Have you ever received spam calls from an unknown number? There are situations where the number you get a call from is often flagged as a “risk call.” This means it could pose a potential risk for the receiver. That is referred to as a spam risk call. This guide explains everything about what risk calls are and how to stop them.  

Unknown callers who either searched for your phone number online or obtained it via call records are the ones making these unsolicited calls. However, if you weren’t actually expecting a call from anyone unknown, you could just ignore it. 

Even though your call providers take active measures in blocking spam or risk calls, there is no guarantee that they are 100% accurate. Some carriers often get the numbers mixed up and flag legit calls are spam or mark the phone numbers as illegal or dangerous. Even though that is a minor setback, there are still ways for you to block actual risk calls and enhance overall security. 

Is There a Reason Why Spam Risk Calls Appear on Your Phone?

Yes and no. In the majority of cases, unknown callers target masses excessively with spam calls and text messages for vindictive reasons. This is one of the biggest fraud techniques to trick users into handing over sensitive information, which could lead to loss of money. 

The rate of these mass spam call attacks is uncounted for, and the numbers keep rising. 

According to CNBC, in 2022, around 70+ million Americans were targeted and fell victim to risk caller scams, and around $40 billion was lost in the mix. The degree and techniques of these scams or cyberattacks vary, but again, it all depends on the unknown calls you receive and the information you hand out. 

But how do these attackers get their hands on your number? 

In the majority of cases, your phone number might’ve been pulled out by fluke via a phone number generator. Other ways include your number being leaked by a known or sanctioned source.

 However, these are just simple ways of scam risk callers getting their hands on your numbers. There are other, more polished methods of your phone numbers being targeted. This includes hacking your phone via illegitimate apps and links, stealing from your phone carrier, etc.  

Are Caller Numbers that are Flagged as a Spam Risk Reliable?

Yes and no. There are chances that you will receive a call from an unknown number, and it is labeled as “spam risk.” The chance that these calls are actually from scammers is 50-50. 

There is something called machine learning that most phone carriers use to log and label numbers as a spam risk call scam warning. 

However helpful this may be, it’s not always 100% reliable. At times the number dialing you might be from an authentic source but got accidentally flagged as a risk. In these situations, you need to take note of the phone number and the times you received a call from it.

You must always check to see if this was a number logged on your phone but not registered. Another way is simple; let them leave you a text message. 

Before we jump to how mobile carriers detect risk calls, let’s first dive into how you can stop a spam risk call from taking place.  

Preventing Risk Caller Spam Calls on Your Devices

There are countless times when you might’ve encountered unknown spam calls. People picking up the call is a  ⅘ chance. 


It’s because you’re probably expecting a job offer, an emergency contact, or more. However, some of us accidentally answer spam calls without even thinking twice. 

Always remember, if the call is urgent, you will receive a text message stating who the caller is and with a reason. If it’s urgent from a place of work, the number of calls won’t exceed rapidly within those 10 minutes. 

There are features on smartphones where you can silence a call or stop it. But, if you’re experiencing a “whose number is this spam risk call,” then it’s better that you block it off entirely. Here is how to get started: 

How to Block Spam Risk Calls on Android

If you’ve got an Android smartphone and are looking for a way to stop suspicious spam calls, the best way to do it is to flag them with the “spam risk” label.

  • On your Android phone, go to “Settings.” 
  • Tap on “Apps and notifications.” 
  • Select “Default apps.” 
  • Now, under the “Default apps” section, select “Phone by Google” as the default app.

How to Prevent a Spam Risk Call on Landline

This guide on stopping scam risk calls on landlines is mostly for the people in the USA. The United States is often listed high on the charts for falling victim to scam calls, losing the most money in billions of dollars. These stats are combined from targets on both smartphones and landlines. 

To maneuver around this, there is a registry to which you can send your number. This is a smart way of preventing telemarketers from targeting you. 

For this to work, you will have to register your phone number with the “National Do Not Call Registry.” You can call them at 1-888-382-1222 or contact them at

This includes credit card numbers, ID card verification codes, your home address, etc. An authentic source or caller would never ask for this information over a call or text. 

How do Phone Carriers Detect Spam Risk Calls?

Most phone carriers often detect scams or risk calls through prolonged machine learning. These techniques utilize analytics for behavioral patterns of phone call numbers and track them for suspiciousness. 

This means that if one number calls many people aggressively, it is tracked and logged as a risk call number. Mobile phone carriers maintain all these call number records and aid users in dodging risky calls. Through this detection, you can actively block the calls from targeting you again. 

Are There Any Risks When You Pick Up a Spam Risk Call?

It’s a fact that many people often pick up unknown calls for whatever reason. In the case of emails, there is always a junk folder with requests from unknown senders. 

Before you open any email, there is a warning notifying you not to respond or click on any links. It is so you avoid getting phished into a scam or cyber threat.

 The same is the case with phone calls. Unknown Caller IDs who contact you are marked as “Spam Risk.” It’s to ensure that you don’t fall trap. Here are some risks associated with answering a spam risk call number: 

  • When you pick up a spam call, your number is logged into the attacker’s system. This will tell them that your number is active. Through this, you will receive more spam calls from different numbers. 
  • If, by chance, you do give sensitive information, you could lose a lot of money and data or experience identity theft
  • Always wait for the caller to text you if it’s urgent. Sometimes, simply picking up a call can hijack the data on your phone.
  • Some risks with picking up a include your voice being recorded and used against your will.
