A Data Story · U.S. Outbound Dialing · 2015–2026

Getting Through

America's phones were buried under 58 billion robocalls a year. Then came the filters, the mandates, and the lawsuits. The noise is finally receding, and for honest callers the era of easy dial tone is over. Reaching a customer now has a price: a reputation worth answering.

The flood

A robocall costs a fraction of a cent. By the mid-2010s, cloud auto-dialers had made it possible to ring a million phones before lunch, from anywhere on earth, wearing any caller ID you liked. The American phone number, for a century a fairly reliable way to reach a person, became the cheapest attack surface in commerce.

What follows is eleven years of monthly data: every robocall placed to a U.S. phone, as estimated by the YouMail Robocall Index.

Robocalls placed to U.S. phones, monthly · Jun 2015 – May 2026
2015–2016When the index began in mid-2015, Americans were already receiving over a billion robocalls a month: 29 billion in 2016 alone. It was annoying. It was about to get much worse.
2017–2019 · the surgeCheap cloud dialing rewrote the economics of mass calling, and volume nearly doubled in two years. In 2019 it peaked at 58.5 billion calls, roughly 178 for every person in the country. October 2019 alone saw 5.66 billion.
Dec 30, 2019Washington answered. The TRACED Act passed the Senate 97–1 and was signed into law, turning caller-ID authentication from an industry suggestion into a federal mandate, with real forfeiture authority behind it.
Spring 2020Then COVID did what regulation hadn't yet: it closed the boiler rooms. April 2020 volume fell to 2.9 billion, half the peak. The calls came back, of course. But something else was coming online.
Jun 30, 2021Every major U.S. carrier was now required to implement STIR/SHAKEN: cryptographically signing calls so networks could verify who was really calling. Unsigned, unregistered traffic started dying at the network edge.
2022–2025 · the grindVolume stopped growing, and enforcement kept squeezing: gateway-provider rules, nine-figure FCC forfeitures, and in February 2024, an outright ban on AI-voice robocalls. The flood became a plateau; the plateau began to tilt.
2026And then, quietly, the tide went out. Every month of 2026 has come in near 4 billion calls, the lowest sustained level in nearly a decade. The machinery built over six years is working. The question is what it filtered out along the way.

What's in the pipe

“Robocall” was never one thing. The same technology that delivers a Medicare scam also delivers your pharmacy refill, your kid's school closing, the fraud alert that saves your checking account. The story of the last decade isn't just how much the pipe carried; it's what the mixture was.

Composition of U.S. robocall traffic · share by category, 2016–2026
2016In 2016, nearly three-quarters of robocall traffic was signal: alerts, reminders, and payment notifications people had actually asked for. Scams were 17 percent of the pipe.
2019By the peak, the mix had inverted: scams alone were 43 percent of all robocalls. The noise didn't just outnumber the signal; it taught an entire country to stop picking up the phone.
2026Today the pipe is cleaner: scams are down to roughly 20 percent, and wanted notifications are back above a third of robotraffic. The water receded. The problem is what the flood left behind: nobody trusts the phone anymore.

The complaint ledger

The FTC's Do Not Call Registry is the country's longest-running measure of phone-call resentment: 258.5 million numbers are now registered, and every complaint filed against a caller is logged and published. The ledger tells the same story from the consumer's side of the line, with one warning flag at the end.

Complaints fell 71% from the peak…

FY2025 complaints by topic, robocall + live caller
After seven straight years of decline, complaints rose 25 percent in FY2025. The “reducing debt” category alone drew 441,430 complaints, more than the next three categories combined. The filters are winning, but the adversary is still adapting. Vigilance, not victory.

The collateral damage

Here is the uncomfortable part. The filters that strangled the robocall (carrier analytics, spam labels, network-edge blocking) don't read intent. They read velocity, complaint rates, answer patterns. A clinic confirming surgeries, a bank flagging fraud, a utility warning of an outage can trip the same wires as a warranty scammer.

Americans didn't stop needing phone calls. They stopped trusting them, and the machines learned to distrust them too.

Where the noise lands

Unwanted calling isn't evenly distributed. Per capita, the complaint capital of America is Arizona, at 1,028 complaints per 100,000 residents in FY2025, with Tennessee and Nevada close behind. Hawaii files the fewest.

The new rules of getting through

For a business that depends on the outbound call (the clinic, the lender, the logistics firm, the school district) the lesson of this decade is not stop calling. The call still works; people still answer the calls they want. The lesson is that the network now keeps score, and the score is your reputation.

Authenticate everything

85% of traffic between Tier-1 carriers is now signed and verified under STIR/SHAKEN, but only 17.5% between smaller carriers. Unsigned traffic is presumed noise. Full attestation is table stakes for being treated as signal.

Treat consent like a contract

TCPA class actions roughly doubled in 2025: 224 were filed in September alone. Every number dialed without clean, current, provable consent is both a legal liability and a complaint generator that feeds the filters.

Guard reputation like infrastructure

With 1 in 4 legitimate numbers at risk of a spam label, number reputation is operational infrastructure: monitored, maintained, and remediated like uptime. A label event is an outage.

Earn the answer

Call when you said you would. Say who you are. Leave a number that picks up when called back. The callers thriving in 2026 are the ones whose calls people are glad they answered. The algorithm notices that too.

The robocall era didn't kill the phone call. It repriced it.

Reaching someone by voice now costs what it arguably always should have: being identifiable, being asked for, being worth answering. Six years of law and machinery taught the network to separate signal from noise: imperfectly, relentlessly. For the honest caller, that's not the obstacle. It's the opportunity: in a filtered world, trust is the dial tone.
