Why do unknown numbers call you?
Not every unknown call is malicious. Sometimes it is a delivery driver, a doctor's office, or a friend with a new number. However, in 2026 phone scams have increased by 40% globally.
Common reasons for unknown calls:
- Telemarketing — companies selling products or services
- Phone scams — fraudsters impersonating banks, tech support, or government
- Ping calls (Wangiri) — one-ring scams designed to make you call back premium numbers
- Wrong number — someone dialed incorrectly
- Legitimate business — delivery, medical, or service providers
