From today, the conditions for traveling are becoming easier. Thanks to the change to code yellow, recorded at the last Codeco, it is no longer necessary, from March 11, to fill in the Passenger Locator Form (PLF). This form was previously to be completed by travelers (vaccinated and unvaccinated) transiting through airports, ports and international stations, and who had spent more than 48 hours in a foreign country, whether a member of the European Union or not.
Now, all that changes. If you are returning to Belgium following a stay in a European country or a country that appears on the white list of the European Union (which you can find here), no need to fill in the PLF. You will therefore only have to complete it if you are returning from a trip to a non-EU Member State that is not on this list.
