3. Perform a Reverse Phone Lookup

4. Trust Your Instincts

If the call seems suspicious or the caller is pressuring you for personal information, it's best to err on the side of caution and avoid returning the call.

By combining these strategies, you can make informed decisions about whether to return calls from unknown numbers, thereby protecting yourself from potential scams and unwanted solicitations.
