How to Block Repeated Local-Looking Calls on Your US Phone Number

Receiving repeated calls that appear local can be both frustrating and concerning. These calls often originate from robocallers or scammers who use local area codes to increase the likelihood of you answering. Fortunately, there are several strategies you can employ to block these unwanted calls.

What Are Local-Looking Calls and Why Do They Occur?

Local-looking calls are those that display a caller ID matching your area code or even your own number. This technique, known as "caller ID spoofing," is commonly used by robocallers and scammers to deceive you into answering. By appearing local, they exploit the natural tendency to trust familiar area codes. (consumernotice.org)

How Can I Block Local-Looking Calls on My Phone?

1. Register with the National Do Not Call Registry

Adding your number to the National Do Not Call Registry is a free service that aims to reduce unsolicited sales calls. While it doesn't block all unwanted calls, it can decrease the volume of legitimate telemarketing calls. (consumer.ftc.gov)

2. Utilize Call-Blocking Apps

Third-party applications can help identify and block robocalls. Apps like RoboKiller, Hiya, and Truecaller maintain databases of known spam numbers and can filter out unwanted calls. These apps often provide real-time alerts and allow you to report suspicious numbers. (kiplinger.com)

3. Enable Built-in Call Blocking Features

Many smartphones offer native features to block unknown or suspicious calls:

iPhone: Go to Settings > Phone and enable "Silence Unknown Callers." This feature sends calls from numbers not in your contacts directly to voicemail. (usa.kaspersky.com)
Android: Open the Phone app, tap the three dots, select "Settings," then "Block Numbers." Here, you can enable options to block calls from unknown numbers. (usa.kaspersky.com)

4. Contact Your Mobile Carrier

Many carriers offer services to help block robocalls:

AT&T: ActiveArmor provides spam call blocking and fraud call blocking.
Verizon: Call Filter identifies and blocks spam calls.
T-Mobile: Scam Shield offers scam call blocking and protection.

These services often have free versions with basic features and paid versions with advanced options. (makeuseof.com)

5. Report Unwanted Calls

If you receive a robocall, report it to the Federal Trade Commission (FTC) through their website. While this won't stop the specific caller, it helps authorities track and take action against illegal robocallers. (consumer.ftc.gov)

What Should I Do If I Receive a Suspicious Call?

Don't Answer: If you don't recognize the number, let it go to voicemail. Answering can confirm to the caller that your number is active. (consumernotice.org)
Don't Engage: If you do answer and it's a robocall, hang up immediately. Engaging can lead to more calls.
Don't Share Personal Information: Never provide personal or financial details over the phone unless you're certain of the caller's identity.

How Effective Are These Methods?

While no solution guarantees 100% protection against robocalls, combining multiple strategies can significantly reduce their frequency. Utilizing call-blocking apps, enabling device features, and leveraging carrier services can provide a comprehensive defense against unwanted calls.

By proactively implementing these measures, you can regain control over your phone and minimize the disruption caused by local-looking calls.
