Which Spam Blocker Should People Who Rely on Phone Calls Use on a US Phone Number Today

Spam calls are a pervasive nuisance for many phone users in the United States. In 2025, Americans received over 52.5 billion robocalls, averaging roughly 13–15 spam calls per person each month.

What Are the Risks of Spam Calls?

Spam calls can range from harmless telemarketing to malicious scams designed to steal personal information or money. In 2024, the Federal Trade Commission (FTC) received over 1.8 million do-not-call complaints, with the most reported scam types being impostor calls, warranty scams, and student loan fraud.
