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

SES Hospedajes is the Spanish Ministry of the Interior platform through which tourist accommodations report their guests’ data. Here is what it is, who it affects, and how to comply effortlessly.

Royal Decree 933/2021 explained

RD 933/2021 governs the registration and reporting of guest and customer data in Spain. Here is who it affects, what obligations it imposes, and how to comply.

The libro registro de viajeros: from the paper book to the computerised register

Royal Decree 933/2021 changed how guests are registered in Spain: the libro-registro (the register book) described by Orden INT/1922/2003 gave way to a computerised register and a telematic report within 24 hours. Here is what still stands, what does not, and what to do today.

The traveller report: what it is and how to file it

The traveller report (parte de viajeros) is the mandatory reporting of your guests’ data to the authorities. Here is what it is, how it has changed, and how to do it in minutes.

Traveller report or booking report: which one you have to send

SES Hospedajes has two distinct communication types, and the most repeated doubt is which of the two applies. We compare them field by field, with the text of Royal Decree 933/2021 and the Ministry of the Interior’s technical specification in front of us.

Accessing SES Hospedajes: which credential is which and where to find it

SES Hospedajes does not hand you one credential but several, and most access problems come from using one where another was needed. This guide separates them, says where each one lives inside the Ministry of the Interior’s portal and which screen you have to open to see it.

Alloggiati Web: reporting guests to the Questura in Italy

Alloggiati Web is the Polizia di Stato portal through which accommodation providers in Italy report to the Questura (the provincial police headquarters) the details of the people staying with them. This is an informational guide: once you switch Alloggiati Web filing on for your property, BookCheckin transmits each completed check-in for you, signing in with the credentials your Questura issued you.
