The tourist accommodation sector in Spain is in full transformation to adapt to the new national and European legal requirements. Among acronyms, rules and records, it is easy to get lost: What is the SES? What is the NRA for? What changes with the Digital Single Window (VUD)?

In this article we explain it in a simple and updated way so that you know exactly what you must do to comply with the law and avoid sanctions.

✅ 1️⃣ What is the SES?

SES it means Interior Ministry Lodging System. It is the official platform where all accommodations — from hotels to tourist apartments and rent a car — are required to Communicate to the Police or Civil Guard the data of all its guests and drivers.

This is regulated by Royal Decree 933/2021, which states that traveler information should be sent in a maximum of 24 hours from your arrival or from the formalization of the reservation or rental contract.
