Effective Strategies to Reduce Fraudulent Calls on Your US Phone Number

Receiving fraudulent calls on your US phone number can be both disruptive and potentially harmful. Implementing effective strategies can significantly reduce these unwanted interruptions.

What Are Fraudulent Calls and Why Are They a Concern?

Fraudulent calls encompass unsolicited promotions, impersonation scams, and robocalls that you didn't request. These calls can lead to identity theft, financial loss, and privacy invasions. Recognizing and mitigating these calls is crucial for personal security.

How Can You Block Unwanted Calls on Your Smartphone?

For iPhone Users:

  • Silence Unknown Callers: Navigate to Settings > Phone and enable "Silence Unknown Callers." This feature sends calls from numbers not in your contacts directly to voicemail. (consumer.ftc.gov)

  • Block Specific Numbers: Open the Phone app, go to Recents, tap the information icon next to the number, and select "Block this Caller." (consumer.ftc.gov)

For Android Users:

  • Filter Spam Calls: Open the Phone app, tap the three dots > Settings > Caller ID & Spam, and enable "Filter spam calls." This will warn you about potential spam numbers. (consumer.ftc.gov)

  • Block Specific Numbers: In the Phone app, go to Recents, press and hold the suspicious number, then choose "Block/report spam." (consumer.ftc.gov)

What Role Do Carrier Services Play in Blocking Scam Calls?

Major mobile carriers offer services to help identify and block scam calls:

  • AT&T: ActiveArmor

  • T-Mobile: Scam Shield

  • Verizon: Call Filter

These services often include caller ID, spam warnings, and auto-blocking features, though some may come with a fee. (consumerreports.org)

How Can Third-Party Apps Enhance Call Protection?

Third-party apps can provide additional layers of protection:

  • RoboKiller: This app uses advanced algorithms to identify and block scam calls, offering real-time protection.

  • Hiya: Provides caller ID and spam detection features to help users avoid unwanted calls.

  • Truecaller: Offers a comprehensive database to identify and block spam calls effectively.

These apps maintain databases of known robocall numbers and identities, helping to filter out unwanted calls. (kiplinger.com)

What Is the National Do Not Call Registry and How Does It Help?

Registering your number with the National Do Not Call Registry can reduce calls from legitimate telemarketers. While it won't stop illegal robocalls or spoofed scam likely numbers, it helps in filtering out unwanted sales calls. (consumerreports.org)

How Can You Report Fraudulent Calls to Authorities?

Reporting scam calls to the Federal Trade Commission (FTC) helps in tracking and combating fraudulent activities. You can file complaints about phone and text scams, robocalls, and telemarketers through the FTC's website. (usa.gov)

What Are Some Additional Tips to Protect Yourself from Fraudulent Calls?

  • Avoid Engaging with Unknown Callers: Do not answer calls from unknown numbers. (security.org)

  • Be Cautious with Personal Information: Never share personal or financial information over the phone unless you're certain of the recipient's identity.

  • Regularly Update Your Contact List: Keep your contacts updated to ensure that known callers ring through.

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