Reporting the guest report by hand (copying the ID, filling in fields, uploading them one by one to SES.Hospedajes) is one of the tasks that steals the most time and is easiest to forget. And every report left unsent is a potential infraction under Royal Decree 933/2021.
A traveler registration app exists precisely so that this process stops depending on you: the guest identifies themselves from their phone before arriving and the report travels to the Ministry of the Interior’s platform on its own. In this article you’ll see exactly what an app like this does, how it works step by step, what legal obligation it covers, and how to tell a good one from one that will cause you problems.
What a traveler registration app is
It’s software that automates the two obligations every tourist accommodation in Spain has: identifying each guest and reporting their data to the authorities. Instead of doing it by hand at the front desk, the app sends the traveler an online check-in link where they type their document details, complete the remaining fields, and sign the entry report. The app translates that information into the format SES.Hospedajes requires and transmits it for you.
It’s not the same as a simple web form. A traveler registration app is connected to the official system, validates the mandatory fields, and keeps proof of every submission. It’s the difference between “collecting data” and “complying with the law in a demonstrable way”.
Why automate: the problem with the manual process
Manual registration seems cheap until you add up what it really costs:
- Time: each report is several minutes of typing and uploading. Multiply it by every guest, every week.
- Errors: a mistyped document number or a wrong issue date can invalidate the submission. What each rejection message means and how to fix it is in SES.Hospedajes errors.
- Forgetting: the day you have three back-to-back check-ins is the day a report goes unsent.
- Deadlines: the submission has specific windows; doing it by hand makes it easy to be late.
- No trail: if an authority asks for proof, “I think I sent it” doesn’t count as evidence.
Automating eliminates all four sources of risk at once: the data is entered by the guest themselves (fewer errors), the submission is immediate and logged (no forgetting or missed deadlines), and it’s archived (a demonstrable trail).
How it works, step by step
The flow of a traveler registration app is always similar, regardless of the size of the accommodation:
- Confirmed booking. When a booking comes in (direct or from an OTA), the app prepares a personalized registration link for that stay.
- Invitation to the guest. That link is sent by email or WhatsApp, ideally alongside the booking confirmation email, so the traveler can complete it at their leisure before traveling.
- Identification from the phone. The guest types their document type and number (DNI, NIE, or passport) and the remaining mandatory fields, which the app validates as they go. They do not have to photograph or upload the document: the AEPD holds that asking for a copy breaches the data minimisation principle.
- Digital signature. The traveler signs the entry report electronically.
- Automatic submission to SES.Hospedajes. The app transforms the data into the official format and reports it for you, within the deadline, saving the receipt.
- Storage that expires. Reports are kept for the period the regulation requires, three years, and deleted automatically when it runs out.
The result for you: on arrival day there’s no paperwork at the door and the legal obligation is already met without you typing a single field.
What legal obligation it covers
The reference rule is Royal Decree 933/2021, which regulates the documentary registration and reporting of lodging data through SES.Hospedajes (the Ministry of the Interior’s platform that channels what used to be done with the National Police or the Civil Guard depending on the area). It affects the entire hospitality sector: hotels, hostels, guesthouses, and vacation rentals (whether you call it VUT, VFT, HUT, ETV, or whatever applies in your region).
If you want the detail on who is required, what data is requested, and how to fill in the report, you’ll find it developed in our guide to traveler registration and SES.Hospedajes. An app doesn’t exempt you from knowing the rule: it complies for you, but the responsibility still lies with the accommodation owner.
What a good traveler registration app should have
Not all solutions are alike. Before choosing, compare what really matters against continuing to do it by hand:
| What to check | Manual process | Traveler registration app |
|---|---|---|
| Connection with SES.Hospedajes | Field-by-field upload | Automatic submission within deadline |
| Data entry | You type the document | The guest types it from their phone |
| Risk of error | High | Low (field validation) |
| Receipt for each report | Manual, easy to lose | Archived automatically |
| Report signature | On paper | Digital signature |
| Integration with your software | None | PMS, channel manager, and OTAs |
| Demonstrable compliance | Hard to prove | Full traceability |
Beyond the table, pay attention to three things that make the difference: that document reading works well with foreign IDs and passports, that storage meets the retention period the rule requires, and that you have support in your language when the official platform throws an error (something that happens more than it seems).
Integrations: PMS, channel manager, and OTAs
The value of an app grows when it stops being an island. If your solution connects with your PMS and your channel manager, the bookings coming in through Airbnb, Booking, or other OTAs trigger the registration link on their own, without you having to create anything by hand. That way the flow is continuous: the booking comes in, the invitation goes out, the report arrives. That synchronization is what turns registration into something that happens in the background instead of one more task on your list.
Security and data protection
You’re handling identity document data, which is sensitive personal data. The first rule is not to collect more than you need: the AEPD holds that asking for a copy of a DNI or passport in order to comply with RD 933/2021 breaches the data minimisation principle, because the document carries fields the report never asks for and keeping that image creates a risk you did not have to run. A serious app collects only the required fields, keeps them for the legally required period (and no longer), and deletes them when it expires. Check that the provider complies with the GDPR and signs a data processing agreement with you; we go into it in the post on guest data protection. Collecting documents without proper handling doesn’t solve a legal problem: it creates another.
How much time (and money) it saves
The underlying argument is simple: manual registration is repetitive work that adds nothing to the guest experience and a lot of risk. Automating it frees up hours every week, reduces questions and waits at arrival, and, above all, cuts the probability of a penalty for an unreported report. In a sector where one infraction can cost far more than years of software subscription, the math is usually clear. And if you operate without a license or have doubts about your situation, before automating it’s worth resolving the basics: check whether your rental could be considered an illegal vacation rental.
Frequently asked questions
Is it mandatory to use an app for traveler registration? No. The obligation is to report to SES.Hospedajes; you can do it manually. The app is not a legal requirement, it’s the way to meet that obligation without errors or forgetting and leaving a trail of every submission.
Does the app submit the report automatically to SES.Hospedajes? Yes. It collects the guest’s data, translates it into the official format, and reports it for you within the deadline, saving the receipt. You don’t type or upload anything manually.
Does it work for vacation rentals as well as hotels? Yes. RD 933/2021 applies to all lodging: hotels, hostels, guesthouses, and tourist-use dwellings. A good app adapts to both a single property and several.
What happens if SES.Hospedajes fails on a check-in day? With the manual process you’re stuck. An app handles the resubmissions and notifies you of the status of each submission, on top of offering you support to resolve the incident.
Does digital registration comply with data protection? It must. Require data minimisation (it should not ask you for a copy of the ID, as the AEPD warns), retention for the legal period only, and GDPR compliance. If a tool collects documents without those guarantees, it’s creating a risk, not eliminating one.
