Spain's Royal Decree 933/2021 requires accommodation providers to register guests and report stay details to the authorities. If you host guests in Spain, this applies to you. This guide explains what the decree requires, how Holidu's online check-in feature helps you comply, and the steps to set it up.

What is Real Decreto 933/2021?

Real Decreto 933/2021 is a Spanish law designed to improve security and help prevent criminal activity in the holiday rental and vehicle rental sectors. Under this decree, hosts and intermediary platforms such as Holidu must collect and report detailed information about guests, properties, and bookings to the Spanish Ministry of the Interior.

You can read the full text in the official BOE publication of Royal Decree 933/2021.

How does this affect Hosts?

If you have a property in Spain listed on Holidu, you must report guest and booking details within the legal deadline after each check-in. This applies no matter where you live or what your nationality is.

You are responsible for collecting the following information:

• Host details
• Property details
• Guest information for every guest in the booking, including:
  • Full names
  • Date of birth
  • Residency address
  • Contact details (phone or email)
  • ID type and number (for adults)
  • "Soporte" ID number for guests with a Spanish ID (NIF or NIE)
  • Relationship to any minors, when applicable
• Booking and transaction details (Holidu collects these automatically)

Where do you report this data?

You report guest data to the SES Hospedajes platform, run by the Spanish Ministry of the Interior. If your property is in Catalonia, continue reporting to the Mossos d'Esquadra. If it is in the Basque Country, report to the Ertzaintza.

How does Holidu help you comply?

Holidu makes compliance easier through its online check-in feature. Here is how it works:

• Holidu collects and securely stores the booking and property data it needs.
• Guests complete their mandatory details through an online check-in form. Holidu emails this form, and it is also accessible in the booking details.
• Once you have set up the feature, Holidu automatically sends the guest details to your chosen authority by 11:00 PM on the check-in day.
• If a booking is later cancelled, Holidu updates SES Hospedajes to withdraw the reported information.

Even with automatic reporting, you remain responsible for making sure all mandatory details are complete and accurate.

How to submit guest data through Holidu: step-by-step

Follow these steps to set up online check-in and submit guest data through Holidu:

1. Register on the SES Hospedajes platform through the official Ministry of the Interior website.
2. Select "Hospedajes y alquiler de vehículos" and find the "Access to the register of HOSPEDAJES establishments and entities."
3. During registration, select "Send communications via webservice."
4. In your Holidu account, activate the Guest Online Check-in feature and choose your relevant authority: SES Hospedajes, Mossos d'Esquadra, or Ertzaintza.

Checklist: am I set up correctly?

• You have selected the correct authority in your Holidu account.
• You have entered the correct login credentials.
• You have checked "Send communications via webservice" on SES Hospedajes.
• You check that guest details are complete before check-in. If anything is missing, collect it from guests directly at check-in.

When did the decree take effect, and what are the penalties?

The decree came into force on January 2, 2023, with a transition period until October 1, 2024. After that date, incomplete information (serious) or late information (minor) may result in fines:

• Minor: €100 to €600
• Serious: €601 to €30,000
• Very serious: €30,001 to €200,000

The rules for reporting are also set out in BOE-A-2015-3442, Article 39.
