The Federal Communications Commission (FCC) knows that robocalls have gotten worse in recent years, and it's finally doing something about it. In June 2019, the FCC voted to give phone carriers the freedom to block spam calls without waiting for customers to opt in. The change is a good first step, but it won't end the robocall scourge completely. For the unwanted calls that sneak past your phone's defenses, the FCC also published a scam glossary on its website, Popular Science reports.

The glossary lists some of the most common (as well as some uncommon) strategies used by criminals, giving you an idea of what to be on the lookout for next time you get a suspicious call. The "Health Insurance Scam," for example, involves callers selling fake health care coverage for a cheap price. There's also the "One Ring Scam," where the scammer will hang up quickly after the first ring without giving you time to answer the call. Their goal is to trick you into calling them back and paying for international call fees.

The glossary includes more general terms that relate to phone scams as well. Spoofing is defined as calls made through fake caller IDs that appear trustworthy, either by matching your home area code or that of a legitimate organization. Slamming happens when a phone company moves you from your existing service provider to theirs without your consent.

Familiarizing yourself with popular scams is one of the easiest ways to protect yourself from falling for fraudulent calls. Another way is to install robocall-blocking apps on your phone. Here are some options to check out.
