The law that created the No-Call List specifies that "persons or entities" that want to make residential, wireless, or fax telephone number(s) solicitations to Colorado residents must register and pay an annual fee to the Agent designated by the Public Utilities Commission to administer the program. Registration is required even if your company intends to use a list service (sometimes referred to as a "conforming list broker") that purports to comply with the Colorado No Call List.

Telemarketer registration fees are established and approved by the Public Utilities Commission annually. Fees paid are for the time period of January 1 to December 31. Invoices will be mailed or e-mailed to past registered telemarketers in December of each year. After fees are paid electronically, registered telemarketers will have access to the No-Call List for the year 2025. The Colorado No-Call List is updated and posted quarterly.

New 2025 Telemarketers
Because registration fees are annual fees, new telemarketers that register during the 2025 calendar year will be required to pay the full annual registration fee. New fees are set by the Public Utilities Commission during the last quarter of the year for the following calendar year. Colorado state law allows registration fees to range from $0 to $500 depending on how many employees work for a company that employs telemarketers. Click here to see the 2025 Fees. Nonprofit organizations and "conforming list brokers" may register and receive the No-Call List at no cost. Telemarketers paying by check will have access to the No Call list upon payment to Data Protection Group, LLC.

The list is updated four times a year. Once the annual registration fee is paid, telemarketers will have access to an updated list on January 10, April 10, July 10, and October 10. The updated lists must be used by January 31, April 30, July 31, and October 31.

Quarterly Updates

Proper subscription under the No-Call Act enables telephone solicitors to receive information quarterly on residential, wireless, or fax telephone number(s) subscribers who do not want to receive solicitations.
