SES Hospedajes in Spain: How to Automate Guest Registration for Your Vacation Rental

Last updated: March 2026

If you rent out a property in Spain, guest registration is not optional. Every host is legally required to collect specific traveller data and report it to the Ministry of the Interior through a national system called SES Hospedajes. It replaced the old paper-and-fax "parte de viajeros" with a single electronic platform — and it expects the data quickly, in a structured format, for every guest who stays with you.

The good news: what used to be a tedious manual chore can be almost entirely automated. This guide explains what SES Hospedajes is, exactly what you have to report, the deadlines and penalties to be aware of, and how an online check-in can generate the required file for you — so compliance happens in the background instead of eating your evenings.

What SES Hospedajes is

SES Hospedajes is Spain's national guest-registration system, run by the Ministry of the Interior (Ministerio del Interior). It centralises the reporting obligation that used to fall on hotels, campsites, tourist apartments and short-term rentals under separate, paper-based procedures. Instead of handing a stack of forms to the local police, hosts now transmit traveller data electronically to a single government platform.

The obligation applies to anyone providing lodging for payment, including private vacation-rental owners and property managers. The system also extends to companies that rent vehicles, but for our purposes what matters is the lodging duty: for every stay, you must identify who is staying, collect a defined set of personal and contract data, and communicate it within the legal window. It is the modern, digital version of the parte de viajeros — the traveller report Spanish hosts have filed for decades.

What traveller data you must report

SES Hospedajes asks for two kinds of information: data about each guest, and data about the stay itself (the "contract"). While the exact fields evolve, the reporting broadly covers:

• Guest identity. Full name and surnames, identity or passport document type and number, nationality, date of birth, and (for adults) contact details such as a phone number or email.
• Every traveller, not just the lead booker. Registration typically covers all adult guests staying at the property, so a family or group booking means several records, not one.
• Stay and payment data. Check-in and check-out dates, the property or establishment reference, the number of travellers, and details relating to how the stay was contracted and paid.

Because this is personal data collected under a legal obligation, it must be handled in line with data-protection rules — kept secure, used only for the required purpose, and not retained longer than the law permits.

Deadlines for submitting the parte de viajeros

The core rule is simple: reporting is required within a short legal deadline after the guest checks in. In practice that means you cannot leave registrations to pile up and submit them at the end of the month — each stay has to be communicated promptly once the guest arrives (and, in some cases, the contract data earlier still).

Deadlines and their exact wording have changed as the system rolled out, so always verify the current requirement on the official Ministry of the Interior channels. The practical takeaway does not change: the safest approach is to capture guest data before or at arrival and submit it the same day, rather than scrambling to reconstruct it afterwards. Automating the capture step is what makes hitting the deadline effortless.

Penalties for non-compliance

Failing to register guests — or doing it late, incompletely, or inaccurately — is treated as a breach of citizen-security obligations and can carry administrative fines. Penalties can be significant, and the exact euro amounts depend on the nature and seriousness of the breach, so verify current figures before you rely on any number you read online.

Beyond the fine itself, non-compliance creates a paper trail that can complicate a tourist-licence renewal or an inspection. For a professional host, the reputational and operational cost of being flagged as non-compliant usually dwarfs the effort of simply doing it right. The obligation is not going away, and enforcement is easier now that everything is digital — which is all the more reason to make registration automatic.

How to streamline the whole process

Doing this by hand — photographing IDs at the door, typing each guest into a government portal, cross-checking fields — is slow and error-prone, especially with back-to-back stays. The way to stay compliant without the busywork is to collect the data once, cleanly, and let software format and file it. A good process looks like this:

• Ask guests to complete an online check-in before arrival, from their own phone, entering their details and document data directly.
• Validate as you go so missing or malformed fields are caught before the deadline, not after.
• Generate the required electronic file automatically in the exact structure SES Hospedajes expects, ready to submit.
• Keep a record of what was collected and sent, so you have proof if you're ever asked.

This turns a compliance headache into a two-minute step the guest does for you — while also giving you a smoother, more professional arrival experience.

How Zobooq generates the required XML

Zobooq's online check-in is built exactly for this. When a guest books, they're invited to complete a digital check-in from any device: they enter their personal and document details, and each additional traveller is registered too. Zobooq validates the fields as they're entered, so you don't discover a missing passport number the night before the deadline.

From that data, Zobooq automatically generates the structured XML file in the format SES Hospedajes requires — and can submit it electronically on your behalf, so the parte de viajeros is filed without you touching a government portal. Your traveller data is captured once, formatted correctly, and reported on time, for every stay. What used to be a nightly chore becomes something you barely notice.

With Zobooq, online check-in and Spanish guest registration are part of the same all-in-one platform that also gives you a direct-booking website, a booking engine, and secure payments. €29.95/month on the Pro plan, with zero commissions on every direct booking you win.
