Colorado Do Not Call List: How to Register, Block Telemarketers, and Report Unwanted Calls

The Colorado Do Not Call List was established to help residents reduce the number of unsolicited telemarketing calls, especially those from aggressive sales campaigns and fraudulent robocallers.

It is a state-administered extension of the National Do Not Call Registry, allowing Colorado consumers to protect their privacy more effectively.

Purpose of the program:

Limit intrusive telemarketing calls.
Empower consumers to manage their communication preferences.
Prevent scam calls and fraudulent sales tactics.
Support enforcement actions against telemarketers who break the law.

According to the Colorado Public Utilities Commission (PUC), millions of residents receive unwanted calls each year. Many of these originate from out-of-state or international scam operations. By registering on both the Colorado Do Not Call List and the National Registry, you can significantly reduce these interruptions.

Understanding the Colorado No-Call Law

Colorado’s No-Call Law (C.R.S. § 6-1-901 et seq.) prohibits telemarketers from calling individuals whose numbers appear on the official Do Not Call list.

The law applies to both residential and mobile phone numbers and is enforced jointly by the Colorado Attorney General’s Office and the Federal Trade Commission (FTC).

Violations can lead to fines of up to $2,000 per incident, and repeated offenses may result in criminal charges.

Key features of the Colorado No-Call Law include:

Protection against sales and marketing calls.
Coverage for landline and cell numbers.
Exemptions for certain entities (listed below).
The right to file complaints for violations.

For details, visit the Colorado PUC No-Call Program.

How the Colorado Do Not Call List Works

When you register your phone number:

Your number is added to a secure database used by registered telemarketers.
Telemarketers are legally obligated to remove your number from their call lists within 31 days.
Your registration remains active indefinitely — you don’t need to renew it.

“The Colorado No-Call program empowers consumers to say no to unwanted calls and hold violators accountable.” — Colorado Attorney General’s Office

Your number stays protected indefinitely.
You may still receive calls from exempt organizations, including:
- Charities
- Political campaigns
- Survey companies
- Businesses you’ve recently interacted with

If you continue to receive calls after 31 days, the telemarketer may be violating Colorado’s No-Call Law.

Exemptions Under Colorado’s No-Call Law

Not all calls are illegal. Certain organizations are exempt due to free speech or existing relationships.

Exempt parties include:

Charitable organizations
Political candidates and pollsters
Telephone carriers and utilities
Companies with an existing business relationship
Debt collectors operating under the Fair Debt Collection Practices Act (FDCPA)

However, even exempt callers must comply with federal robocall restrictions and avoid calling outside permitted hours (8 a.m. – 9 p.m.).

How to Report Violations

If you continue receiving unwanted calls after registration, report the incident immediately.

How to File a Complaint

Visit the Colorado No-Call Complaint Form.
Provide:
- Your phone number
- Date and time of the call
- Caller’s phone number and name (if available)
- Description of the call or message
Submit the form electronically.

You can also report violations through the FTC Complaint Assistant at ReportFraud.ftc.gov.

The Colorado Attorney General’s Office investigates complaints and may pursue civil penalties or lawsuits against violators.

The Role of the National Do Not Call Registry

The Colorado Do Not Call List works in tandem with the National Do Not Call Registry, managed by the Federal Trade Commission (FTC).

Feature	Colorado List	National Registry
Jurisdiction	State-level enforcement	Nationwide coverage
Managed By	Colorado PUC	Federal Trade Commission
Violations Fine	Up to $2,000 per call	Up to $43,792 per call
Registration Duration	Permanent	Permanent

Registering for both lists maximizes protection and legal recourse.

Why You Might Still Get Telemarketing Calls

Even after registering, some calls might continue due to:

Data brokers reselling your number.
International robocallers operating outside U.S. jurisdiction.
Spoofed numbers designed to evade blocking systems.
Existing relationships with businesses you’ve recently contacted.

To mitigate these risks, combine your registration with privacy protection services such as Remove Online Information to prevent data exposure that fuels spam call lists.

The Connection Between Data Brokers and Unwanted Calls

Telemarketers often purchase call lists from data brokers and people search websites that compile your name, number, and address from public records.

Sites like PeopleWhiz, Spokeo, and Radaris collect and sell this information legally under current U.S. privacy laws.

To stop these calls permanently, you must:

Opt out of these data broker websites.
Request removal of your personal information.
Monitor for reappearances using professional services.

Remove Online Information specializes in these removals, helping ensure your contact data isn’t used for telemarketing or solicitation.

How Remove Online Information Helps

Even with the Colorado Do Not Call List, your number may still be visible across multiple public data directories.

Remove Online Information provides:

Comprehensive data removal from hundreds of broker and background sites.
Reappearance monitoring to keep your number private long-term.
Search engine suppression to remove cached and indexed personal data.
Custom privacy plans for individuals, families, and businesses.

By combining official registration with expert data removal, you can dramatically reduce unwanted calls and protect your privacy.

Additional Tips to Block Telemarketers

Use call-blocking apps: Tools like Hiya, Nomorobo, or Truecaller help identify and block spam numbers.
Don’t engage: Responding or pressing buttons during robocalls confirms your number is active.
Avoid sharing your phone number publicly: Remove it from social media profiles and public listings.
Enable carrier spam filters: Most mobile providers (AT&T, Verizon, T-Mobile) offer free anti-spam protection.
