Spam calls range from repeated marketing calls to scams designed to steal money or personal information. Some are easy to recognize; others imitate banks, delivery companies, technical support teams, or public institutions. A calm, consistent response can reduce the risk.
Common warning signs
- Unexpected requests for secrets: passwords, PINs, one-time codes, or full payment-card details.
- Pressure and threats: demands to act immediately, pay a fee, or keep the call secret.
- Unusual payment methods: requests for gift cards, cryptocurrency, or transfers to an unfamiliar account.
- Unclear identity: the caller refuses to explain which organization they represent or how to verify the request.
- Repeated unwanted calls: persistent calls after you have asked for them to stop may indicate unwanted marketing or harassment.
What to do during a suspicious call
- Do not confirm sensitive personal or financial information.
- Do not press keys or follow instructions simply because the caller tells you to.
- End the call if you feel pressured or uncertain.
- Contact the claimed organization independently using its official contact information.
How to report a spam number
Use your phone’s built-in reporting or blocking feature when available. You can also contact your mobile operator and follow the official consumer-protection or cybercrime reporting process in your country. Keep call times, messages, and other relevant evidence. Do not publish private information about a suspected caller.
If you use a community-based phone lookup service, read existing reports carefully and submit only accurate, relevant information. A report should describe the behaviour you experienced—not make unsupported accusations about a person.
Blocking and reporting are different
Blocking helps reduce calls reaching your own device. Reporting may share information with a provider or service to help assess patterns. One action does not necessarily perform the other, and neither guarantees that all future calls will stop.
Be aware of caller ID spoofing
Scammers can manipulate the number shown on caller ID. A familiar area code or a number that appears to belong to a real organization is not proof that the call is genuine. Always verify unexpected requests independently.
