If you’re an Alojamento Local manager in Portugal, ensuring the legality of your business is a top priority. One of the most significant legal obligations is registering with the SEF’s (Foreigners and Borders Service) SIBA system. In this article, we’ll guide you through the SIBA registration process, a vital step in managing local accommodations. Additionally, we’ll introduce you to our new tool, UpMarket’s SEFScan, designed to streamline your local accommodation management.

Step-by-Step Guide to Registering on SEF’s SIBA

  • Visit
  • Fill out the form with the requested information. Mandatory fields are marked with an asterisk (*).
  • SIBA registration is legally required for all entities operating a local accommodation. Initially, you’ll need to identify the NIF (Tax Identification Number) of the entity managing the accommodation, which may or may not differ from the property owner.
  • After identifying the NIF for SIBA registration, select the CAE – Economic Activity Code that fits your business. Under “Tipologia/Classificação”, consider the modality under which you registered your local accommodation and choose the corresponding option.
  • Use the same “Nome da Unidade” you entered when registering your local accommodation with Turismo de Portugal. In the following field, indicate the Entity Manager’s name corresponding to the NIF identified at the beginning of the registration.
  • For the local accommodation address, first enter the postal code, followed by the door number, floor, and any additional information, if applicable. Although “Fax” is marked as mandatory (*), it doesn’t need to be filled out, as the registration can be successfully submitted without this field.
  • In the “Envio de boletins por (*)”, select “Web Service” to allow electronic transmission of Accommodation Bulletins through SEFScan.
  • Click “Enviar” to complete your registration.
  • After submission, you’ll receive an official email from SEF within 1 to 3 business days, confirming your registration and providing access credentials for communication with SEF.
