Robocall

A robocall uses an autodialer and pre-recorded audio to contact many phone numbers simultaneously. While legitimate uses exist (appointment reminders, emergency alerts), fraudulent robocalls are one of the most prevalent forms of telephone-based scam. Common scripts impersonate government agencies (HMRC, IRS, Social Security Administration), banks, utility companies, tech-support services, and delivery couriers.

The messages typically create urgency — 'your National Insurance number has been suspended', 'press 1 to speak to an agent about your compromised account' — to provoke an emotional response that leads the victim to engage with a live fraudster. Victims who press a number or call back are transferred to scam call centres where trained agents extract money or personal data.

Autodialing technology makes robocall campaigns extremely cheap: millions of calls can be made for a few hundred dollars using voice-over-IP infrastructure, and caller ID spoofing makes each call appear to come from a local or official number. Regulatory agencies continually battle robocall operations, but international jurisdiction gaps allow many to operate freely.
