What is the HUTB number?

Barcelona short-term rentals must carry a HUTB number (format HUTB-NNNNNN) issued by the Generalitat de Catalunya under Decret 75/2020. The Catalan government plans to revoke all Barcelona-municipality HUTB licences by November 2028 to free up long-term housing supply.

Catalunya uses the HUTB registry (Habitatge d'Ús Turístic — Barcelona) under Decret 75/2020. The format is HUTB-NNNNNN with a six-digit serial. Catalunya stopped issuing new HUTB numbers inside Barcelona's L'Eixample-Sants-Sant Martí perimeter in 2014 and the moratorium was extended again in 2024.

From November 2028 the Generalitat plans to revoke all existing HUTB licences within Barcelona municipal limits — about 10,000 listings — to free up long-term housing supply. Operators are already required to display the HUTB number on every listing under Decret 75/2020; ~39% of scraped Barcelona listings carry no number at all today.

The new EU central register (Real Decreto 1312/2024, 20 May 2026 deadline) layers on top of the regional HUTB. Listings without an EU NRUA reference will be pulled by Airbnb and Booking from that date.

Common questions

How does the EU NRUA differ from my regional VT/HUTB?

Your regional number (VT- in Madrid, HUTB- in Catalunya, etc.) is issued by your CCAA. The EU NRUA, created by Real Decreto 1312/2024 and EU Regulation 2024/1028, is a central Spanish register that feeds into the EU system. From 1 July 2025 every listing has to display an NRUA reference; from 20 May 2026 Airbnb and Booking must verify it against the central register before publishing the listing. Existing regional registrations feed into the central NRUA automatically.

What happens if my listing doesn't have a number?

Regional fines for unregistered VUT operations have ranged from €5,000 to €100,000 since 2022 (varies by CCAA). On top of that, from 20 May 2026 the platforms are themselves required to pull listings without a verified NRUA reference under EU Regulation 2024/1028. The platform action doesn't replace the regional exposure — both apply.

Can my listing show 'Exempt' for the registration field?

Some Spanish listings legitimately qualify for the vivienda-habitual exemption (under 90 days/year of non-resident rental). If you've correctly declared exemption with your CCAA, 'Exempt' is fine. The platforms still verify the declaration against the central register; an unsubstantiated 'Exempt' value gets the same treatment as a missing one.

Where does this data come from?
