National Do Not Call Registry

There is both a state and federal Do Not Call Registry. Colorado residents wishing to decrease the number of telemarketing calls they receive are encouraged to register with both services.

Consumers may register with the federal registry online at The National Do Not Call Registry or by calling toll-free, 1-888-382-1222 (TTY 1-866-290-4236), from the number that is to be registered. Registration is free.

Registering with the Colorado No Call List may be done online at The Colorado No-Call List or by calling 303-776-2678 or 800-309-7041.

Numbers are downloaded from the National Do Not Call Registry on a quarterly basis and included in the Colorado No-Call List. While it is not necessary to register on both lists, the Public Utilities Commission recommends that consumers do so.

The Federal Trade Commission, the Federal Communications Commission, and the states enforce the National Do Not Call Registry. Placing a number on the registry will stop most, but not all, telemarketing calls.

The National Do Not Call Registry website has information for consumers, as well as information for telemarketers about their responsibilities related to the Telemarketing Sales Rule.

On June 17, 2008, the Federal Communications Commission amended Telephone Consumer Protection Act rules to require telemarketers to honor registrations on the national Do-Not-Call list indefinitely, so that registrations will no longer expire after five years. Under the revised rules, numbers will remain on the national do-not-call list unless the consumer removes his or her number or discontinues service. Consumers will no longer need to re-register their numbers on the national do-not-call list every five years.
