Yes — since 1 July 2025 every short-term rental advertised on an online platform in Spain has needed a national registration number (número de registro único) issued through the Property Registry, and the platform must display it on the listing and refuse bookings without it. It applies to tourist lets, seasonal lets and rooms alike, it sits on top of the regional tourist licence your community already requires, and it has to be kept current with an information return every twelve months.
The detail
The rule comes from Royal Decree 1312/2024, Spain's implementation of the EU short-term rental regulation (2024/1028), which took effect on 1 July 2025 and which the EU regulation itself made mandatory across every member state from 20 May 2026. The owner applies to the Registro de la Propiedad for the property, declaring the type of let and confirming that the relevant regional and municipal permissions are in place; the registrar issues the number, which is then entered on the national digital window (Ventanilla Única Digital de Arrendamientos) that platforms report into. Airbnb, Booking.com and Vrbo now require the number at listing stage.
The registrar is not a rubber stamp. Registrars have suspended applications where the building's community statutes prohibit tourist use, and a number can be revoked when the registrar's checks find the declaration defective or unsupported — the revocation goes to the digital window and the platforms must take the listing down. That links three systems that used to be separate: the regional tourist licence (the VUT in Madrid, HUT in Catalonia, VFT in Andalucía), the community of owners' rules, and the platform's own verification.
What it does not do is grant permission. A registration number is proof that you have declared the let and that the paperwork behind it exists; the right to operate still comes from the region and the municipality, and those are where the restrictions are — Barcelona's licence phase-out by November 2028, Madrid's limits on tourist flats in the centre, Málaga's three-year freeze on new tourist-let licences across the whole city from August 2025, and the growing number of communities of owners voting to prohibit tourist use under the 2025 reform of the horizontal property law.
The numbers that matter
Where this stops holding
Fees, processing times and how strictly registrars test community statutes vary by registry and are still settling, and the regional licence regimes underneath the national number differ in every autonomous community. The number needs a return every twelve months, so a change in the building's rules or a regional tightening can end an operation at the next one. Nothing here is Spanish legal advice for a specific property; a local gestor or lawyer is a small cost against a revoked listing.
