One of the most common questions Colorado firearm owners ask is:
“How do I register my gun in Colorado?” or “How do you register a firearm in Colorado?”

The answer is straightforward: you don’t — Colorado does not require or allow firearm registration.

Colorado law actually prohibits any system requiring lawful firearm owners to register their firearms with the state or local government. In this article, we’ll explain what the statute says, why people confuse background checks with registration, and what you actually need to know to stay compliant.

Colorado Does Not Require Firearm Registration

Colorado law explicitly prohibits the creation of a firearm registry.

Under CRS § 29-11.7-102, local governments are preempted from regulating firearms beyond state law, and the statute clearly bars any system of registration:

“No municipality, county, or city and county shall enact any ordinance or regulation requiring the registration of firearms.”

This means:

• There is no statewide firearm registry
• Cities and counties cannot create their own registries
• Law enforcement cannot require you to register a lawfully owned firearm

If you legally purchase or possess a firearm in Colorado, there is no requirement to file paperwork with the state simply to own it.

Can You Register a Gun in Colorado?

No. There is no process to register a firearm in Colorado because the law prohibits registration systems altogether.

People often search for how to register their gun in Colorado expecting a form, database, or government filing requirement. None exists. If you legally own a firearm in Colorado, there is nothing you must submit or record with the state.

Why People Think Colorado Has Registration

Many people confuse Colorado’s background check system with registration. They are not the same thing.

A registration system tracks specific firearms tied to specific owners in a centralized database. Colorado does not do this.

A background check system, on the other hand, simply verifies eligibility at the time of transfer.

In Colorado:

• Background checks are conducted through the Colorado Bureau of Investigation (CBI)
• The check determines eligibility at that moment in time
• It does not create a registry of firearms or owners

Law enforcement databases typically return whether a firearm is stolen — not whether it was registered or who currently owns it.

Universal Background Checks Are Required in Colorado

Although Colorado does not require registration, it does require background checks for most firearm transfers.

Under CRS § 18-12-112, nearly all private transfers must go through a Federal Firearms Licensee (FFL). This includes:

• Private sales
• Many person-to-person transfers
• Some loans exceeding statutory limits

The process generally requires:

1. Meeting at an FFL
2. Completing ATF Form 4473
3. Passing a CBI background check
4. Paying applicable transfer fees

Important Exceptions to Background Check Requirements

CRS § 18-12-112 includes several exceptions where a background check is not required, such as:

• Immediate family transfers
• Temporary loans for lawful purposes
• Certain emergency self-defense situations

Even in these cases, no registration requirement exists.

Does the Government Know What Firearms You Own?

Generally, no.

If you purchased through an FFL:

• The ATF Form 4473 is retained by the dealer
• It is not stored in a Colorado registry
• Law enforcement cannot simply “look up” what firearms you own

If a firearm is recovered during an investigation, law enforcement may conduct a trace through the manufacturer and distributor to the original retail purchaser. That process is investigative — not registration.

Bottom Line

Colorado does not require firearm registration. The law prohibits it.

What Colorado does require is universal background checks for most transfers — a system designed to regulate eligibility, not ownership tracking.

Understanding the difference matters. Many myths about Colorado firearm law come from confusing the two.
