KNOW BEFORE YOU BUY

Local Colorado regulations

Colorado has specific telemarketing laws that businesses must comply with to avoid penalties.

Commercial telephone sellers must register with the Colorado Attorney General at least ten days before conducting business in the state, paying an initial $200 registration fee; annual renewal requires a $100 processing fee and a completed renewal form.
Telemarketers must comply with Colorado's No-Call List Act, which requires a tiered annual registration fee to access the database of telephone numbers administered by the Public Utilities Commission; persons or entities with fewer than five employees may qualify for fee exemptions.
Consumers may seek damages of up to $2,000 per unlawful call in court for violations of Colorado's telemarketing laws, and the Attorney General may pursue additional enforcement actions under the Colorado Consumer Protection Act, as outlined by C.R.S. §6-1-301.

These regulations emphasize the need for businesses to adhere to state-specific rules when engaging in telemarketing within Colorado.
