A Deep Dive Into the Most Annoying and Dangerous Calls in 2025
Spam calls are an unfortunate reality of modern life. Despite advancements in telecommunications regulation and call-blocking technologies, millions of people continue to receive unwanted calls every day. In 2025, spam calls are more sophisticated, more targeted, and in many cases, more dangerous than ever. In this blog post, we’ll explore the most common types of spam calls that are plaguing consumers today, and how you can protect yourself from them.
1. What Exactly Is a Spam Call?
A spam call refers to any unsolicited telephone call that attempts to sell, scam, or extract information from you. These calls are often made by telemarketers, robocallers, or fraudsters. According to the Federal Communications Commission (FCC), Americans received over 50 billion robocalls in 2023 alone, many of which were classified as spam. The most troubling trend? Scammers are increasingly using AI and spoofing techniques to disguise their real identities.

2. Scam Calls Posing as Government or Financial Institutions
Among the most dangerous spam calls are those impersonating trusted institutions like the IRS, FBI, or major banks. These calls often claim you owe back taxes or that your bank account has been compromised. Scammers use urgency and threats to manipulate victims.
Examples of common scripts include:
- “This is the IRS. You owe unpaid taxes. Failure to comply will result in legal action.”
- “Your account has been frozen due to suspicious activity. Please verify your identity now.”
According to the Federal Trade Commission (FTC), the average financial loss from government impersonation scams in 2024 was over $1,000 per victim.
3. Robocalls: Automated Nuisance at Scale
Robocalls are pre-recorded voice messages sent out by automatic dialing systems. While some robocalls are legal (such as those from political campaigns or pharmacies), many are spam or scams.
Characteristics of robocalls:
- Pre-recorded messages
- No human interaction at the beginning
- Often use caller ID spoofing to mimic local area codes
The YouMail Robocall Index tracks over 4 billion robocalls per month in the U.S. alone.

4. Cryptocurrency and Investment Scams
These spam calls promise huge returns on “safe” investments like Bitcoin or startup stocks. With crypto adoption increasing globally, scammers have capitalized on FOMO (fear of missing out) to lure victims.
Common pitches include:
- “You’ve been selected for a once-in-a-lifetime crypto opportunity!”
- “Invest $500 today and earn $5,000 in a week.”
The U.S. Securities and Exchange Commission (SEC) has repeatedly warned consumers about such scams.

5. Tech Support Scams
These calls claim your computer or mobile device is infected with a virus or has been hacked. The caller pretends to be from Microsoft, Apple, or Amazon and urges you to install remote-access software like TeamViewer.
Once installed, scammers can:
- Access personal files
- Install malware
- Steal banking information
Microsoft’s 2022 Global Tech Support Scam Survey found that 68% of consumers had encountered at least one tech support scam in the previous year.

6. “You’ve Won!” Prize and Lottery Calls
This type of call claims you’ve won a prize or sweepstake, but requires a payment to claim it — either for “processing fees” or taxes. This is a classic advance-fee scam.
Typical indicators:
- Unfamiliar sweepstakes or contests
- Urgency to respond “within 24 hours”
- Requests for payment via wire transfer or gift cards
Tip from FTC: Legitimate lotteries never ask you to pay to claim your prize.

7. “Grandparent” or Impersonation Scams
These emotionally manipulative calls often target the elderly, with scammers pretending to be a grandchild or other relative in urgent need of money. With the rise of AI-generated voice cloning, these calls have become even more convincing.
A 2023 Washington Post investigation showed how AI voice tools were being used to mimic family members in distress, making these scams harder to detect.

8. Legitimate Telemarketing Calls That Border on Spam
Not all spam calls are illegal. Many are from real businesses offering services like insurance, credit repair, or solar panels. While they may be legal under the Telemarketing Sales Rule (TSR), they’re often unwanted and relentless.
Common characteristics:
- Repetitive calls from the same provider
- Ignoring “Do Not Call” registry listings
- Aggressive sales tactics
