You can do an online check using the online service – https://www.gov.uk/view-right-to-work.
The online right to work checking service sets out the information you require to complete the check. In some circumstances, it will not be possible to conduct an online check (i.e. British, settled persons); in these cases, you should conduct the manual check or use a Home Office-approved identity service provider.
Individuals must first provide a share code to the employer to conduct the online check. The individual will generate a 9-character share code to pass to the employer. The employer should then enter the share code and the individual’s date of birth to access the online check.
The employer must then check that the photograph on the online check is the individual presenting themselves for work. This can either be in person, or by video call.
The employer must retain evidence of the online right to work check. This should include the ‘profile’ page confirming the individual’s right to work, showing the photo, and date the check was conducted.
You must carry out an online video call to satisfy yourself that the person is who they say they are. You do not need to see the physical documents as the right to work information is provided directly from the Home Office systems at the time the check is conducted.
