Guest Check-In for Short-Term Rentals in Portugal: How to Do It Legally and Automatically

Guest check-in for a short-term rental is more than just handing over the keys.

It’s a critical moment where you must:

  • Collect guest information

  • Comply with legal requirements

  • Deliver a smooth first experience

If handled manually, this process can quickly become slow, inefficient, and error-prone.

What Should Happen During Check-In?

During check-in, you are expected to:

  • Verify guest identity

  • Collect required personal details

  • Confirm reservation details

👉 This information is not optional — it is legally required.

Connection to SIBA (Guest Reporting)

The data collected during check-in is the same data that must be reported through SIBA (guest registration system).

This includes:

  • Full name

  • Date of birth

  • Nationality

  • ID/passport number

  • Stay dates

👉 If this data is incorrect or incomplete, your SIBA submission will also be incorrect.

Common Problems With Manual Check-In

Many hosts still rely on manual processes, which often lead to:

  • Missing or incomplete data

  • Typing errors

  • Delays in submitting to SIBA

  • Duplicate or inconsistent records

These issues can result in:

  • Compliance risks

  • Fines

  • Extra administrative work

Guest Experience Matters

Check-in is also your guest’s first real interaction with your property.

A slow or disorganized process can lead to:

  • Frustration

  • Negative first impressions

  • Poor reviews

👉 A smooth check-in sets the tone for the entire stay.

Manual vs Digital Check-In


Manual check-in:

  • Paper forms or verbal data collection

  • Data entered later into systems

  • Higher risk of mistakes


Digital check-in:

  • Guests fill in details before arrival

  • Data is structured and stored automatically

  • Ready for compliance reporting

👉 This approach saves time and reduces errors.
