Effective Strategies to Reduce Fraudulent Calls on Your U.S. Phone Number

Fraudulent calls, including robocalls and scam attempts, are a pervasive issue in the United States, disrupting daily life and posing significant risks. Implementing effective strategies can substantially reduce these unwanted interruptions.

What Are Fraudulent Calls and Why Are They a Problem?

Fraudulent calls encompass unsolicited telemarketing promotions, impersonation scams, and robocalls that you didn't request. Robocalls use automated dialers and recorded messages. Some automated calls are helpful, such as school notices or appointment reminders, but many are fraudulent or nuisances. (mcafee.com)

How Can I Block Unwanted Calls on My Cell Phone?

Utilize Built-in Features:

  • iPhone: Activate the "Silence Unknown Callers" feature by navigating to Settings > Phone > Silence Unknown Callers. This will send calls from numbers not in your contacts directly to voicemail. (techradar.com)

  • Android: Enable spam protection by going to the Phone app > Settings > Caller ID & Spam, and toggle on "Filter spam calls." (malwarebytes.com)

Carrier Services:

Major U.S. carriers offer services to combat fraudulent calls:

  • T-Mobile: Provides Scam Shield, which identifies and tags suspicious calls. (consumerreports.org)

  • Verizon: Offers Call Filter, which detects spam and blocks high-risk calls. (consumerreports.org)

What Are the Limitations of the National Do Not Call Registry?

How Can I Report Fraudulent Calls?

Reporting fraudulent calls helps authorities track and combat scams:

  • Federal Trade Commission (FTC): Report unwanted calls to the FTC at DoNotCall.gov. (usa.gov)

  • Your Phone Carrier: Many carriers have dedicated channels for reporting spam and scam calls.

Are There Additional Steps to Protect Myself from Fraudulent Calls?

Be Cautious with Personal Information:

Avoid sharing personal or financial information over the phone unless you're certain of the recipient's identity.

Educate Yourself on Common Scams:

Stay informed about prevalent scams to recognize and avoid them.

Regularly Review Call Logs and Voicemail:

Periodically check your call logs and voicemail for any missed calls or messages from unknown numbers.

By implementing these strategies, you can significantly reduce the number of fraudulent calls you receive, enhancing your privacy and peace of mind.
