If you run a tourist rental in Spain, SES.HOSPEDAJES is the platform you use to report your guests’ details to the Spanish Ministry of the Interior. The obligation is not new: it replaced the old paper guest report (parte de viajeros). What changed is that everything now runs through a single digital system governed by Royal Decree 933/2021.
This guide is the starting point: what it is, who must use it, how to log in, how to register, and what to do when something fails. Each section links to a detailed guide for the step you care about.
What SES.HOSPEDAJES is
SES.HOSPEDAJES is the Spanish Ministry of the Interior system through which accommodation establishments (and vehicle rental companies) report traveller and contract data. For a property manager, it is where the guest report lands: for every guest who stays, their identity data and the details of the stay must reach this platform.
The official portal is at hospedajes.ses.mir.es. It works in two ways:
- Manual web access: you log in to the portal, type each report’s data by hand, and submit it.
- Telematic submission (SOAP): your management software connects to the system with technical credentials and submits reports automatically, without you touching the portal.
The obligation is the same either way. The difference is how much time and how many errors it costs you to meet it.
Who must use SES.HOSPEDAJES
The obligation falls on whoever operates the accommodation, not whoever owns it. If you take in guests for a price, you report. That includes:
- Hotels, hostels, guest houses and hotel establishments in general.
- Viviendas de uso turístico (tourist-use dwellings) and tourist apartments.
- Rural houses, campsites and hostels.
- Anyone managing these properties on behalf of a third party (managers and agencies).
The 2026 Spanish Supreme Court ruling (STS 620/2026) changed which regional registries remain enforceable, but it did not eliminate guest reporting: the report to SES.HOSPEDAJES is still mandatory. We explain this in detail in tourist licence, NRUA and the guest report: what is still mandatory.
There are exceptions by age in the data to report (minors under fourteen are exempt), but the establishment is still obliged to report the rest of the stay.
How to access the official SES.HOSPEDAJES portal
Access to the Ministry portal (hospedajes.ses.mir.es) is by digital certificate. There is no “normal” username and password to log in to the web portal: authentication is always by certificate.
You need one of these:
- A FNMT certificate (individual or legal-entity representative).
- Cl@ve PIN.
- An electronic DNI with a reader.
The certificate must belong to the same person or entity registered as the holder of the accommodation. If the property is registered under a company and you log in with your personal certificate, the portal rejects access. This is the cause of most “it won’t let me in” cases.
Important: the web-portal access credentials (certificate) and the telematic-submission credentials (SOAP username and password) are different things, with different jobs. Mixing them up is the source of half of all failures. We separate them in the credentials guide.
If the portal won’t load, returns error 500, or rejects your certificate, work through the causes in SES.HOSPEDAJES not working.
How to register with SES.HOSPEDAJES
Before submitting a single report you need three things:
- A lessor code (código de arrendador): identifies the person or company operating the accommodation.
- An establishment code (código de establecimiento) for each property you operate.
- Technical credentials (SOAP username and password) if you are going to submit via software.
Registering as a lessor and registering each establishment are done in the portal with your digital certificate, and the system assigns the codes when you finish. The full process, with requirements, screens, the detail of each credential and the typical registration errors, is in the dedicated guide: SES.HOSPEDAJES credentials: lessor code and SOAP.
Have ready, before you start: a valid digital certificate, NIF or CIF, the tourist registration number of each property, the full postal address, the accommodation type and the declared capacity. Having it on hand keeps you from abandoning the form halfway.
How to submit a guest report to SES.HOSPEDAJES step by step
Once registered, the flow for each report is this:
- Collect the guest’s data. Full name, document type and number, date of birth, nationality and the other fields required by Royal Decree 933/2021. Incomplete data is the number-one cause of silent rejections.
- Tie the report to an establishment. Each report is linked to the establishment code of the specific property where the guest is staying.
- Submit within the deadline. The report must reach SES.HOSPEDAJES within the 24 hours following the start of the stay.
- Check the response. The system validates at two moments: an immediate format rejection and, sometimes, a silent data rejection hours later. Confirm the report was accepted, not just “submitted”.
- Keep the record. The data is retained for the legal period and must be available if requested.
If a submission is rejected with a numeric code, the error-codes guide decodes them one by one. And if you need to cancel or correct a report already submitted, it has its own procedure.
Deadlines and required data
The two numbers you cannot forget:
- 24 hours from the start of the stay to report.
- Three years of data retention, with automatic deletion afterwards.
The detail of which fields are mandatory, the legal basis on which the data is processed, and what happens if you don’t report is in the Royal Decree 933/2021 guide. The penalties for non-compliance range from €100 for a minor breach up to €30,000 for serious ones, reaching €600,000 in the most serious cases (LO 4/2015).
When SES.HOSPEDAJES fails
Almost every problem falls into one of three categories, and it pays to tell them apart because the fix differs:
- The portal doesn’t respond (won’t load, error 500, won’t accept the certificate): usually a service incident, an expired certificate, or the browser. Covered in SES.HOSPEDAJES not working.
- A report is rejected with a code (10103, 10107, 10121…): a credentials or data problem. Decoded in the error-codes guide.
- You submitted something wrong and need to undo it: you have to cancel or correct the report and resubmit the right one.
The distinction that saves the most time: a portal failure and a report rejection are not the same thing. They aren’t fixed in the same place.
Automating submission to SES.HOSPEDAJES
Complying by hand is possible, but it means logging in to the portal for every guest, typing their data without a single error, and watching the 24-hour clock. For a manager with several properties, it is a constant source of rejections and wasted time.
The alternative is to automate the flow end to end: the guest enters their own data in an online check-in, the system validates it before sending, and the report reaches SES.HOSPEDAJES on time without anyone copying anything by hand. That is exactly what RegistroViajero does: you configure the credentials once and every validated booking is reported on its own.
We don’t issue licences and we don’t replace the Ministry’s portal. We handle the part that costs you the most errors and time: the correct, on-time submission.
Frequently asked questions
What is SES.HOSPEDAJES? It is the Spanish Ministry of the Interior system through which tourist accommodations report their guests’ data (the guest report, parte de viajeros) in compliance with Royal Decree 933/2021. The official portal is at hospedajes.ses.mir.es.
How do I access SES.HOSPEDAJES? You enter the web portal with a digital certificate (FNMT, Cl@ve PIN or electronic DNI) belonging to the person or entity that holds the accommodation. There is no conventional username and password for web access; the certificate is the authentication mechanism.
Is SES.HOSPEDAJES mandatory after the Supreme Court ruling? Yes. The 2026 ruling affected certain regional registries, but it did not eliminate guest reporting. The report to SES.HOSPEDAJES is still mandatory for tourist accommodations.
How long do I have to submit the guest report? The report must reach SES.HOSPEDAJES within the 24 hours following the start of the guest’s stay.
Why can I log in to the portal but my software can’t submit reports? Because web access (by certificate) and telematic submission (by SOAP username and password) use different credentials. Check that your software has the correct service-web credentials and that the password hasn’t changed in the portal.
Do I need an establishment code for each property? Yes. The lessor code is unique per holder, but each property you operate has its own establishment code, all linked to the same lessor.
