Online Check-in - How to Connect to SIBA

Portugal's local authorities require accommodation providers to register guest information through the SIBA portal (Sistema de Informação de Boletins de Alojamento). Holidu simplifies this process by automatically collecting guest data and submitting it to SIBA on your behalf. This guide walks you through connecting your property to SIBA via Holidu and managing guest registrations efficiently.

Important Note: Holidu helps with collecting and transferring guest data, but legal compliance remains your responsibility. For full legal information, consult the official SIBA portal at https://siba.ssi.gov.pt.

1. Before You Start - What Are the Prerequisites?

Before activating the guest registration feature with Holidu, ensure you have the following in place:

  • A property already registered on the official SIBA portal: https://siba.ssi.gov.pt
  • Your SIBA credentials readily available:
    • NIF (VAT number) of the Hotel Unit
    • Establishment Code
    • Authentication Key (typically a 12-digit password)
  • Confirmation that your submission method in the SIBA portal is set to "SEF-SIBA web service integration"

If your submission method is set to another option, follow these steps to change it:

  1. Log in to your SEF account at https://siba.ssi.gov.pt/s/an/default.aspx
  2. Change the submission method to Web Service
  3. Update the field "Automatically send info to" to "SEF-SIBA web service integration"

If you cannot make this change yourself, contact SIBA directly to request assistance: https://siba.ssi.gov.pt/contactos

Frequently Asked Questions

What about multi-unit properties?

This feature is currently not available for properties with multiple units (such as properties with separate rented rooms or apartments). Holidu is working to extend this functionality to multi-unit accommodations in the future. Please contact support for updates on your specific property type.

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 the check-in date. For bookings made before this window, you must manually submit guest data to SIBA through the official portal.

Do I need to register all guests, including minors?

Yes, all guests must be registered, including minors and children. Minors can be registered by their parents or legal guardians using the online form or manually at check-in.
