Who's Blowing Up Your Phone in 2024? CallBuster's Robocall Data Breaks It Down by Industry

If it feels like your phone has become a magnet for junk calls lately, you're not imagining it. Based on CallBuster's analysis of user-reported spam calls across our platform throughout 2024, robocall volume has continued its stubborn upward trajectory — and the industries behind those calls have shifted in ways worth paying attention to.

We dug into the data so you don't have to. Here's what we found about who's targeting American consumers this year, where they're hitting hardest, and — most importantly — how to shut them down.

The Overall Picture: More Calls, Smarter Tactics

Total spam call volume reported through CallBuster in 2024 is tracking roughly 11% higher than the same period in 2023. That's not the most alarming part. What stands out is that the quality of spam calls — meaning how convincing and targeted they've become — has measurably improved. User reports flagging calls as "highly convincing" or "almost fell for it" are up nearly 30% year over year.

Scammers are getting better. The silver lining? So are we — and so are the patterns that make them identifiable.

Industry Breakdown: The Biggest Offenders of 2024

1. Healthcare & Health Insurance — The #1 Offender

For the second consecutive year, healthcare-related spam tops our charts. This category — which includes fake Medicare alerts, bogus prescription discount programs, phony health insurance enrollment calls, and fraudulent medical equipment offers — accounts for approximately 34% of all spam calls reported in our network.

The surge makes sense when you consider context: ongoing confusion around ACA marketplace plans, the post-pandemic expansion of telehealth, and the massive senior population that scammers specifically target. Calls in this category tend to spike dramatically in October through December, coinciding with Medicare's Open Enrollment Period. If you've got elderly relatives, this is the window to make sure they have call protection active.

Best blocking strategy: Enable CallBuster's "Healthcare Spoofing" filter, which cross-references caller ID data against known Medicare and insurance scam number clusters. Legitimate insurers will always provide written communication as a follow-up — if a call is your only notice, treat it as suspicious.

2. Financial Services & Debt Relief — The Pressure Specialists

Coming in at around 22% of reported spam, financial services calls are the most psychologically aggressive category in our dataset. This bucket includes fake IRS threats, credit card interest reduction scams, student loan forgiveness pitches (which spiked following ongoing federal loan policy news), and debt consolidation traps.

What makes this category particularly effective is urgency. These calls are scripted to create immediate panic — "your account will be suspended," "a warrant has been issued" — and push victims into acting before they think. Our data shows calls in this category are most common on Monday mornings and Friday afternoons, timing designed to catch people either starting a stressful work week or distracted heading into the weekend.

Geographically, our data shows higher-than-average concentrations of financial spam calls hitting users in Florida, Texas, and Nevada — states with large retirement communities and high rates of financial vulnerability among older residents.

Best blocking strategy: Any call claiming to be the IRS, Social Security Administration, or a debt collector threatening legal action should be immediately reported and blocked. These agencies do not initiate contact by phone for urgent matters. Period.

3. Home Services & Utilities — The "We're Already Working in Your Area" Scam

This one has grown fast. Home services and utility-related spam now represents about 18% of our reported call volume, up from 12% in 2022. The pitch is almost always some variation of: "We're doing work in your neighborhood and noticed your [solar panels / HVAC system / roof] may qualify for a free inspection or rebate."

Utility impersonation calls — where scammers pretend to be your electric or gas company threatening disconnection — are especially prevalent in the South and Midwest, where extreme weather seasons create natural anxiety around utility reliability.

Summer months see a predictable spike in solar and energy efficiency scam calls, while winter drives up fake heating assistance and utility shutoff threats.

Best blocking strategy: CallBuster's neighborhood-level spam mapping can show you whether a number has been flagged by other users in your zip code. If your neighbors are reporting the same "local contractor" number, it's a dead giveaway.

4. Travel & Vacation Packages — The Dream Sellers

At roughly 10% of reported calls, travel scams might seem like a smaller slice, but they punch above their weight in terms of average financial damage per victim. Free cruise offers, timeshare exit schemes, and fake vacation club memberships tend to target consumers who've recently searched for travel deals online — a sign that scammers are increasingly using data from third-party brokers to personalize their pitches.

These calls cluster heavily around major holidays and spring break season, and they disproportionately affect users in the 35–55 age bracket based on our demographic reporting.

5. Auto Warranties & Vehicle Services — The Perennial Classic

The extended auto warranty call is practically a cultural institution at this point, and it's still going strong at around 9% of our call volume. Despite years of consumer awareness campaigns, this scam persists because it works — especially on newer car owners who may genuinely be uncertain about their warranty coverage.

Best blocking strategy: This category responds exceptionally well to simple number-pattern blocking. Most auto warranty robocall campaigns rotate through recognizable number clusters. CallBuster's auto-block feature catches the majority of these before they ring through.

Emerging Threats to Watch: What's Coming Next

Beyond the established categories, our analysts have flagged a few emerging spam patterns that consumers should be on alert for heading into 2025:

• AI-generated voice scams: We're seeing early-stage reports of calls using synthetic voices that convincingly mimic local accents and even specific institutions. Expect this to accelerate.
• Package delivery scams: With e-commerce at all-time highs, fake "failed delivery" calls are rising sharply — particularly targeting users in suburban zip codes.
• Political and charity solicitation fraud: An election hangover effect is pushing a wave of fake political fundraising and disaster relief charity calls. These are harder to block because they often use legitimate-looking nonprofit spoofing.

What You Can Actually Do About It

Data is only useful if it changes behavior. Here's the practical takeaway from everything above:

1. Layer your defenses. Carrier-level blocking (like AT&T ActiveArmor or Verizon Call Filter) catches some calls, but it misses plenty. A dedicated app like CallBuster adds a second filter that updates in real time based on what our user community is actually reporting.
2. Customize your block lists by category. You can tune CallBuster's filters to be more aggressive in the categories that statistically affect your demographic and region most.
3. Report every suspicious call. Your reports directly improve the accuracy of our spam detection for every other user on the platform. It takes 10 seconds and it genuinely matters.
4. Educate the people in your life who are most at risk. Our data consistently shows that adults over 65 bear a disproportionate share of successful scam contacts. Share this breakdown with your family.

The robocall industry is adaptive, well-funded, and motivated by billions of dollars in potential fraud revenue. But it's also pattern-based — and patterns can be identified, tracked, and blocked. That's exactly what we're here for.
