatory; more than 215,000 applications were filed in the first six months. In May 2026 the Supreme Court annulled the registration procedure and the requirement to hold that number to offer a short-term let on a platform (judgments of 19 and 21 May 2026, published in the BOE in June 2026): the State does not have the competence to run a registry that overlaps the regional tourism registries. The numbers already issued no longer condition anything, and no new ones are needed.

The annual February declaration

The decree also required an annual informative declaration to the Land Registry every February (Article 10.4 of RD 1312/2024 and Order VAU/1560/2025); the first and only cycle ran in February 2026. Article 10 is among the provisions the Supreme Court annulled, so the filing no longer conditions your platform listings. Check the BOE before relying on any part of the decree.

The EU layer: Regulation (EU) 2024/1028

From 20 May 2026 the EU short-term rental regulation applies in full across the Union. Platforms such as Airbnb, Booking.com and Vrbo must share host and activity data with the authorities every month through the single digital entry point, which is the part of the Spanish decree that survived. Listings must carry the registration number that applies where the property is: in Andalucía that is the RTA code. Fines for non-compliance typically range from 10,000 to 60,000 euros depending on the region and the severity of the breach.

The Andalucian layer

In Andalucia the EU rules sit on top of Decreto 31/2024: registration in the Registro de Turismo de Andalucia (RTA), compliance with municipal planning rules and the minimum standards (at least 14 m² per guest place, enough bathrooms, ventilation and a way to darken bedroom and living-room windows, and cooling and heating for the months you let) remain mandatory, and the RTA code goes in every advert. Since March 2025, town halls can suspend new tourist-rental licences for up to three years in saturated zones, and since April 2025 communities of owners can authorise or veto new tourist flats by a three-fifths majority - see the community approval law page.
