Do I need an ETA to visit the U.K.?

New electronic travel rules for visa‑exempt visitors to the U.K.

The U.K. now requires most visa‑exempt visitors to hold an electronic travel authorisation before they board a flight or ferry. The change was introduced as a digital border control measure; it affects travelers who previously could arrive with only a valid passport. Airlines have been instructed to check for the authorisation at point of departure and in some cases have denied boarding to passengers who do not hold one.

Who this affects

• Nationals from visa‑exempt countries, including U.S., Canadian and most European passport holders, are generally included. The new permission does not replace standard visas for travelers who already need one, but it is an additional requirement for the visa‑exempt.

Why it matters for planning

• Boarding denials are now a real risk if the authorisation is missing. That can leave passengers stranded and out of pocket for same‑day alternatives.
• The authorisation is separate from a visa and must be obtained in advance; it cannot be issued at the border.

What travelers should do

• Check the official U.K. government website for the eligibility list and the application process.
• Apply well before your departure date and confirm the authorisation reference number is recorded with your booking if the airline asks.
• Keep a copy of the confirmation and reconfirm with your carrier that they are accepting the document at check‑in.

Officials are enforcing the rule more strictly than in earlier transition phases, so securing the authorisation before you travel is now a basic part of trip preparation to the U.K.
