Since the final entry into force of the Real Decreto 933/2021, guest registration in Spain has ceased to be a simple “paper and signature” formality to become a comprehensive digital process, resolving the bureaucracy of your accommodation with our Traveler Registration App. It is no longer enough to note the ID; now, the regulation demands an unprecedented amount of data and almost instant communication with the Ministry of the Interior.
If you are looking for a technological solution, these are the non-negotiable features your app must have to ensure your business is 100% protected against fines of up to €30,000.
Native Connection with SES.HOSPEDAJES
Starting from December 2024, the SES.HOSPEDAJES platform of the Ministry of the Interior became the sole and mandatory channel for most of the national territory (replacing or centralizing the former submissions to the Guardia Civil Lodgings and WebPol). With Registro Parte Viajeros you have a Traveler Registration App with all the necessary functionalities to comply with legal obligations.
The key: Your app must be integrated via API with SES.HOSPEDAJES. If the application forces you to download a .txt file to upload it manually, you are not automating, you are just changing writing tools.
Capture of the “New Data” from RD 933/2021
The new law requires collecting up to 17 data fields per traveler, many of which do not appear on the chip or on the front of a traditional ID card. An efficient app should allow you to easily capture:
- Contact details: Mobile phone number and email address (mandatory).
- Relationship: Mandatory when there are children under 14 years old.
- Transaction data: Payment method (card, cash, transfer), cardholder, and card expiration date.
Intelligent OCR Scanner
To avoid human errors — which are grounds for sanctions — the app must have OCR (Optical Character Recognition) technology.
- Scan the MRZ code: The app must read the machine-readable zone of passports and DNIs in seconds.
Legal Digital Signature (eIDAS Compliance)
The entry form must be signed by all travelers over 14 years old. The app must allow touchscreen signature and generate a PDF document (the “Entry Form”) that complies with the legal standards of electronic signature, unequivocally linking the signature with the registration data.
Secure Storage for 3 Years
Spanish law requires establishments to keep the documentary record for a period of 3 years starting from the end of the stay.
- Security: Look for apps that use bank-grade encryption (AES-256) and strictly comply with the RGPD.
- Accessibility: In case of an inspection, you must be able to retrieve and download any part of the input from the last 36 months immediately.
Deadline Automation (24-Hour Rule)
Communication to the authorities must be made within a maximum period of 24 hours from the start of the service (check-in) and, in some cases, even from the confirmation of the reservation.
- Automatic sending: The app should send the data at the moment the registration is completed, without manual intervention, and return a successful sending receipt.
| Requirement | Manual / Paper Registration | Travelers Part Registration |
| Time per guest | 5-10 minutes | Less than 1 minute |
| Data error | High (illegibility) | Very low (OCR reading) |
| Shipping to Mainland | Manual (risk of forgetting) | Automatic and instant |
| 3-year warranty | Physical file cabinets (take up space) | Secure and organized cloud |
| Compliance RD 933/2021 | Very difficult to manage | Integrated by default |
In 2026, operating a vacation rental or hotel without an automation tool is not only inefficient, it is a financial risk. A good check-in app is not an expense, it is a legal insurance that allows you to focus on the most important thing: your guests enjoying their stay.
