Is this debt collector legitimate? The Colorado checks

First, the Colorado nuance: who has to be licensed at all

Colorado requires a collection agency to hold a license: Section 5-16-118 of the Colorado Fair Debt Collection Practices Act says “Any person acting as a collection agency must possess a valid license issued by the administrator in accordance with this article 16 and any rules adopted pursuant thereto.” Debt buyers are included. But three kinds of lawful collector can be absent from the register:

• An attorney. An attorney who regularly collects debts in Colorado is a collection agency under the act, but the law says such a person “shall be exempt from provisions of this article 16 that concern licensing and licensees”.
• The company you owe. A collection agency does not include “Any officer or employee of a creditor while, in the name of the creditor, collecting debts for such creditor”.
• A collector of business debts. The act covers consumer debts only: “‘Debt’ does not include a debt for business, investment, commercial, or agricultural purposes or a debt incurred by a business.”

So in Colorado, a missing license is not by itself evidence of anything. The useful move is to ask the company which of these it relies on, rather than to conclude from silence. A collection agency collecting consumer debts, a debt buyer collecting debts it has bought included, with no license and no exemption it can name, has a question to answer.

Check 1: is it on the state’s register?

The Colorado Department of Law publishes its collection agency licenses in its public license reports; search the company’s legal name. Licenses that are no longer Active stay on the record with the register’s own word for their status, and some changes of ownership need a new license, so one company can have several license numbers. The one that matters is recorded as Active; a license shown as Expired since the last July 1 may still be in force while a submitted renewal is decided, so in that case ask the Department whether a renewal is pending. Our step-by-step guide covers the traps, including legal names that differ from trading names and what each status word means. Our Colorado directory is built from this register, and ranks only agencies whose license it records as Active.

Check 2: does the first letter carry Colorado’s two statements?

Colorado gives you a check that costs nothing: the paperwork. Section 5-16-105 says that in its first written communication to a consumer a collection agency must include a statement pointing to the Attorney General’s page on the Colorado Fair Debt Collection Practices Act, and this one, word for word: “A consumer has the right to request in writing that a debt collector or collection agency cease further communication with the consumer. A written request to cease communication will not prohibit the debt collector or collection agency from taking any other action authorized by law to collect the debt.” If either statement is on the back of the letter, the front must say so.

Until July 1, 2028, the first letter must also say that “Colorado law prohibits credit bureaus from reporting medical debt or factoring medical debt into a credit score”, except for very large credit transactions. A collection agency’s first letter without these statements is not doing what the law requires, and that is a reason to ask questions before you pay anything. The Attorney General’s collection agency page is the address the statement points to.

Check 3: what does its complaint record look like?

The CFPB’s Consumer Complaint Database is free, public and searchable, and it records complaints against collectors along with how the company responded. Read it in context: the CFPB says its database is not a statistical sample of consumers’ experiences in the marketplace. A complaint is a consumer’s account, not a finding against the company. What the record is good for: does the company exist, does it respond, and are there patterns. Where we have matched an agency to the CFPB’s records, its profile here shows the all-time debt-collection complaint count, linked to the live CFPB search for that exact company name, so you can read the underlying complaints yourself.

Check 4: has a regulator formally acted against it?

Regulators publish their enforcement actions: the CFPB’s enforcement actions page lists its actions, consent orders among them, and gives each matter a status, so it also covers matters still in litigation or under appeal. In Colorado the Department of Law can issue letters of admonition, deny, suspend or revoke a license, place a licensee on probation or impose fines, and its own order is the document to read. A concluded action is a public record of what the regulator did, and it cuts both ways: it shows a regulator has dealt with the company, and it tells you something about its history. Some are consent orders, so a concluded action is not necessarily a finding of fault: read the document itself. When we have checked and published a regulator’s formal action against an agency listed in this directory, its profile carries a Public enforcement record section quoting the regulator’s own document, with the document linked, reported neutrally. It does not decide legitimacy, but it belongs in the picture, which is why we publish it.

The CFPB’s warning signs of a debt collection scam

The CFPB’s guidance starts with what a real collector will do: “A legitimate debt collector can tell you their company name and mailing address, as well as information about the debt they say you owe.” It says a collector should give you their name, the company name, its street address, a telephone number, and a professional license number if the state licenses collectors.

These are the five warning signs it lists, in its own words:

• “The debt collector threatens you or calls you late at night or at work.”
• “The debt collector refuses to give you a mailing address or phone number.”
• “The debt collector refuses to give you information about your debt or is trying to collect a debt you don’t recognize.”
• “The debt collector threatens you with criminal charges.”
• “The debt collector asks you for your personal financial information.”

CFPB: How do I tell if a debt collector is legitimate or a scam?, quoted November 5, 2026.

Two Colorado points sit alongside that list, and they are ours rather than the CFPB’s. First, the CFPB mentions a professional license number where a state licenses collectors. Colorado does, and a licensed collection agency can give you its number to check on the Department of Law’s register. Second, an attorney, or the company you originally owed collecting in its own name, may lawfully have no Colorado collection agency license, so if it has none, the useful question is which exemption it relies on.
