You can stop spam calls by blocking unknown or suspicious numbers on your phone. Most smartphones have built-in settings that let you silence or block calls from numbers not in your contacts. This stops robocalls before they reach you.
Mobile carriers also offer free or paid tools to detect and filter spam calls. Services like AT&T Call Protect, T-Mobile Scam Shield, or Verizon Call Filter help label or block suspicious numbers automatically. These tools update regularly to catch new scam numbers.
Another way to reduce spam calls is by using third-party apps like Hiya, RoboKiller, or Truecaller. These apps use large databases to block known spam callers. You can also report spam calls to the FTC or FCC, which helps stop future scams.

What Are Spam Calls and Why Are They Increasing?
Spam calls are unwanted phone calls that often include recorded messages or scams. These calls are usually made by automated systems known as robodialers. Companies and scammers use them to reach thousands of people in a short time. The goal is often to sell something, collect personal data, or trick people into sending money.
Many spam calls pretend to come from real businesses or government agencies. This trick is called caller ID spoofing. It makes the number on your screen look familiar or trustworthy, even when it’s not. For example, the call might appear to come from your local area code or a known company.
The number of spam calls has grown fast in recent years. According to YouMail, Americans received over 50 billion robocalls in 2023. This increase is caused by cheap calling software and the ability to hide real caller identities. Scammers take advantage of this to make more calls with less risk of getting caught.
There are also different types of spam calls:
- Scam calls: Try to steal money or personal information.
- Telemarketing calls: Try to sell products or services without permission.
- Legit robocalls: Schools or pharmacies might use them for reminders, which are allowed.
How Can You Identify a Spam or Robocall?
You can identify a spam or robocall by checking for common warning signs. These include a prerecorded message, a robotic voice, or a caller who asks you to press a button or give personal details. Many scam calls sound urgent or threatening to create fear and push you to act quickly.
Caller ID spoofing is another red flag. The number may look local or appear to come from a trusted company or government agency. In reality, scammers use software to fake the caller ID and trick you into answering. Some even pretend to be banks, the IRS, or delivery services.
Not all robocalls are illegal. Calls from schools, pharmacies, or airlines that share useful information are allowed. But if a call tries to sell you something without your written permission, it’s illegal and likely a scam. Recognizing these signs helps you avoid falling for fake or harmful calls.
What Immediate Actions Should You Take When You Get a Spam Call?
When you receive a spam call, the best action is to hang up right away. Do not speak, press any buttons, or follow instructions. Responding in any way can confirm that your number is active, which may lead to more spam calls.
If the call goes to voicemail, don’t call the number back. Scammers often use fake numbers or charge high fees for returning calls. Let unknown numbers go to voicemail and check if the message seems real before taking any action.
You can also block the number directly on your phone. Most smartphones allow you to block recent callers with a few taps. This won’t stop all spam calls, but it reduces repeat calls from the same number.
How Can You Block Spam Calls on Your Mobile Device?
You can block spam calls directly from your smartphone settings. On an iPhone, you can use the Silence Unknown Callers feature, which sends unknown numbers straight to voicemail. On Android phones, you can block individual numbers or turn on Caller ID and Spam Protection.
Most mobile carriers offer built-in tools to block or label spam calls. For example:
- AT&T Call Protect: Blocks known fraud calls and warns about suspected spam.
- T-Mobile Scam Shield: Shows “Scam Likely” on suspected calls.
- Verizon Call Filter: Detects spam and lets you block or report it.
You can turn on these services through your carrier’s app or account settings. Some features are free, while others require a monthly fee. Blocking tools update regularly to stay ahead of new scams. Using your device and carrier tools together offers stronger protection.
What Are the Best Apps and Tools to Stop Spam Calls?
Several third-party apps help block spam calls using large databases of known scam numbers. These apps detect suspicious calls and block them before they reach you. Some of the most effective options include Hiya, RoboKiller, Truecaller, and Nomorobo.
Each app offers different features:
- Hiya: Identifies caller names and blocks spam automatically.
- RoboKiller: Uses answer bots to waste scammers’ time.
- Truecaller: Shows caller ID and allows community-based spam reporting.
- Nomorobo: Blocks robocalls and lets legal robocalls, like school alerts, come through.
Some apps are free, while others offer advanced features through subscriptions. These tools update in real-time and rely on user reports to stay accurate. They work well alongside your phone’s built-in settings and carrier services.
How Can You Report Spam or Scam Calls?
You can report spam or scam calls to help authorities track and stop illegal callers. In the U.S., the main place to report is the Federal Trade Commission (FTC). If the call violated the Do Not Call rules, you can also report it.
You can also report spam calls to the Federal Communications Commission (FCC). The FCC handles complaints about caller ID spoofing, robocalls, and unwanted texts. These reports help build cases against repeat offenders.
Most call-blocking apps and mobile carriers also allow in-app reporting. For example, apps like RoboKiller or Hiya let you flag calls as spam. Carriers like Verizon, AT&T, and T-Mobile use this data to update their spam protection systems and block calls more effectively.
What Role Do Carriers and the Government Play in Stopping Robocalls?
Carriers and government agencies work together to reduce robocalls using technology and regulations. U.S. mobile carriers now use SHAKEN/STIR protocols, which help verify caller identity and block fake numbers. This makes it harder for scammers to spoof legitimate phone numbers.
The Federal Communications Commission (FCC) enforces robocall rules and requires carriers to block illegal calls. It also fines companies that break these laws. The FTC runs the National Do Not Call Registry, which helps reduce telemarketing calls to registered numbers.
Industry groups like the CTIA also support efforts to stop robocalls. They work with carriers to improve spam detection tools and educate the public. These combined efforts help protect users, but ongoing updates and user reports are key to staying ahead of new scam tactics.
