Europeans travelling to the UK will be required from 2 April to obtain prior authorization, which will cost 12 euros and can be requested digitally from today.
The Electronic Travel Authorization (ETA) is already required for visa-exempt visitors from outside the European Union.
Similar to ESTA in the United States, ETA aims to strengthen border security, according to British officials.
From 10am today, citizens of around thirty European countries - including all those in the European Union (EU), with the exception of Ireland - can begin the process of obtaining this authorization.
The request can be made via the 'UK ETA' app or via the British government website, in a process that should take just a few minutes, according to the British Home Office.
The cost will currently be £10 (€12), but the government hopes to increase the amount to £16 at an as-yet unspecified date.
The ETA allows stays of up to six months, as well as unlimited travel for two years, but the application must be renewed in the event of a passport change.
The system was launched in 2023 to "secure borders" by "digitizing the immigration system."
"ETA's expansion across the world confirms our commitment to strengthening security through technology and innovation," said Secretary of Migration and Citizenship Seema Malhotra.
From 2 April, all travelers will need an ETA or visa to travel to the UK which left the European Union in 2020.
