DNC (Do Not Call) Registry explained
The regulatory environment around this registry tightened sharply in 2025. Monthly DNC complaint volume rose from roughly 73,000 per month in 2024 to roughly 113,000 per month in 2025, and approximately 4.8 million new numbers were added to the registry over the same period, per Corporate Compliance Insights' review of 2025 telemarketing compliance. That data covers general telemarketing enforcement, not solar specifically, but it describes the environment every solar caller is operating inside.
Solar-specific enforcement backs up that general trend. Momentum Solar reached a $20 million to $30 million TCPA class-action settlement, with final approval in August 2025, and separately, the FCC removed more than 1,200 voice service providers from the Robocall Mitigation Database in August 2025 for deficient filings, cutting off their network access entirely. Regulators are actively enforcing in exactly this category, not just watching it.
Given the volume and enforcement trend, DNC scrubbing has to be a documented, real-time, verifiable step in any outbound program, not an assumption baked into a script and left unaudited.
Why it matters when you're buying
Ask any vendor calling on your behalf, in-house team or outsourced, exactly how and how often they scrub against the DNC registry. The complaint-volume trend suggests enforcement risk is rising, not stable, and "we check the list" is not the same answer as a documented, auditable process.
