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

Receiving calls from unknown numbers can be unsettling, especially when they bypass your call-blocking filters. To decide whether to return such calls, consider the following strategies:

1. Utilize Call-Blocking Apps to Screen Calls

Advanced call-blocking apps like Robokiller, Hiya, and Truecaller can help identify and block spam calls. Robokiller, for instance, uses predictive AI to block 99% of spam calls and texts, offering features like customizable block and allow lists, and answer bots that waste spammers' time.

2. Verify the Caller’s Identity

If a call from an unknown number gets through, use the app's caller ID feature to check if the number is associated with a known business or individual. Some apps provide reverse phone lookup services to help identify the caller. (callwave.com)

3. Assess the Nature of the Call

Consider the context of the call. If the number is from a local area code or matches a business you recently contacted, it may be legitimate. However, if the call is unsolicited and the caller is pressuring you for personal information or immediate action, it’s likely a scam.

4. Be Cautious with Personal Information

Never share sensitive personal information, such as Social Security numbers, bank account details, or passwords, over the phone unless you are certain of the caller's identity. Legitimate organizations will never ask for such information unsolicited.

5. Report Suspicious Calls

If you receive a call that you suspect is a scam, report it to your call-blocking app. This helps improve the app's database and protects other users from similar scams.

By implementing these strategies, you can make informed decisions about returning calls from unknown numbers and protect yourself from potential scams.
