How to Block Fake Local Calls: A Comparison of Robokiller and Nomorobo

Receiving calls from numbers that appear local can be frustrating, especially when they are spam or scam calls. This tactic, known as "neighbor spoofing," is commonly used by scammers to increase the likelihood of you answering the call. To combat this, call-blocking apps like Robokiller and Nomorobo have been developed. In this article, we'll compare these two services to help you determine the best solution for blocking fake local calls.

What Is Neighbor Spoofing and Why Is It a Problem?

Neighbor spoofing occurs when scammers manipulate caller ID information to display a number similar to yours, often within the same area code and prefix. This technique exploits the tendency of individuals to trust and answer calls from local numbers, making it more challenging to identify and block unwanted calls. (support.robokiller.com)

Robokiller offers a feature called "Neighbor Spoof Blocking," which automatically blocks numbers that resemble your own, typically those with the same first 5–6 digits. This significantly reduces spoofed calls. Additionally, you can manually block specific number patterns for even more control. (support.robokiller.com)
