How to Safely Return Calls from Unknown Numbers

Receiving calls from unknown numbers can be unsettling. Before returning such calls, it's crucial to assess their legitimacy to protect yourself from potential scams or unwanted solicitations. Here's how you can make an informed decision:

1. Why Did the Call Come from an Unknown Number?

Scammers often hide their caller ID to deceive individuals into answering. Legitimate organizations typically display their contact information. If the call is from an unknown number, exercise caution.

2. Did the Caller Leave a Voicemail?

Legitimate callers usually leave a message explaining the purpose of their call. If no voicemail was left, it might indicate a spam or robocall.

3. Can You Verify the Number?

Use reverse phone lookup services to check if the number is associated with known businesses or reported as spam. Websites like Phone-Spam.com allow users to report and search for suspicious numbers. (phone-spam.com)

4. Are There Red Flags in the Call?

Be wary of calls that pressure you to act immediately, request personal or financial information, or offer deals that seem too good to be true. These are common tactics used by scammers.

5. How Does Your Phone Handle Unknown Calls?

Many smartphones have built-in features to identify and block potential spam calls. For instance, iPhones with iOS 26 introduced the "Ask Reason for Calling" feature, which prompts unknown callers to state their name and purpose before the call connects. This helps screen out robocalls and deter scammers. (tomsguide.com)

6. What Are Your Options for Blocking Unwanted Calls?

Consider using call-blocking apps to enhance your phone's spam protection. Robokiller, for example, blocks 99% of spam calls and texts using advanced artificial intelligence. It offers features like customizable call blocking, audio fingerprinting to detect scammers, and spam text blocking. (robokiller.com)

7. How Can You Report Suspicious Calls?

Reporting spam calls helps authorities track and combat fraudulent activities. In the U.S., you can report unwanted calls to the Federal Trade Commission (FTC) through their website. (verizon.com)

8. What Are the Risks of Returning Unknown Calls?

Returning calls from unknown numbers can lead to unexpected charges, especially if the number is international or premium-rate. Additionally, some scammers use missed calls to prompt callbacks, which can result in high fees.

Conclusion

Before returning a call from an unknown number, assess the situation carefully. Utilize available tools and features to verify the caller's identity and protect yourself from potential scams.
