15. Before we decide if we should conduct a detailed investigation of a complaint, we look at whether there are signs the organisation has got something wrong. We do this by comparing what should have happened with what did happen.
16. A passport applicant must nominate someone they know to confirm their identity. The person nominated is known as a ‘referee’ or ‘counter-signatory’. For online passport applications, the applicant can nominate either a digital (online) referee or a paper referee. HMPO’s website explains the criteria to be a referee.
17. Once the customer nominates their referee online, HMPO’s Digital Customer Services (DCS) sends an email asking the referee to verify the applicant’s identity. To do this, the referee must provide the application reference number and the intended passport holder’s date of birth.
18. DCS conducts automatic checks as the referee completes the application and verifies the customer’s identity. If any of the automatic checks are unsuccessful then DCS will reject the digital referee.
19. There are two main reasons why DCS would automatically reject a referee. Either the referee:
• fails the initial security checks because the details entered do not match the details held by HMPO, or • gives unacceptable answers to the qualifying questions.
20. HMPO guidance was updated in July 2025. However, the relevant parts remained the same as those used at the time of the events Mr X has complained about. For this reason, we have relied on them as appropriate standards.
21. The guidance says if any of the automatic checks are unsuccessful then DCS will reject the digital referee. HMPO will tell the customer and digital referee they have been rejected but it will not tell them why.
22. In this case, HMPO rejected Mr X as a digital referee and notified him and his friend. This suggests Mr X did not pass one or more of the automatic checks. We have not been able to establish which checks were unsuccessful, as HMPO does not store this information.
23. Our role is to consider whether an organisation has followed the relevant guidance. We can see HMPO acted in line with its own guidance when it did not to give Mr X further detail about the rejection.
24. We understand why Mr X wanted to know the specific reason for the rejection. Unfortunately, this is not possible, but we understand why the lack of explanation caused him worry and uncertainty about his suitability to act as a referee.
25. We have seen no indication of failing in this complaint and will not be continuing our consideration. We thank him for bringing his concerns to us.
