Connecticut adopted the federal National DNC Registry in place of its former state-specific list. Consumers previously registered on the state list are automatically protected. CRITICAL: Effective October 1, 2023, Connecticut passed SB 1058 — one of the strictest telemarketing laws in the country. It effectively PROHIBITS COLD CALLING by requiring express written consent before making telemarketing calls, even to numbers NOT on the DNC list. Within the first 10 seconds of any call, the telemarketer must identify themselves, state the purpose, and ask if the consumer wishes to continue. Penalties: up to $20,000 per violation. Permitted hours: 9am-8pm. No state telemarketer registration requirement exists, but compliance with the consent requirement is mandatory. Connecticut does NOT require a separate state registration fee.
