With Holidu, you can automatically collect your guests' information and submit it directly to the SIBA portal (Sistema de Informação de Boletins de Alojamento), helping you meet legal requirements in a simple, practical, and secure way.

Note: Holidu facilitates the collection and transfer of guest data, but legal compliance remains the responsibility of the host. For further legal information, please consult the official SIBA portal.

Before You Start - What are the prerequisites?

Before activating the guest registration feature with Holidu, please make sure that you have the following in place:

  2. Your SIBA credentials available:

    • Authentication Key (usually a 12-digit password)
  3. The credentials should match those used to access the official SIBA Portal
  4. The bulletin submission method in the SIBA portal is set to "SEF-SIBA web service integration". If another method is currently active, you must contact SIBA directly to request a change: https://siba.ssi.gov.pt/contactos

What happens after the activation

After activating the SIBA connection, your future bookings will automatically be associated with a secure check-in form. This applies to bookings with a check-in date at least 6 days after the configuration is completed.

The form is automatically sent to guests by email or via message through your booking channel.

Example of the automated form being sent to guests via email notification

Guest's point of view

After booking, guests receive a form link via email or through their booking platform message (such as Airbnb). They must fill out the details for all guests, including children. Guests can complete this manually or by scanning their ID documents.

Data Security and Reminders

The data is securely stored. If guests don't fill out the form, automatic reminders will be sent 5 days prior to the check-in date. If the form remains incomplete by check-in day, the host must collect the information manually using the same link.

After 11:00 PM on the check-in date, the data is automatically sent to the SIBA portal.

Frequently Asked Questions

When do the guests receive the form?

Guests receive the form link immediately after booking via email. If the form remains incomplete 5 days before arrival, an automatic reminder is sent.

What about multi-unit properties?

The feature is not yet available for properties with multiple units (such as properties with separate rented rooms). Holidu is working to make this available soon.

What happens to bookings made before activating SIBA with Holidu, but with future check-ins?

The form will only be sent automatically if SIBA configuration was completed at least 6 days before check-in. If not, the host must manually submit guest data to SIBA.

Do I need to register all guests, including minors?

Yes, all guests must be registered. Minors can be registered by their parents or legal guardians.

What if guests don't fill out the form?

Guests will receive an automatic reminder 5 days before the check-in day. If the form remains incomplete, the host can fill it out during check-in or resend the link to ensure it's completed before 11:00 PM on the check-in day.

Can I edit the form after submission?

No. Once submitted to SIBA, the data cannot be changed. For corrections, contact the SIBA portal directly: https://siba.ssi.gov.pt/

Will I receive a notification when a guest completes the form?

No. You will need to check the booking details manually to verify completion.

Can I use this configuration for all bookings?

Only bookings made via connected channels on Holidu are supported. Manual bookings or iCal imports are not supported.

What if a guest fills in their data and then cancels?

The data will not be sent to SIBA. Transfers only occur for active reservations on the check-in day.

Do secondary accounts have access to this feature?

No. Only the main account holder can configure the feature. Collaborators can see the form in the reservation details but cannot manage or activate it.
