Mini-TCPA State — C.R.S. § 6-1-901 et seq.; C.R.S. § 6-1-301 et seq.

Colorado has enacted a state-level TCPA that goes beyond federal requirements. Federal compliance alone is not enough for AI Voice operations here.

Colorado is one of the first states with a dedicated AI Act (effective 2026). AI voice calls require prior express written consent AND disclosure that the consumer is interacting with an AI system. The combination of the Telephone Consumer Protection Act and the AI Act makes Colorado one of the strictest states for AI voice outreach.
