The useful question is which prescribed check applies to this person and whether your team completed it. “Digital” describes a delivery method, not a guarantee of a stronger statutory excuse.
Distinguish three different processes
The employer guide explains the Home Office online service, manual document checks and eligible digital right-to-work verification providers. The online service gives a Home Office result for an eligible person. A digital provider has a defined scope. A scan sent by email is neither of those processes merely because it is electronic.
British and Irish citizens can use eligible document routes, including a manual route where appropriate. Do not demand an immigration share code from someone who cannot obtain one. Check the current provider requirements and what remains for the employer to do.
Complete the manual route properly
Manual checks require the specified original documents and the employer's required checks. A live video call can be used for the identity comparison where the employer has the originals in physical possession. This is different from examining only emailed photographs during a call.
An expired British or Irish passport can be acceptable for a manual check under the relevant list. Other documents and digital-provider eligibility have different conditions. Check the particular route instead of applying one “in-date only” rule to everything.
Retain the result and decision
For an online check, use the employer service and retain its result; a worker's own status screenshot is not the employer check. Confirm the photograph and any limits on the actual job. For another route, retain the evidence prescribed for that process with the check date.
Keep unresolved identity or permission questions open until they are reviewed. Neither optical character recognition nor a generic identity match establishes a statutory excuse by itself.
Certifyd helps organise check evidence and review dates. It does not replace the online service, an eligible verification provider or the employer's prescribed manual actions.
