What are the different types of spam phone calls?

There are many types of spam calls, including telemarketing, robocalls, spoofing, and IRS and insurance scams.

what are the different types of spam phone calls

You’ll receive fewer spam calls if you engage less with spam. If you answer a spam call, your number may be added to a list of numbers that commonly answer, respond to, or fall victim to scams. 

The fraudsters think these are the most likely numbers to provide sensitive information, so they target them more often.

1. Spoofing calls

A spoofing call is one that imitates an organization or a local number. People will receive calls from familiar numbers, which are used for scams and mimicking advertisements.

2. Telemarketing calls

Telemarketing calls are often used by companies and enterprises to promote their products, services, and companies to potential customers. They can be intrusive because they are repeated without the user’s consent.

3. Charity scams

People are receiving fake calls pretending to be from charities asking for donations for causes such as diseases and natural disasters.    

4. Political calls

A political call is a scam that manipulates and betrays the people for political purposes. A pre-recorded message can be used to trick people into voting for them, giving personal information, and making donations. 

5. Reminder calls

Using reminder calls, you can remind yourself of important events, such as meetings and appointments, by customizing the day, time, and location. These calls are misused by scammers to remind victims of their scams and phishing schemes. 

6. Loan scams

Using this robocall, a caller offers loans and credit cards for a small up-front fee to individuals with poor credit scores. Their goal is to get the upfront fee, but they won’t actually make the loans happen. 

7. Travel scams

Calls like this offer low travel and vacation costs; interested parties put in their credit card information, which can result in the loss of information and money. 

8. Customer care scams

In this robocall, a business agent represents high-profile brands or organizations. Various fraudulent activities will be attempted to get your sensitive information and personal information. 

Why do you get Spam Calls?

You are getting spam calls because you might have answered several robocalls, and the spam caller must have gotten the hold of your number and sold it to other scammers or telemarketing companies. 

Be careful, Spammers are always trying to trick recipients into giving up sensitive information or money. They use different techniques to get information from the users, such as credit card numbers, passwords, or personal details.

why do you get spam calls

Let’s know how your number ends up with spammers, and they bombard you with unwanted calls.  

  • Your Number is Sold in Scammer Groups

Your number may have been sold to a scammer group if you receive a lot of unwanted calls. When your number is sold, it is used by all scammers to make scam calls.

The fraudulent individuals attempt to deceive you in many ways under the guise of professionals. Some may pose as insurance agents, salesmen, car dealers, technicians, etc.

  • Your Number is Public

Businesses should make their contact information available to customers and potential customers. Spam lists are created from publicly available information, such as phone directories, websites, or social media profiles. Personal numbers, however, should remain private. Scammers will exploit them if you list them in the public domain.

These days, there are hundreds of apps that can harvest your data, including your phone number. As a result, the data is usually leaked to scammers when we accept their terms without thinking twice. 

  • You May Have Picked Up an Unwanted Call

While scammers are hitting and trying phone numbers to find a victim, you might pick up a call. Scammers also target you because you picked up their call once. You look like a good target, so they call you repeatedly, as it is taken as an invitation.

To increase their chances of engaging you, they may call you from different numbers. You are left alone only when they are certain there is no chance of success.

  • Online Forms and Surveys

Whenever you fill out an online form or survey, your contact information can be collected and used for spamming purposes.

  • Don’t fall for it: Be careful not to give your personal information or make digital payments. It is a trick to steal your information if you reply or click the links of the texts related to financial information. Also, do not answer questions with yes or no answers

What Can You Do if Spam Callers Already Have Your Virtual Phone Number?

If the spammers already have your virtual phone number, you can follow the given steps to avoid spam calls. 

what if spam callers have your phone number
  • Change the number: You can eliminate all spam from your virtual number by simply getting a new number. You cannot do this if your established business number has been with you for years. Unless you haven’t used it for a long time, or it’s not the number people call to reach you, you can remove it. Replacing the number will likely solve the spam problem immediately as soon as you register it.
  • Add a Call Menu or Auto Attendant: Using an auto attendant to protect against solicitation bots is one of the most common reasons for people to want an auto attendant service. They cannot reach an actual phone by calling an auto attendant since they must press a number to ring someone’s phone, which they cannot do.
  • DNC Registry: Putting your virtual phone number on the National Do Not Call Registry is something you should do with any number you own as a precaution:
  • Create a list of blocked phone numbers: When you get a number that attracts spammers and solicitations, you’re often faced with an ongoing battle to manage unwanted calls. Your call history may need to be manually blocked if your problem is extensive. The problem is that this may need to be done continuously.
  • Contact Your Provider: If you are receiving excessive harassing calls, you can contact your virtual phone service provider for assistance with escalating the issue. Once you’ve exhausted all your options to solve the spam issue on your own, that might be the best course of action.
