SES Hospedajes: what it is, how to register and comply in 2026

What is SES Hospedajes?

SES Hospedajes is the digital platform of the Spanish Ministry of the Interior through which accommodation establishments report guest data to the authorities.

It is part of the SES system (Sistema de Entrada de Viajeros) and replaces older reporting systems such as Webpol and Hospederías. It became fully operational at the end of 2024.

The goal is to centralise and digitise traveller registration, which until now was handled with paper forms or scattered systems.

How to register step by step: arrendador, establishment and Cl@ve

Before you can file any report you have to register in the system. Registration rests on two roles that are easy to confuse: the arrendador — the company or individual holding the accommodation activity, the party under the obligation and the one answerable to the authorities — and the establishment, each specific physical property where travellers are hosted. One arrendador can have one or many establishments.

The process is done at the electronic office and requires an electronic ID method: an FNMT digital certificate (personal or company-representative), an electronic DNI, or Cl@ve. Without one of them you cannot even reach the registration form.

The digital certificate is the most common route, especially when the activity is run by a company. It has to be valid and properly installed in the browser you log in from: an expired certificate — or one installed in a different browser — is the most frequent reason the office will not let you in. Cl@ve is the alternative if you would rather not manage a certificate, with a requirement of its own: having registered with Cl@ve beforehand.

When you register the holder, the system links it to an arrendador code that identifies it as the party under the obligation and that travels in the header of every filing: it is how SES Hospedajes knows who is submitting the report. Each property you then register gets its own establishment code, which identifies that specific property in every report, and generates its own reporting credentials: a username and password specific to the filing service.

Those reporting credentials are not the same as the certificate or Cl@ve you use to enter the office, and mixing them up is the most common stumble on a first filing. The 401 error almost never comes from the certificate but from an invisible whitespace character copied in when pasting the username or password: re-enter them with no leading or trailing spaces. If needed they can be regenerated at the office itself, bearing in mind that the previous ones stop working and have to be updated in every connected system that uses them.

The structure is layered: one arrendador (the obligated party) → several establishments (each property) → each establishment with its own code and reporting credentials. It is the model designed for anyone running several properties, because you do not need a separate account per property. And if you manage flats belonging to several owners and each of them holds their own activity, each owner is a separate arrendador in the system, with their own establishments: for every property it is worth being clear about which holder the reports are filed on behalf of, because the arrendador is the one legally answerable for them.

Once registered, the recurring obligation begins: file every stay within 24 hours of the guest’s arrival and keep the lote code the system returns when it accepts the submission, which is the proof that it was filed on time. The registration path, in order, is always this:

• ✓Get your electronic ID method ready: a digital certificate, the electronic DNI, or Cl@ve, with the prior Cl@ve registration done if you take that route.
• ✓Register the arrendador, the holder of the accommodation activity: it receives the arrendador code and is legally answerable for the filings.
• ✓Register each establishment under that same arrendador; each property gets its own establishment code.
• ✓Save each establishment’s reporting credentials — the filing-service username and password — copied with no leading or trailing spaces.
• ✓To grow, add new establishments to the same arrendador: there is no need to redo the holder’s registration each time.

How to comply with SES Hospedajes effortlessly

Doing this filing manually, guest by guest, consumes hours and invites errors. BookCheckin automates the whole process end to end.

The guest completes online check-in before arrival: they scan their document, review their data, and sign. BookCheckin validates the information and files it with SES Hospedajes within the legal deadline, and keeps the receipt.
