UK eVisa system reportedly links twin sister's immigration status to wrong identity
↗
A legally settled UK resident was temporarily barred from boarding a flight after the Home Office’s eVisa system incorrectly associated her status with her twin sister’s details.
This incident exposes a critical flaw in the UK’s digitised immigration system, where identity mismatches can strand individuals abroad. For engineers, it underscores the risks of deploying large-scale digital identity systems without robust fail-safes or manual overrides. The reliance on automated verification without adequate error correction mechanisms creates operational and reputational risks for both users and the system itself.

The eVisa system incorrectly linked a woman’s settled status to her twin sister’s identity, preventing her from boarding a flight.
The Home Office acknowledged the issue as a 'known problem' affecting some twins and claimed it had since been resolved.
Similar cases have raised concerns about the system’s reliability, with critics warning of a rushed rollout and lack of stable proof mechanisms.
