Complying with Royal Decree 933/2021 and the citizen security regulations is not just “filling out a paper”. It is a legal process which, if done incorrectly, can result in penalties of up to €30,000.
At registroparteviajeros.com we see hundreds of records daily and have detected the most common mistakes hosts make. Here we tell you about them so you don’t fall into them.

Do not register ALL guests
It is the number one error par excellence. Many owners think that registering the “holder” of the reservation is enough.
- The reality: The law requires the registration of all persons over 14 years old staying in the property.
- Consequence: An incomplete record is considered a serious violation. If there are 4 adults, there must be 4 entry parts.
Confusing the “Issue Date” with the “Expiration Date”
It seems obvious, but with the rush of in-person check-in and the poor lighting in some lobbies, it is very common to mix up these dates.
- The problem: The authorities’ systems (such as SES.HOSPEDAJE) may reject the submission if they detect inconsistencies in the document dates.
- Tip: Pay close attention to the labels on the ID or passport. If you use an automatic scanning system, make sure the camera focuses correctly.
Delay in data transmission (The 24-hour deadline)
The registration does not end when the guest signs the report; it ends when that information reaches the authorities.
- The rule: You have a maximum period of 24 hours from the start of the stay to communicate the data.
- The mistake: Waiting until the end of the weekend to send all the reports together. This creates a digital non-compliance trail that is easily detectable during an inspection.

Do not keep the signed reports
Even if you send the data electronically, the obligation of custody does not disappear.
- The obligation: You must keep the entry reports (the “register book”) for a period of 3 years, arranged chronologically.
- The mistake: Deleting the photos of the IDs or throwing away the papers once uploaded to the platform. In case of a physical inspection, they will ask you for the printed or digital record book duly paginated.

Errors in the “Document Type”
A Spanish DNI is not the same as a NIE, a passport, or an identity card from an EU country.
- The common mistake: Marking all records as “DNI” by default. Each type of document has a specific code in the data submission. If the code does not match the document number format, the system will return a validation error.

Conclusion: Technology is your best ally
