How to Safely Decide Whether to Return a Call from an Unknown Number

Receiving a missed call from an unknown number can be unsettling. While it's natural to want to identify the caller, returning such calls can expose you to various risks. Here's how to assess whether it's safe to call back:

Why Should You Be Cautious About Returning Calls from Unknown Numbers?

Scammers often use unfamiliar numbers to lure individuals into returning calls, leading to potential financial loss and personal information exposure. Engaging with these calls can confirm the validity of your number to scammers, increasing the likelihood of future unwanted contact. (techcrunch.com)

What Are the Common Risks Associated with Returning Unknown Calls?

  • Premium Rate Charges: Some numbers, especially those starting with area codes like 070, 084, 087, 090, 091, or 118, are associated with premium-rate services. Calling these can result in high per-minute charges. (ofcom.org.uk)

  • Scam Voicemails: Scammers may leave voicemails urging immediate callbacks, often leading to fraudulent schemes. (savisecurity.com)

  • Phishing Attempts: Engaging with unknown callers can expose you to phishing attempts, where scammers seek to steal personal information. (techcrunch.com)

How Can You Safely Determine the Nature of an Unknown Call?

  1. Check for a Voicemail: Legitimate callers typically leave a message. Review the voicemail for context before deciding to return the call.

  2. Use Reverse Phone Lookup Services: Websites like ZLookup or Whitepages can provide information about the number. Be cautious, as some services may charge fees or require personal information. (makeuseof.com)

  3. Consult Your Service Provider: Some carriers offer services to identify or block scam calls. For instance, T-Mobile's Scam Shield and AT&T's Call Protect provide such features. (reversephonelookup.org)

What Are the Best Practices to Protect Yourself from Unwanted Calls?

  • Avoid Returning Unknown Calls: If you don't recognize the number and there's no voicemail, it's safer not to call back.

  • Enable Call Blocking Features: Utilize built-in features on your smartphone or third-party apps to block spam calls.

  • Register with the National Do Not Call Registry: This can reduce the number of unsolicited calls you receive.
