As of February 21, 2025, travelers to the United Kingdom are now required to obtain an Electronic Travel Authorization (ETA). This new requirement applies to Americans and other nationalities, with applications having opened in November for travel starting in the new year.
The application process is described as straightforward but includes a few key steps. According to the U.K. government website, the easiest way to apply is through the official government app available on iOS and Android devices. Applicants are advised to use only the gov.uk website or the official app to avoid unnecessary fees. The ETA costs 10 British pounds, approximately $13.
If access to the app is not possible, applications can be completed online. However, using the app involves verifying an email with a six-digit code before proceeding with photographing and scanning one's passport. "That was the trickiest part," said Lyndsey Matthews, who encountered challenges during her application process. She advised removing any phone cases when scanning passports.
