The 3-Day Registration Rule

In Portugal, all accommodation providers must register their guests with AIMA (formerly SEF) within 3 working days of arrival. This deadline is strictly enforced, and violations can result in significant penalties.

How to Count the 3 Days

The counting starts from the day after the guest arrives:

  • Day 0: Guest arrives (Saturday)
  • Day 1: First working day (Monday)
  • Day 2: Second working day (Tuesday)
  • Day 3: Third working day (Wednesday) - Deadline!

Note that weekends and public holidays are NOT counted as working days.

Example Scenarios

Scenario 1: Weekend Arrival

Guest arrives on Friday evening:

  • Friday: Arrival (Day 0)
  • Saturday/Sunday: Not counted
  • Monday: Day 1
  • Tuesday: Day 2
  • Wednesday: Day 3 (Deadline)

Scenario 2: Holiday Period

Guest arrives on Wednesday before a Thursday holiday:

  • Wednesday: Arrival (Day 0)
  • Thursday: Holiday (not counted)
  • Friday: Day 1
  • Saturday/Sunday: Not counted
  • Monday: Day 2
  • Tuesday: Day 3 (Deadline)

Penalties for Late Registration

Failing to meet the deadline can result in fines:

  • First offense: €500 - €1,000
  • Repeat offenses: Up to €3,500 per guest
  • Serious violations: Potential license suspension

What Counts as a Violation?

The following are considered violations:

  1. Not registering guests at all
  2. Registering after the deadline
  3. Providing incorrect information
  4. Failing to maintain records

Best Practices

To ensure you never miss a deadline:

  1. Register on arrival day - Don't wait until the last minute
  2. Use automated tools - Software like CheckinSimple can submit registrations automatically
  3. Keep a calendar - Track arrivals and ensure timely registration
  4. Have backup plans - Know how to submit manually if needed

Handling Special Cases

Some situations require extra attention:

  • Groups: Each guest must be registered individually
  • Children: Minors also need to be registered
  • Same-day departures: Still must be registered

Conclusion

The 3-day deadline may seem strict, but with proper organization and the right tools, compliance is straightforward. Automating your guest registration process is the most reliable way to avoid penalties and ensure peace of mind.
