In Catalonia and the Basque Country, traveller data goes to a regional system of its own, not to SES Hospedajes. Here is how it works.
SES Hospedajes is national, but there are regional systems
SES Hospedajes, run by the Ministry of the Interior, is the general traveller-reporting system in Spain. But two autonomous communities have their own police force with competences in this area.
In Catalonia and the Basque Country, accommodations report their guests’ data to the regional police’s own system instead of to SES Hospedajes. It is not an extra layer — it is a different recipient.
Catalonia: the Mossos d’Esquadra
In Catalonia, the competent force is the Policia de la Generalitat - Mossos d’Esquadra. Accommodations located in Catalan territory must take their traveller-data reporting system into account.
For the accommodation, what matters is that its reports reach the right recipient depending on where the property is.

The Basque Country: the Ertzaintza
In the Basque Country, competence lies with the Ertzaintza. As in Catalonia, accommodation establishments located there must channel their guests’ information to the corresponding regional system.

The challenge: reporting to the right system
The most common mistake is reporting to the wrong system. Filing a Bilbao or Girona property’s data with SES Hospedajes does not make you compliant — that report must go to the corresponding regional system.
Each property has a single recipient, and it depends on where it is. The efficient approach is to collect the guest’s data once — with the document scanned and a digital signature — and to be clear about which system each report must go to.
Where BookCheckin fits here (and where it does not)
BookCheckin automates filing to the national SES Hospedajes, the recipient in every community without its own police registry. Catalonia is covered too, by a different route: on the property’s Legal tab you enter, once, the establishment id the Mossos d’Esquadra issued you when your establishment registered at registreviatgers.mossos.gencat.cat, and confirm it. Until it is on file, that property cannot create check-in links; once it is, check-in works exactly as it does everywhere else in Spain —the guest fills in their data, scans their document and signs— and BookCheckin generates the file for your guests in the official V24 format, which you download and upload yourself to the Mossos portal.
That last part is literal: the submission on their portal is yours to make. We get the file ready; we do not send anything to the Mossos and we hold no credentials of theirs. In the Basque Country, with the establishment code the Ertzaintza issued you added and switched on for the property, BookCheckin prepares the file in the XML format of the Ertzaintza’s Registro Hostelero and you upload it in their portal. BookCheckin never signs in to the Ertzaintza portal, never sends anything on your behalf and holds no credential for it. The Ertzaintza’s Registro Hostelero is the most recent route we have opened. If their portal rejects a file, tell us from the contact page — or from Support inside your dashboard — with the error message, and we will fix it.
