What SES.Hospedajes is

SES.Hospedajes (Sistema de Entrada de Viajeros, RD 933/2021) is the state system that requires registering the details of every guest aged 14 or over staying at your property, with reporting within 24 hours of their arrival. The data is kept for 3 years.

It doesn't apply only to short-term rentals: hotels, guesthouses, and other types of accommodation are also required to comply. For a short-term rental host, it's one of the recurring obligations that's easiest to overlook — it's not a one-time procedure like regional registration, but something you repeat with every stay.

Find out in 7 questions whether your rental is compliant or what it's missing. You'll get a clear diagnosis and the solutions to get in order:

The two regional exceptions

Not all of Spain uses SES.Hospedajes:

Catalonia: the system is run by the Mossos d'Esquadra, not SES.Hospedajes.
Basque Country: the system is run by the Ertzaintza, not SES.Hospedajes.

If your property is in either of these two regions, the procedure and the deadline may differ from the rest of Spain — use the test to confirm the exact system for your region.

Why it's a recurring infraction

Unlike not having your tourist registration (which is a continuous but single violation for as long as it lasts), failing to register a guest with SES.Hospedajes is something that happens again with every stay. That means a host with frequent bookings and no automated process can rack up several violations in a short time, even without realizing it.

Manual vs. automated

Doing it by hand satisfies the obligation, but carries a higher risk of delays or human error that can lead to penalties — especially if you manage several properties or check-ins outside normal hours. Automating registration with an online check-in tool reduces that risk because it captures guest data and submits it to the corresponding system without relying on you to remember every time.

What to do now

Confirm which system applies in your region (SES.Hospedajes, Mossos d'Esquadra, or Ertzaintza).
If you're doing it manually, consider automating it — especially if you manage several properties.
If your situation with guest registration in SES.Hospedajes isn't clear, it's better to raise it proactively than to find out through a notice.

Frequently asked questions

What is SES.Hospedajes?+

The state system (RD 933/2021) for registering the details of every guest aged 14 or over, with mandatory reporting within 24 hours of their arrival. The data is kept for 3 years.

Does SES.Hospedajes apply across all of Spain?+

Not exactly. In Catalonia the system is run by the Mossos d'Esquadra and in the Basque Country by the Ertzaintza, not SES.Hospedajes. The rest of the regions use the state system.

What happens if I don't register my guests in time?+

It's a recurring infraction, not a one-off: each guest who isn't registered, or registered late, can count as a separate violation, which increases the risk much faster than a single infraction would.

Can I automate this registration?+

Yes. Online check-in tools exist that automate capturing guest data and submitting it to SES.Hospedajes (or the corresponding regional system), reducing the risk of forgetting or delays.
