Stop Spam Telephone Calls Information Guide

Understanding Spam Telephone Calls and Why They Happen

Spam telephone calls are unwanted calls from telemarketers, scammers, robocalls, and other sources trying to sell you something, collect information, or commit fraud. The Federal Communications Commission (FCC) reports that Americans received approximately 3.7 billion robocalls in 2023, with call volumes remaining high in subsequent years. These calls range from annoying sales pitches to serious scams that attempt to steal money or personal information.

Spam calls happen because contact lists are valuable. Scammers and telemarketers purchase or steal phone numbers from various sources. Sometimes your number ends up on these lists simply because you answered a call from an unknown number—this confirms to scammers that your phone is active. Other times, data breaches expose millions of phone numbers at once. Companies also sell contact information legally (though there are restrictions), and your number may be on these commercial lists.

The technology behind spam calls has become more sophisticated. Callers use Voice over Internet Protocol (VoIP) services to make calls cheaply from anywhere in the world. They can spoof caller ID information, making it appear that a call is coming from your own area code or from a trusted organization like your bank or the government. This makes it harder to identify legitimate calls from scams.

Understanding how spam calls work is the first step in protecting yourself. Scammers succeed because they rely on confusion and trust. By learning about common tactics and warning signs, you can recognize spam calls before they affect you.

Practical Takeaway: Spam calls are widespread and use technology to seem legitimate. Being aware that these calls are designed to deceive helps you stay cautious when answering unknown numbers.

Common Types of Spam and Scam Calls

Several categories of unwanted calls target consumers regularly. Recognizing the type of call you receive helps you respond appropriately. The following are the most common types.

Robocalls: These are automated calls using recorded messages. Legitimate robocalls include appointment reminders from doctors' offices or delivery notifications from retailers you do business with. However, illegal robocalls try to sell you things (like credit card offers or extended vehicle warranties) or gather information. The Telephone Consumer Protection Act (TCPA) restricts robocalls, but violations are common.

Tech Support Scams: Callers claim your computer has a virus or security problem and try to convince you to let them access your device remotely. Once they gain access, they may install malware, steal passwords, or demand payment for fake repairs. These calls often use urgent language and may include pop-ups on your device during the call to make the threat seem real.

IRS and Government Impersonation Scams: Callers pretend to be from the IRS, Social Security Administration, or other government agencies claiming you owe money or your benefits will be stopped. They demand immediate payment via gift cards, wire transfers, or cryptocurrency. The real IRS initiates contact through mail first, never by phone for first contact about a debt.

Grandparent Scams: Callers pose as a grandchild claiming to be in urgent trouble (arrested, in an accident, or stranded abroad) and begging for money sent immediately. These scams prey on emotional responses and use time pressure to prevent victims from verifying the story.

Prize and Lottery Scams: You receive a call saying you have won a contest or lottery you never entered. To claim your prize, you must pay taxes or processing fees upfront. Legitimate lotteries never require payment to claim winnings.

Credit Card and Banking Scams: Callers claim to be from your bank or credit card company saying fraudulent activity was detected on your account. They ask you to verify your account number, PIN, or other sensitive information. Banks never request this information by phone.

Practical Takeaway: Learn to recognize common scam types by their characteristics: urgency, requests for money or personal information, and claims you didn't expect. If a call matches these patterns, treat it as suspicious regardless of who the caller claims to be.

How to Identify Spam Calls Before Answering

You can take steps to identify spam before you pick up the phone. Modern smartphones and phone services provide tools to help screen calls. Learning to recognize patterns in spam calls also helps you decide whether to answer.

Caller ID and Number Analysis: Pay attention to caller ID information. Scammers often spoof numbers that appear local to you or that look like they come from trusted organizations. If a number seems familiar but slightly off, or if the caller ID says something like "Unknown Caller" or "Blocked," treat it with caution. Numbers that skip area codes or use unusual digit patterns may also be suspicious. However, remember that caller ID spoofing is common, so even numbers that appear legitimate could be fake.

Time of Call: Spam calls often come at odd hours or in patterns. If you receive multiple calls from different numbers in a short period, or if calls come very early or very late, they are likely spam. Legitimate organizations typically contact you during business hours and respect Do Not Call preferences.

Call Filtering Services: Most phone carriers offer free or low-cost call filtering through their networks. Verizon offers Call Filter, AT&T offers Call Protect, and T-Mobile offers Scam Shield. These services identify known spam numbers and block or label them before they reach you. Third-party apps like RoboKiller, Nomorobo, and Truecaller also analyze incoming calls and flag suspected spam.

Silence or Automated Greeting: Many spam calls begin with silence, a brief pause, or an automated message before connecting to a live person. This happens because the calling system dials many numbers at once and connects calls to available agents only when someone answers. If you hear this pattern, it is almost certainly spam.

Practical Takeaway: Use your phone's built-in call filtering and consider additional apps. Review incoming calls before answering, and be especially cautious of calls from unfamiliar numbers, spoofed local numbers, and calls with automated elements.

Actions to Take When You Receive a Spam Call

How you respond to a spam call matters for your safety and to help reduce future calls. Taking appropriate action protects you and provides information that helps authorities track illegal callers.

Do Not Provide Personal Information: Never give out your Social Security number, bank account information, credit card numbers, PINs, passwords, or other sensitive details in response to an unsolicited call. This is the most important rule. Legitimate companies and government agencies already have your information if they need to contact you, and they will never ask for sensitive details by phone. If you are unsure, hang up and contact the organization directly using a phone number you find independently (not one provided by the caller).

Do Not Confirm Your Number or Personal Details: If a caller asks, "Is this [your name]?" or "Can you confirm your phone number?", do not confirm. This tells the scammer they have reached a real person and a valid number. Instead, ask who is calling and why, and verify the call independently before providing any information.

Hang Up Immediately: You do not owe the caller a conversation. If you suspect spam or feel uncomfortable, hang up. Do not listen to the entire message, and do not press numbers to be removed from a call list (this often confirms your number is active and may result in more calls). For robocalls, hanging up is the fastest response.

Do Not Call Back Unknown Numbers: Scammers sometimes use callback scams, leaving voicemails with brief messages designed to prompt return calls. If you call back, you may reach an automated system that charges you money or connects you to a scammer. If you do not recognize the number, do not call it back.

Report the Call: Report spam calls to the FCC at ReportSpam.gov or by forwarding the message to 7726 (SPAM) using your cell phone. You can also file a complaint with the Federal Trade Commission (FTC) at ReportFraud.ftc.gov. If the call involved impersonation of a
