Agencies like the Federal Trade Commission (FTC) and Federal Communications Commission (FCC) are working on a comprehensive solution, but in the meantime, it’s important to know what a <a href="https://www.robokiller.com/block-spam/spam-calls" target="_blank">spam call</a> is and how you can handle it.<br/><br/>Here's everything you need to know about how to recognize and block unwanted spam calls, protect your personal information, and fight back against scammers.</p><h2 id="what-is-a-robocall" class="heading-20">What is a spam call?</h2><p class="pcr-paragraph">We use the term “spam call” to refer to unwanted and unsolicited phone calls that try to get something of value out of the target. Spam calls generally include sales pitches or attempt to distill personal information. All spam calls can be annoying, but some can also be dangerous.<br/>‍</p><h3 class="heading-19"><strong>How spam calls affect you</strong></h3><p class="pcr-paragraph">Spam calls aren’t just irritating, but often lead to severe consequences like compromised online accounts, financial losses, and even identity theft. Many spammers are out to swindle usernames, passwords, and other sensitive information they can use to steal from their targets or sell to other scammers.<br/><br/>If a scammer gets hold of the right information, they can take control of your:<br/>‍</p><ul role="list" class="list-2"><li class="list-item-2">Bank accounts</li><li class="list-item-2">Credit cards</li><li class="list-item-2">Online shopping accounts</li><li class="list-item-2">Social Security Number</li></ul><ul role="list" class="list-2"><li class="list-item-2">Identity</li></ul><p class="pcr-paragraph">Once the damage has been done, it may be impossible to reverse. That’s why it’s critical to understand how to spot and protect yourself from dangerous spam calls.</p><h2 id="types-of-spam-calls" class="heading-20">Types of spam calls</h2><p class="pcr-paragraph">As technology evolves, so do spammers’ techniques. Spam calls come in several different forms, and it pays to recognize not only what a spam call is, but which ones you should worry about.<br/>‍</p><h3 class="heading-19"><strong>Telemarketing calls</strong></h3><p class="pcr-paragraph">Although annoying, legitimate telemarketing calls are legal — unless you’re on the National Do Not Call Registry. If you’ve registered your number, telemarketers are not allowed to call you and face steep penalties if they do. These penalties don’t do much to deter overseas scammers, however, so the Registry won’t protect you from them. If you get a call claiming to be from a telemarketer, there’s a good chance the caller is a fraud.<br/>‍<br/></p><h3 class="heading-19"><strong>Robocalls</strong></h3><p class="pcr-paragraph">A <a href="https://www.robokiller.com/blog/robocalls" class="link-121"><strong>robocall</strong></a> is an automated call that uses a pre-recorded message. Legal robocalls are often useful, like appointment reminders or school-closing announcements, but the majority of them are illegal. Robocalls are illegal when they try to sell you something, solicit information, or contact you without your written consent.<br/></p><div class="rd-left-border-green-div"><h4 class="heading-19">What is a robocall?</h4><p class="pcr-paragraph">A robocall is any call you pick up or receive a voice message from — whether on a landline, a mobile phone, or a connected personal device — where you hear a recorded message instead of a live person. The message is usually read by a real person but has been pre-recorded.</p></div><div class="rd-left-border-green-div"></div><p class="pcr-paragraph">Spammers and scammers use robocalls to steal personal information that can be used to obtain money, assets, or your identity itself. They may impersonate legitimate businesses or even government agencies to create a sense of familiarity or authority. Because of affordable auto-dialing technology, they can place thousands of robocalls per day and expect a high return on investment.<br/>‍<br/></p><h3 class="heading-19"><strong>Scam calls</strong></h3><p class="pcr-paragraph">Spam calls that seek to defraud people by stealing personal or financial information are <strong>scam calls</strong>. This type of spam call is the most dangerous and is always illegal. Fraudulent telemarketing calls and illegal robocalls often fall into this category, and there are many specific forms.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">IRS scams</strong></h4><p class="pcr-paragraph">Getting an unexpected call from a government agency can be shocking, which is the idea behind <a href="https://www.robokiller.com/scam-call-alerts/government#title4" class="link-122"><strong>IRS scams</strong></a>. Scammers may pose as the IRS, calling to collect a debt and hoping you’ll be eager to pay the balance. In reality, the IRS won’t call you unless you owe money and have been ignoring the letters they’ve sent through the mail.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">AI scams</strong></h4><p class="pcr-paragraph">Artificial intelligence has recently become more accessible, and scammers have wasted no time using it to their advantage. <a href="https://www.robokiller.com/blog/ai-scams-voice-cloning" class="link-123"><strong>AI scams</strong></a> can be especially scary because of voice cloning, in which scammers use convincing replicas of people’s voices to target their friends and family for information or cash. If you get a call that sounds like a loved one in trouble, call that person and the police.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">Charity scams</strong></h4><p class="pcr-paragraph">Some scammers pose as <a href="https://www.robokiller.com/scam-call-alerts/veteran-charity" class="link-124"><strong>charities for veterans</strong></a>, cancer research, or other noble causes that people would be glad to support. Unfortunately, these donations — and your information — go right into the pockets of criminals. Do your research before donating to an unfamiliar charity, and never give out your payment details over the phone.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">Travel scams</strong></h4><p class="pcr-paragraph">People were eager to travel again after the stir-craziness of the COVID-19 lockdown, and scammers took the opportunity to target people with <a href="https://www.robokiller.com/scam-call-alerts/travel" class="link-125"><strong>fake vacation packages</strong></a>. Discounted rates seemed logical coming out of an extended pause in the industry, but these scams continue to be too good to be true. If you’re offered a deal on a trip, be cautious and do your research to verify its authenticity.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">Loan scams</strong></h4><p class="pcr-paragraph">Student loans are a source of confusion and distress for a generation of borrowers who struggle to make payments, making them low-hanging fruit for scammers who prey on the vulnerable. <a href="https://www.robokiller.com/scam-call-alerts/student-loan" class="link-126"><strong>Student loan scams</strong></a> have been historically popular for this reason, but scammers offer people fake solutions to all types of debt. Beware of random offers that sound too good to be true.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">Tech support scams</strong></h4><p class="pcr-paragraph">We depend on our devices for just about everything, so we act quickly when something goes awry. <a href="https://www.robokiller.com/scam-call-alerts/tech-support" class="link-127"><strong>Tech support scams</strong></a> exploit that vulnerability by alerting you to a security breach, technical malfunction, or other fake issue that might require a change of password or even remote control of your device. Real tech support generally doesn’t call you. It’s you who calls <em>them</em> if you have a problem.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">Free trial scams</strong></h4><p class="pcr-paragraph">A free trial is a good way to find out if you’re interested in a product or service, but not if it puts your sensitive information on the line. You might get a call offering an unbelievable product and a free trial or sample to make sure you like it — you just have to pay for shipping and handling. However, <a href="https://www.bbb.org/all/scamstudies/free_trial_scams/free_trial_scams_full_study" class="link-128"><strong>there may be fine print</strong></a> that signs you up for monthly shipments or requires you to return the product within a week to avoid a charge. In other cases, the scammer might sell your credit card information.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">Health insurance scams</strong></h4><p class="pcr-paragraph">Some <a href="https://www.robokiller.com/scam-call-alerts/health-insurance" class="link-129"><strong>health insurance scams</strong></a> offer low rates on plans and discounts for club memberships, while others impersonate real insurance providers like Medicare and try to collect renewal fees. It’s crucial to be familiar with your health insurance plan and recognize when scammers pitch a fake offer.<br/>‍<br/></p><h4 class="heading-19"><strong class="h4-2">Google impersonator scams</strong></h4><p class="pcr-paragraph">Certain scam calls are more specific to businesses, like calls from Google representative impersonators claiming that your company’s page is about to be removed from the search engine or Google Maps. If you get a call like this that asks for sensitive information, hang up and contact Google at a verifiable number.<br/>‍<br/></p><div class="rd-blue-radius-top-left-bottom-right"><div class="rd-blue-content-wrapper"><p class="oval-blue-rd-title">Eliminate 99% of spam calls with Robokiller</p><a id="show-call-diagram-trigger" href="https://app.robokiller.com/plans" class="dark-blue-btn contact green-gradient-button w-inline-block"><div class="white-bold-18 dark-blue">Learn more</div></a></div></div><h3 class="heading-19"><strong>Spoofed calls</strong></h3><p class="pcr-paragraph">Spammers use a tactic called Caller ID spoofing to make their phone numbers look similar to yours (like by using <a href="https://www.robokiller.com/blog/local-call" class="link-130"><strong>the same area code</strong></a>) or come up as a legitimate company.
