Crowdsourced labels help, but they are not evidence. What actually tells you whether a call is risky.
What the labels mean
Apps show labels like "spam", "bank", "delivery" or a company name. They come from other users, from business directories and from automated analysis of call patterns. A label is a hint, not a fact.
Objective data you can check
- Operator and range — a number can belong to a company rather than a person.
- Line type: mobile, landline or toll-free (8-800).
- Whether the number is published on the organisation's official site.
Signs of a fraudulent call
- Urgency: money is being stolen right now, act immediately.
- A request for a code, password or card details — never legitimate.
- An offer to "cancel a transfer" or "protect your account".
- A request to install an app or share your screen.
What to do
Hang up and call the organisation back using the number from its official site. If the call was genuine, nothing is lost. If it was not, you avoided the scheme entirely.
Reporting
Report the number to your operator and to the app you use. Reports feed the databases everyone else relies on.
