Guest registration: SES, Mossos and Ertzaintza

Properties in Spain register their guests with SES.HOSPEDAJES, the national Ministry of Interior system — except in the two regions with their own police register: Cataluña reports to Mossos d'Esquadra and the Basque Country (País Vasco) to the Ertzaintza, instead of SES. Keyio detects your property's region automatically and shows only the credentials and submission options that apply to it — you don't need to figure out the right authority yourself.

You send guests a magic-link form (or they fill it in on check-in), they enter their details and scan their ID, and Keyio prepares the submission the way each authority actually expects it: sent directly for SES, as a downloadable TXT file for Mossos d'Esquadra, and as an XML file in the Ertzaintza's official format. You upload the Mossos file on their portal; for the Ertzaintza, Keyio sends the guest report and the booking for you once the establishment titular has authorised it (see “Sending to the Ertzaintza directly from Keyio”), and until then you upload the XML in the Registro Hostelero's “Envío fichero” tab. Before generating either file Keyio checks the data against that authority's rules and lists anything it would reject. Configure your SES credentials, Mossos police ID or Ertzaintza establishment code once per property from its compliance settings.

From a booking, send the guest self-registration link by email or WhatsApp to one or more of the booking's renters — you pick the recipients and the channel each time. WhatsApp delivery uses a Meta-approved WhatsApp Business Content Template sent via Twilio, so it only reaches renters with a phone on file; email needs no phone and is always available.

You can also have this link go out automatically ahead of check-in instead of sending it by hand each time — see "Auto-sending the registration link before check-in" below.

The report is due within 24 hours of arrival. From the day after check-in, a stay with no report filed appears in red under Action required, with a button to register the guests. It stays there for 14 days after the stay ends, or until the report is filed.

If you file reports outside Keyio, dismiss the alert for that stay, or mute the guest alerts of that property. Basque properties do not get this alert: they have their own Ertzaintza reminders.
