Colorado PTFA Cell-Number Directory Litigation

Understanding the trend

What is this trend?

This report maps 28 filed cases, five active plaintiff-firm investigation targets, and 86 Forecasts tied to allegations that Colorado residents' cellular numbers were listed in commercial directories without affirmative consent. Plaintiffs are testing the Colorado Prevention of Telemarketing Fraud Act listing provision as a privacy class-action theory against data brokers, people-search platforms, B2B contact vendors, credit/data bureaus, and real-estate lead tools. The case pattern begins in 2025 and accelerates in 2026, with Colorado filings joined by outbound venue filings in California, Massachusetts, Florida, Illinois, Washington, New York, and federal Colorado. The current draft adds Crexi Intelligence and Demandbase to the investigation view and broadens the Forecasts to companies whose products or public descriptions warrant monitoring under the same pleaded theory.

What caused it

Public defense commentary continues to frame the listing provision as novel and under-tested. External commentary is used for legal posture and market context; the report separates filed litigation, plaintiff-firm investigation pages, and Forecasts.

Practices driving the lawsuits

• Real-estate lead-generation and people-search products are a recurring part of the current plaintiff-side fact pattern.
• The statute remains early-stage and contested, so defenses around directory status, commercial purpose, consent, standing, and class membership remain central.
• Forecasts remain concentrated in data broker, people-search, contact intelligence, and real-estate lead-list products that monetize direct-dial or mobile-number access.
