Is the Colorado Do Not Call registry free?

Consumer registration is free in every state. Telemarketers may pay a fee to access the list for compliance scrubbing. You never pay to add your number.

Does the Colorado DNC list cover cell phones?

Yes. Cell phones are covered. The federal registry has accepted cell phone numbers since inception. The Colorado state list also covers mobile numbers. You can register any personal number — landline or wireless — to block telemarketing calls.

Does it cover text messages?

Telemarketing text messages are restricted under the TCPA whether or not your number is on the DNC list. Registration on the DNC list adds an additional layer of liability for any telemarketer who texts you.

What is the penalty for calling a registered Colorado number?

Federal TCPA: $500 per call ($1,500 willful). FTC TSR penalties up to $51,744 per call. Colorado state penalty: $2,000 per call — and you can sue the telemarketer directly under the state private right of action.

What do I do when telemarketers call after I registered?

Three steps. (1) Tell the caller to put you on their internal do-not-call list — that triggers a separate 30-day cure obligation. (2) File a complaint at donotcall.gov. (3) Document the call (date, time, number, company, what was offered). In Colorado you have a private right of action — you can sue the telemarketer in small claims or state court.

Is registration permanent?

Yes. Federal registration is permanent — once your number is on the list, it stays until you remove it or disconnect the line. Colorado state registration is also permanent.

Colorado Do Not Call Registry

How to register, what it covers, and how to enforce — 2026

Colorado runs its own DNC registry

Colorado maintains its own Do Not Call list separate from the federal National DNC Registry. Consumers should register on both lists for full protection.

Telemarketers calling into Colorado must scrub their lists against the state registry AND the federal registry before each campaign. Scrubbing only the federal list is not enough.

Federal National DNC Registry

donotcall.gov

Administered by the Federal Trade Commission. Free, permanent, covers landlines and cell phones in every state.

How long it takes effect

Federal: 31 days for telemarketers to scrub against your number. State registries vary — most align with the federal 31-day window. Reputable telemarketers stop calling within a week. Bad actors keep calling and rack up violations.

What the registry covers

Landlines

Yes

Cell phones

Yes

Text messages

Restricted under TCPA

What it blocks: Telemarketing sales calls and texts. Calls trying to sell you something.

What it does NOT block: Political calls, charitable solicitations, calls from companies you have a current business relationship with (within 18 months of last purchase / 3 months of inquiry), debt collectors, surveys, and informational calls.

Robocalls and AI voice: Already restricted by TCPA regardless of registration. Adding your number to the DNC list adds an extra layer of liability for callers.

Consumer registrationPermanent

Governing statuteC.R.S. § 6-1-901 et seq.

Colorado maintains a SEPARATE state No-Call List administered by the PUC through its designated agent, Data Protection Group LLC. Over 2.7 million Coloradans are registered. Telemarketers face a DUAL registration requirement: (1) Register with the Colorado AG ($200 initial, $100 annual renewal) and (2) Register with the Colorado No-Call program via ColoradoNoCall.com. No-Call List registration fees are annual, based on total company employee count, ranging from $0 to $500. Penalties include actual damages, statutory damages up to $500 per violation, and attorney fees. Consumers register for free online at ColoradoNoCall.com or by calling 303-776-2678 / 800-309-7041. Must scrub against BOTH the state list and the federal NDNC.

What to do when telemarketers call after you registered

Tell the caller to put you on their internal do-not-call list. That triggers a separate 30-day cure obligation under federal law. If they call again after 30 days, that is an independent violation.
File a federal complaint at donotcall.gov/report. The FTC tracks these and pursues serial offenders.
Document the call. Date, time, number that called, company name, what they were selling. Screenshot or save voicemails. This is the evidence you need if you sue or file a state complaint.
Sue the telemarketer in Colorado. Colorado has a private right of action — you can recover $2,000 per call without proving actual damages. Federal TCPA adds another $500–$1,500 per call. File a complaint here →
