What Are Robocalls and Spam Calls?

In 2022 alone, a staggering 50.3 billion robocalls inundated U.S. consumers. These robocalls, often stemming from the term “robotic call,” are phone calls initiated by computerized autodialers. Once answered, these autodialers either play a prerecorded message or connect to a human operator.

Some robocalls go a step further, utilizing personalized audio messages to create the illusion of a genuine conversation, even addressing recipients by name. While undoubtedly bothersome, these spam calls transcend mere annoyance, posing significant inconveniences and, in some instances, a genuine security risk.

What Are Different Types of Spam Calls or Robocalls

The average loss from scam phone calls was $567.41 in 2021, a significant rise from the average loss of $182 in the previous year. These staggeringly high stats derive from multiple types of spam calls. A few of these are:

1. Spoofing Calls

Spoofing calls, frequently used to coerce recipients into answering, entail the misleading alteration of caller I.D. information. This makes it seem like the call is coming from a reliable source.

2. Loan Scams

Loan scams present fictitious loan prospects that demand upfront payments or personal information. This later leaves victims with losses in money but no loan.

3. Customer Care Scams

These scams trick people into disclosing private information or making illegal payments by pretending to be customer care employees.

4. IRS Scams

IRS scams use the threat of facing legal repercussions to demand urgent cash or personal information while posing as tax officials.

5. Travel Scams

Travel scams lure victims in with alluring offers or getaways. This is only to trick them by providing inferior or nonexistent travel arrangements.

6. Charity Scams

False charity calls take advantage of kindness by requesting donations for fictitious or nonexistent causes and stealing money from legitimate charities.

Are Robocalls Illegal?

Robocalls, or automated sales calls, are illegal unless a business has your express written agreement to contact you in this way. The business cannot make using robocalls a requirement for their product or service to obtain your consent.

Instead, it must be open and honest about its intention to do so. You still have the option to withdraw your consent after giving it.

Robocalls made with the intent to deceive or commit fraud are prohibited anywhere. The U.S. passed the Telephone Robocall Abuse Criminal Enforcement and Deterrence Act (TRACED) in January 2020, giving the Federal Trade Commission new power to thwart robocalls.

By potentially boosting the maximum fee for each fraudulent call from $1,500 to $10,000, this law significantly boosts the penalties for robocall scams.
