What is Telemarketing and why are they known as spam calls?

Telemarketing is the process of generating leads, making sales, or gathering marketing data over the phone. Telemarketing is a particularly useful tool for small businesses because, compared to personal selling, it saves time and money while providing many of the same benefits in terms of direct contact with customers.

But why are these known as spam calls? This is because most of these calls are unsolicited, meaning that these people have not opted-in to these calls. Whether such calls are legal or not is a bit of a grey area, because such legislation typically depends on the area where the calls are being made to or made from. Also, if the numbers are generated at random, one can “bypass” certain legislation.

National Do Not Call List

If your number has landed on a telemarketing or a phone number spammer list, there are some remedies you can do especially in the United States.

Remove Number From Telemarketing Lists

Let’s say that your number is now on a telemarketing list or getting spammed by numbers and you want to remove yourself from this list without having to change your number. While you can choose to silence unknown callers, it’s best to get off these lists of spammy incoming call.

In the US, there is something which is called the National Do Not Call Registry.

To stop harassing sales calls, the National Do Not Call Registry was set up. Your home or mobile phone number can be registered for free on this list.

The chances are that the calls you receive are from fraudsters if you’ve already entered your phone number to the Do Not Call Registry but are still receiving a lot of unsolicited calls. To learn how to handle incoming calls, read about call blocking. If you answer one of these calls, end the conversation and notify the FTC of the incident.

Maybe you’re in a bad mood and you want to sign ex up for spam emails? While these may appear to be two separate topics, we believe there are significant parallels between the two, as many of us consider Telemarketer calls to be spam calls so this article will focus also on how to sign up phone number for spammer calls.

How to Give a Phone Number to Telemarketers

When we overshare our phone numbers on public profiles like Facebook pages, websites, and forums, we unwittingly give them to telemarketers, or what some people know as a call spam bot.

It can also happen if you accept some terms and conditions without reading the fine print, or when credit bureaus and charities sell your phone number.

It could also be caused by events beyond your control, such as when large corporations sell your personal information to third parties.

However, there are a few things you can do if you want your phone number or email to be in the hands of telemarketers on purpose.

Signing up for free trials with real phone numbers

When you see free trials, you might think this is a great thing. But the moment you see “enter phone to subscribe” you might want to give it a miss because free trials with a phone number or email are a sure way to add somebody to a marketing list. You must provide a valid email address and phone number in order to receive a free trial of certain products and services. Some giveaways and other services promise you something valuable in exchange for your phone number and email address.

They’ll most likely call you again, telling you that you didn’t win but that you can take advantage of other offers. This includes online surveys, and… well, you get the idea. You just give your phone number to as many of these guys as possible, and you should be able to spam your phone number with calls as soon as possible.

Using ANI or Automatic Number Identification Can Land Your Number on Telemarketing Lists

Calling 800, 888, or 900 is the easiest way for most people to get their phone numbers into the hands of telemarketers and have them sign them up for spam calls. When you do, the Automatic Number Identification system records your phone number. This will identify and store the phone number you have used to call, as well as crawl a web of digital markers linked to you, and you will probably begin receiving spam calls from telemarketers.

Spam Phone Number Revenge

While getting on a telemarketing list is annoying, the intent of this is different from performing a spam phone number revenge. While telemarketers might operate in a grey area of the law, a spam phone number revenge is where you intentionally want to flood somebody’s phone with text simply to ruin their day or maybe even their usage of their phone number.

Let’s say you feel wronged and you want to sign ex up for spam for spam calls. A spam phone number revenge can easily get out of control, with the number literally ruined by the constant barrage of messages and calls, so do proceed carefully. While most of these services are anonymous, and you can anonymously sign someone up for spam, keep in mind that if you are caught (there are various ways in which this can happen) you might also be charged with misuse of electronic equipment or other charges, so be aware of the risks.
