GOV.UK ID Check is an identity verification app developed by the UK Government Digital Service to provide users with a secure and convenient way to confirm their identity when logging into government services using GOV.UK One Login. The app ensures the authenticity of the user's identity by matching the user's facial features with the image on their photo ID.

To use GOV.UK ID Check, users need to have one of the following types of photo ID: a UK light card driving license, a UK passport, a non-UK passport with a biometric chip, a UK Biometric Residence Permit (BRP), a UK Biometric Residence Card (BRC), or a UK Border Worker Permit (FWP). It is worth noting that even if the BRP, BRC or FWP has expired, users can still use them for identity verification within 18 months of their expiration.

During the use of the app, users need to perform different actions depending on the type of photo ID they have. If the user's ID is a UK driving license, they only need to take a photo of the driver's license and scan their face with their phone. If the user's ID is a passport, BRP, BRC or FWP, they also need to scan the biometric chip in the ID with their phone. Once these steps are completed, the app will automatically match the user's facial features with the image on the ID document to confirm the user's identity.

The GOV.UK ID Check app takes user privacy and security very seriously. Your personal information is not stored while using the app, but is securely deleted after use. In addition, the app uses advanced encryption technology to protect the security of your data.

Overall, GOV.UK ID Check is a powerful, secure and reliable identity verification app that provides users with a simple and quick way to confirm their identity when using government services. With this app, users can access government services more conveniently while ensuring the security and privacy of their personal information.
