You might not have noticed, but the Do Not Call list is quietly working really well.
Enigma crunched the latest Federal Trade Commission data and found that while the Do Not Call list has grown to include about 250 million numbers, Do-Not-Call complaints have plummeted.
The drop off is stark: Americans lodged 5 million Do-Not-Call complaints in fiscal year 2021 and that number has now fallen to 1.5 million in fiscal year 2025.
Big dialers have been squeezed out by tougher enforcement, and that means that the current complaint file is pure signal: if a brand (or the carrier behind it) is still showing up, something’s wrong.
That’s exactly the kind of low-noise, high-yield input that KYB teams should fold into onboarding and monitoring processes to spot risky merchants and VoIP partners long before the usual checks light up.

Enigma developed this list by taking the latest FTC dataset and normalizing and deduped the phone numbers. We then resolved each caller ID to a brand and originating carrier with our phone-to-domain lookup. Then we ranked the list by total complaints and complaints-per-unique-number to surface outsized offenders, and cross-checked the results with Reddit, ScamAdviser, BBB, FCC consent decrees, and PACER to separate fraud from harmless misdials.
What’s left are exactly the kinds of companies that should have your KYB process to weed out as early as possible.
