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.

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.

1. Sign Someone up for spam texts

Sign up for plenty of free trials

We'll go over a few methods for spamming a phone number with calls.

The first is to use spam phone call revenge services that are specifically designed for that purpose. and are two websites dedicated to making spam phone calls and messages, and while they may cost a few dollars, you should be able to complete your task.

But there is a whole list above of websites you can use.

2. Post ads online with victim phone number

This is yet another dreadful way to quickly have spam calls flood a phone number. The number will receive a large number of these calls if you create a profile on, for example, dating site, or maybe an ad for something that looks like a bargain and make the phone number public.

If you post an ad on a website like Facebook Marketplace, Craigslist, eBay, Oodle, Geebo, or Locanto with something for sale at a ridiculously low price, or if you post an ad for something people want and offer to give it away for almost free, you should get a lot of people buzzing your phone in no time.

3. Enter in Online Surveys, Forms, and Free Trial Registration

Getting spam can be similar to getting a telemarketer to call you; the difference is that it may come from more nefarious sources.

You can get a phone number into the hands of people who will call you by listing it on adult websites, gambling deals, lucky gift vouchers, and occasionally to show your interest in helping charities. 

With the number, you can also enter contests or sign up for free trials, vacations, cruises, sales, and other giveaways at random. Telemarketers would have immediate access to the number.

Using a service that specializes in spam calls may be the simplest way to sign someone up for spam calls, despite the fact that it can be expensive.

It's important to note that giving telemarketers a phone number could result in the person receiving spam calls indefinitely, which is a terrible thing to do. As a result, we recommend that you visit spam sites instead. It's a temporary solution, but it works just as well.

4. 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.

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. 

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. 

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 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.

Sign Someone Up For Spam Calls FAQs

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.

When customers for a small business's products or services are in hard-to-reach areas, or when many prospects must be contacted in order to find one interested in making a purchase, telemarketing comes in handy.

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 are where the calls are being made to or made from. Also, if the numbers are generated at random, one can "bypass" certain legislation.

Do telemarketers simply call people they come across?

No, telemarketers do not call people they learn about right away. Telemarketing is usually targeted, and lists must be created before the campaign can begin. Essentially, telemarketing is about trying to sell a product or service. So a curated list will be created which contains people in the target demographic, or maybe in a certain area.

How do you register to receive telemarketing calls?

There are several ways to register up for telemarketing calls, according to the Better Business Bureau. These are some of the possibilities: 1. You requested credit, 2. You make charitable contributions, 3. You have a voter registration card, 4. You purchased something or entered a contest and provided your phone number. If you would like to remove yourself from the register, this article contains the exact procedure to follow at the top.

Is telemarketing permitted in the United States?

Is It Illegal to Put Someone’s Phone Number Online?

Yes, it is against the law to publish someone's phone number without their permission. It can be considered harassment, especially if done maliciously – this is known as Doxing. Depending on the nature, intent, and scope of the dox, the victim may pursue legal action. It's worth noting that doxing can be legal in some circumstances. When the phone number is already publicly available or was obtained legally, for example. When doxing is deemed illegal, the offender faces a six-month prison sentence, a $500 fine, and a criminal record.

Is It Illegal to Sign Someone Up for Spam?

Can You Sell Your Phone Number?

Yes, if your phone number is memorable, you can sell it. Some companies or businesses ask network providers for catchy phone numbers, and if that number is yours, you may be compensated. Your service provider will then transfer the number to the company and issue you with a new one. On sites like numberbarn and vanity tel, you can sell your memorable phone numbers. The dark web is another place where a phone number can be sold. If a scammer obtains your phone number, they can sell it on the dark web to anyone. The phone number can also be used to access your social media and bank accounts.


There are so many prank ideas out there, but giving telemarketers your phone number has to be one of the worst. Telemarketers are notorious for making spam calls and texts to random phone numbers.

They're also good at persuading people to spend money on things they don't need. As a result, your victim will either receive several unwanted calls or will be sweet-talked into purchasing something useless.

Should you give telemarketers your phone number? Is it really necessary to go that far? Is it really worth it?

Before you sign someone up for spam, you should ask yourself these questions. If you decide to proceed, this article will provide you with some of the best ideas as well as the consequences.
