The Home Office have launched a 'beta' (working test) version of the 'EU Exit: ID Document Check' app for iPhone users. The new app is available for iPhone 7 and newer models as long as they have the most recent iOS software update.
The Home Office's Using the 'EU Exit: ID Document Check' app page provides information about using the Android and new iPhone apps, including the required phone specifications.
Applicants who are unable to use the Android or iPhone app because they do not have a biometric passport can either post their ID documents to the Home Office or attend one of their ‘ID Document Scanner Locations’ where they can have their passport scanned.
More information on the EU Settlement Scheme is found in our Brexit pages. If you wish to discuss your status or have questions about the EU Settlement Scheme, please contact either firstname.lastname@example.org or email@example.com in the Staff Immigration Team.
