The Estonia Passenger Locator is essentially a brand new international travel document which all travelers to this Baltic state needs to fill out before coming in Estonia. This document was made to have greater control over non-authorised entry to the country should any medical emergency occur. Additionally, it aims to keep track of all expatriates, their possessions and any other assets which they could have in the country. All of this will make life extremely hard for an individual needing to enter the country illegally.
