To identify whose number is calling you, you can use several methods:
- Use a reverse phone lookup service or app like Truecaller, Sync.ME, or Whitepages, where you enter the phone number and get caller details such as name, location, and spam reports if available.
- Dial * 69 (on most carriers) to automatically call back the last private or unknown number that called you, which can reveal the number, though it may not work if the caller used advanced masking.
- Contact your phone service provider to see if they offer anonymous or spam call identification and blocking tools, such as AT&T Call Protect, Verizon Call Filter, or T-Mobile Scam Shield.
- Use trusted websites like whocallsme.com or tellows.com where users report spam or suspicious numbers; entering a number there might reveal whether the number is associated with spam or scam.
Be cautious about answering unknown callers or texting them back, as these might be automated spam or scam calls. Blocking unwanted numbers and reporting suspicious calls to authorities is also recommended.
In summary, the fastest way is to use apps like Truecaller or do a reverse phone lookup online to identify unknown callers by their number.
