How To Block Scam Calls: Solution

So, what is being done about this problem? Governments around the world have passed legislation to regulate and punish robocalls, telemarketers, and fraudsters. There has been some success, but not fully just yet. For example, in September 2019 a $267 million final judgment was awarded against a debt collection agency that used auto-dialers to make over 500,000 unsolicited robocalls. It was found that their practices violated the Telephone Consumer Protection Act (TCPA), the Fair Debt Collection Practices Act (FDCPA), and the California Rosenthal Fair Debt Collection Practices Act.


Lawsuits and government sanctions are good for after the fact, but how do you stop scam calls and texts from getting to your phones in the first place? Keep reading for information on how to halt these scammers in their tracks.

Here is a list of tips on how to stop scam calls (and here is how to report a scam number):

  1. Sign-up for the Do Not Call Registry.
  2. Block all unknown numbers.
  3. Block specific numbers.
  4. Use your wireless service provider’s call blocking tools.
  5. Use third-party scam blockers.
  6. Report unsolicited scam calls.

Let’s get into details and find out how to do every single thing mentioned above.

1. Do Not Call Registry

The first, most obvious way to protect yourself is to sign up for your country’s national do not call registry. You may have heard this before, but it’s a good start to reduce the phone scams. What is the Do Not Call Registry? It is a list of personal phone numbers that telemarketers are not allowed to call. If they do, it is punishable by a fine. Not every country has a do not call registry, unfortunately. Here is a small sample of those that do, along with links.

  1. United States — National Do Not Call Registry
  2. Canada — National Do Not Call List
  3. United Kingdom — Telephone Preference Service
  4. Australia — Do Not Call Register


It should be noted that these lists are most effective against telemarketers, and only then if they care to follow the rules. If you want to see results, make sure you report numbers that continue to call you after you are on the registry for the required amount of time.

However, be careful when signing up to avoid a potential fake Do Not Call Registry.

2. Block All Unknown Numbers

If your phone is being blown up by scam calls all day long, you may want to take the drastic step of blocking all unknown numbers that call your phone. iPhones with iOS 13 or higher have a feature called Silence Unknown Callers. It automatically sends every call from a number not saved in your contacts to voicemail.

They still appear in your recent list and if they do not leave a voicemail, you retain the option to look the number up and determine if it is a call you should return. To set this up on your iPhone, all you have to do is go to Settings>Phone and turn the switch to on.


Some Android smartphones allow you to block all unknown numbers, too. If your Android device has this feature, the most common way to access it is by opening the Phone app and tapping on the settings menu. You then click on Blocked Numbers and there should be a switch to turn on blocking calls from unidentified callers.

As with iOS 13 and above, those calls will go straight to your voicemail and still appear in your recent call history. For more device-specific information about how to stop scam calls, check the documentation that came with it or go to the manufacturer’s support page.

3. Block Specific Numbers

For those who just get scam calls once in a while, blocking specific numbers is a good option and it doesn’t take much time at all. Starting with iPhone owners, all you have to do is open the Phone app and go into the Recents menu. Then, tap Info Icon>Block this Caller>Block Contact. You can probably do this in less than 30 seconds.


Android smartphone instructions for blocking individual numbers vary between the different devices and Android versions. Generally, you open the phone app and go into the recent calls list. Then, tap the number to be blocked. Somewhere there should be a list of options, including ones to block a number (and possibly report it as spam as well). All you have to do is tap on the block number option and confirm.

However, sometimes cybercriminals hijack other’s people’s numbers and use them to perpetrate their scams. So, don’t answer a call from your own number, or from a number that looks very similar to yours.

4. Use Your Wireless Service Provider’s Scam Call Blocking Tools

In answer to the question of how to stop scam calls, the Federal Communications Commission (FCC) is cracking down and allowing phone companies to use algorithms to compare incoming calls to massive databases of numbers and automatically block the ones that are suspected of being unwanted or illegal. They are also requiring phone companies to utilize caller id authentication protocols to decrease spoofing (illegally disguising an unwanted call by using a number from a known, trusted source).

Briefly, here is what each of the major wireless service providers is doing to comply with the FCC and help you fight scam calls.


Postpaid T-Mobile and Metro by T-Mobile subscribers (prepaid plans are excluded) get free access to Scam ID and Scam Block. Scam ID will label incoming suspicious calls as “Scam Likely” on the caller id and then you can decide if you want to risk answering it. However, if you want to completely block all scam calls before they reach your phone, you can enable Scam Block. For a fee, T-Mobile also offers a Name ID feature which will give you a caller’s real name and location and greater control in how calls are blocked.


AT&T provides an app called Call Protect. The free, basic version is automatically added to AT&T Mobility plans. It alerts you to potential scam calls and allows you to block them. There is also Call Protect Plus. It is a paid version that has additional tools like Reverse Number Lookup and enhanced Caller ID. For more details and directions on how to block scam calls on different kinds of phones, customers should visit the support section of the AT&T website.


Using the My Sprint app, customers can block specific numbers from unsolicited calls. Sprint also has a paid service, the Premium Caller ID app. For a monthly fee, you can screen unknown callers.


Verizon is fighting scam calls by giving postpaid customers with compatible devices a free service called Call Filter. This service labels incoming potential scam calls, automatically blocks robocalls based on your chosen risk level, and lets you easily report calls from unknown numbers.

You can get additional features by paying a small fee for each line. Those extra features include an editable personal spam caller list and Caller ID that gives you a caller’s real name and location.


5. Use Third-Party Scam Call Blockers

Unfortunately, if you are not a subscriber of one of the 4 major wireless service providers or if you are on a prepaid plan, you probably will not have access to the scam call prevention tools those companies offer. That is where third-party apps come in. The best features are usually hidden behind a paywall, but the basic versions (if offered) are still useful to have. Many times, though, the fee-per-month is low and is worth paying if you really like the app.

Here are a few examples of third-party call blockers.

  1. Robokiller for iOS and Robokiller for Android
  2. Nomorobo
  3. YouMail Voicemail & Spam Block
  4. Truecaller
  5. Hiya Caller ID and Block


6. Report Unsolicited Phone Calls

It is important to know how to report phone scams and other unsolicited calls. While it may not result in immediate action, it will help groups like the FCC and your wireless service provider improve their databases which they use to filter out the scam calls. Enough people reporting the same callers over and over could also lead to future fines. Also, it could generate possible class-action lawsuits on behalf of the victims.

Visit the FCC and your provider’s website for more details on how to report scam calls.

What Should You Do if You Answer a Scam Call?

You can follow all the relevant advice on how to block scam calls, but a small number of scammers will still likely get through. So, what do you do if you answer one? Experts are divided. Some believe you should hang up and say nothing. Others say that you should be ready to convince them that your number is not viable, like by having a pre-recorded “this number is not in service” message ready to play.


Most, however, agree on the basic tips below about how to safely deal with risky calls.

  1. If you were not expecting a call or are suspicious, do not give out personal information over the phone. This includes passwords, account numbers, your mother’s maiden name, Social Security numbers, and any other identifying information someone could use to potentially defraud you.
  2. Do not answer calls from unknown local numbers. Some scammers will hide their real phone numbers using technology like Caller ID Spoofing. This allows them to put in whatever phone number they wish. It is usually one that has the same area code as yours. This also can include numbers that are known and trusted by you, by the way. If it is legitimate, hopefully, they will leave a voicemail and you can get back to them at a later time.
  3. If you are asked by a recording or a live caller to press a button to remove yourself from a calling list, do not do it. It’s a trick to see if your number is viable and can lead to future scam calls.
  4. Should someone pressure you to take any action now, such as give information or make a payment, be cautious.
  5. Do not answer questions with “Yes,” especially if the call is suspicious. Be careful about saying your full name, too. Scammers can use this to try to create and enforce agreements which could cost you a lot of money.
  6. Be on guard with unexpected callers that claim to be from a government agency or a company, particularly if they are seeking payment. It is best to extricate yourself from the situation, then look for the number on a bill or an official website to call and verify the request was real. You should have received a statement in the mail before any legitimate phone calls.

    I just let them talk without giving a sign of life. They soon put the phone down.
    At other times I repeatedly ask them to repeat their names … they soon hang up giving me up for a lost cause.

  2. Charlotte Mitchell says:

    Thank you SO much for the invaluable information about scams. I’ve always been extremely careful about online and/or phone scams, but there’s always something new and you let us know about it. I do want to add that both my landline and cell phone numbers have been on the “Do Not Call” registry for years, but it hasn’t stopped the frequency of the calls. I simply don’t answer if I don’t recognize the number/caller. My theory is if it’s legit, the caller will leave a message and the call can be returned. If not, the number is checked and blocked immediately! Thanks again!

    Is there a way to block unknown numbers on a land line?

  4. Joyce Mitchell says:

    I have calls everyday from local #’s telling me they are so and so on a recorded line, They ask if you can hear them ok? That’s when I hang up the phone and block number. Happens every day. Also I received a letter from a so called attorney that references a case # and tells me I am being arrested for failing to pay back an on line loan that I never received. I don’t know what to do about it. Thanks for a heads up.

    Also, be especially careful about answering “game” surveys on social media. A common “game” is to ask a series of questions like, favorite food, last address you lived at, mothers favorite food etc. These answers can be planted by scammers to use against you to answer your security questions to accounts or get enough information to make you believe they’re a valid agency when they call you.

  6. Colin Wilkinson says:

    One of the things not covered here and is used quite extensively by a lot of scammers is, they use unallocated phone numbers, ie. if you ring back you are told that it is an unlisted number. so how do you stop these callers?.
