How to Stop Robocalls

How to Stop Robocalls

If you own a smartphone, chances are you’ve received one or more unwanted robocalls from unknown numbers. From illegal robocallers to spoofed ones, Trademore informs you how to block callers in order to help minimize the amount you’re receiving, or stop robocalls altogether.

Register your Number on the Do Not Call List

According to the Federal Communications Commission, it’s possible to block telemarketers when you register your mobile number to the “Do Not Call” list. Simply call 1-888-382-1222 and request to have your number added to their list. Once you’ve done this, you also have the option to block the phone numbers of frequent callers.

You also have the option of reporting numbers to the FTC (Federal Trade Commission), which works to prevent fraudulent marketplace practices. Calls that ask for unwarranted personal information should be reported to the FTC for further investigation. When you receive an illegal robocall, simply hang up. Responding to any of the requested information can lead to more calls. Go to and follow the steps to report the number.

How to Block Callers on Your Device

Android devices:

  • Open the Phone app
  • Tap the icon in the top right corner with three dots
  • Tap “Call Settings”
  • Tap “Reject Calls”
  • Tap the “+” symbol to add numbers you want to block

iPhone devices:

  • Go to Recents and find the contact you’d like to block
  • Tap the info icon next to that number
  • Scroll to the bottom of the screen and select “Block this Caller”

Third Party Blocking Apps

  • RoboKiller: this app blocks spam calls and offers pre-recorded responses that can frustrate and mislead spam callers such that they don’t continue to call. This app’s services cost $2.99/month on Android devices and $3.99/month on iOS devices.
  • Truecaller: this app blocks spam phone calls and messages by identifying unfamiliar numbers and blocking unwanted calls based on spammers or numbers you add manually. The basic app is free, but for $2.99/month you can remove ads and receive other benefits.

Don’t Answer Unknown Numbers

Of course, one of the easiest ways to stop robocalls is simply to not answer. Oftentimes scammers or recordings can ask you to select a number on your keypad or threaten you by demanding time sensitive action take place. Do not trust unknown numbers that pressure you to take action. Simply hang up and block that number on your device.

Carrier-Specific Blocking

Carriers such as Verizon offer features that can stop you from receiving robocalls and protect your privacy. Their free Caller ID Blocking service blocks your number from displaying on Caller ID for an extended period of time, or temporarily. Follow steps on the “My Verizon” app for more information on how to block callers.

Carriers such as AT&T allow customers to block unwanted calls from up to 100 numbers by pressing *61 after their most recent unwanted incoming call. They also allow customers to create a block list online through their personal account.

Sprint does not offer a free robocall blocking system, but Premium Caller ID is available for purchase to do so. Some Sprint devices do however automatically screen and block robocalls. Be sure to check in with your carrier if you would like more information on how to stop robocalls as this information may vary depending on your device.
