This is indeed from Teleperformance, working for NHS Bloodline. It is a reliable number; however, due to remote calling by vetted individuals, returning their calls may not always be feasible. If it appears as HM Passport in a search, it’s simply the Slough exchange, not a scam or bogus call.

Expert Opinion
Recent spikes in reports highlight a pattern of callers pretending to be the HM Passport Office. Many victims describe brief, scripted greetings, requests for security questions, or sudden hang‑ups, which are classic social engineering tactics. The number also shows up in unrelated scams – student loans, NHS blood services, and even bogus insurance offers – indicating it’s likely a hub for impersonation attacks rather than a legitimate service line. To stay safe, never share personal or financial details unless you’ve independently verified the number on an official website, use call‑blocking tools, and report suspicious calls to the relevant fraud authority. A quick callback to the official passport helpline can confirm authenticity.

Survey
The caller introduced themselves as being from Visit Britain, adopting a somewhat forceful tone by stating they would be asking questions, rather than requesting permission to do so

Silent Call
The caller didnt respond when I answered the phone
Just had a call from someone claiming to be from NHS blood donation. They addressed me by name, asked for my year of birth, and then discussed booking a blood donation appointment. I made the appointment, and immediately received an email confirmation from the official NHS Blood service. I also checked my NHSBlood app, and the appointment was confirmed. Everything seems legitimate.
The caller pretended to be from the Student Loans Company, requesting that I complete a 'security' procedure over the phone
The caller claimed to be representing the Student Loans Company, which requires further verification to determine the legitimacy of the call.
