Law Enforcement National Electronic Tracing System & Share Program

The Bottom Line

Colorado is requiring every local and state law enforcement agency to plug into a federal database to track firearms used in crimes. If police confiscate a gun during an investigation, they will have to run it through this system to see where it came from. It is mostly about standardizing a practice that the vast majority of police departments are already doing behind the scenes.

What This Bill Actually Does

By September 1, 2026, this legislation requires all state and local law enforcement agencies in Colorado to formally register with eTrace. For those unfamiliar, eTrace is a massive, web-based tracking system maintained by the federal Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). While a large number of police departments already use this tool voluntarily to track where crime guns originated, this bill elevates that practice from a highly recommended standard to an absolute statewide mandate. The goal is to ensure that no police department, regardless of its size or budget, is left out of the national network that tracks illegal weapons.

Here is exactly how the mandate works on the ground: If officers recover or confiscate a firearm in connection with a criminal investigation, they are legally required to log that weapon's details—like its serial number, make, and model—into the eTrace system. The ATF then uses that data to trace the weapon's journey from its original manufacturer or importer, down to the wholesale distributor, and finally to the retail dealer who made the first legal sale. However, the bill draws a very clear, deliberate line on what does not get tracked. Police are explicitly exempt from tracking guns dropped off during a voluntary relinquishment program (such as a community gun buyback) or weapons that are found and quickly determined to have zero connection to any criminal activity.

In reality, this bill is designed to close a relatively small but critical data gap. According to research from the Joyce Foundation cited in the state's fiscal note, almost all Colorado law enforcement agencies are already enrolled in eTrace. The legislation is essentially making sure that the final few holdouts get on board, creating a uniform, airtight statewide network. This ensures data on illegally possessed firearms is shared consistently with federal authorities, making it easier to uncover underground trafficking rings or illegal sales patterns that cross city and county borders. There is also a practical exemption for smaller, rural departments: if they already access the eTrace system through a preexisting relationship with a larger neighboring agency—like a small town relying on the county sheriff's dispatch—they do not have to create redundant, standalone accounts.

What It Means for You

For the average Colorado resident, this bill is not going to change your daily routine, but it does touch directly on how your local community handles public safety and criminal investigations. If you are a legal, responsible gun owner, you can breathe easy knowing this legislation does not impose any new tracking, registries, or background checks on your legal purchases. The focus here is strictly and exclusively on firearms tangled up in active criminal investigations. If you ever need to surrender a firearm voluntarily—for example, if you inherit a relative's hunting rifle that you do not want and hand it over to the local precinct—the bill specifically exempts those voluntary relinquishments from the mandatory federal tracking process.

The broader, lasting impact for neighborhoods is about standardizing how local police fight violent crime. By forcing every jurisdiction onto the exact same federal platform, detectives have a much better shot at identifying "straw purchasers"—individuals who buy guns legally with a clean background check only to immediately sell them on the black market to criminals. When every recovered crime gun in Colorado is tracked through one central database, law enforcement can more easily map out and disrupt illegal weapon pipelines that flow between rural towns and major urban centers like Denver or Colorado Springs.

Here are the primary takeaways for your household:

• No new databases for legal owners: This mandate applies solely to guns confiscated during criminal investigations, not standard civilian ownership.
• Firm Timeline: Agencies have until September 1, 2026, to establish their accounts and train their officers.
• Local Resources Protected: Because the federal government provides this tracking software for free, your local town or county will not have to divert property tax dollars away from community patrols to pay for expensive new tech licenses.

What It Means for Your Business

If you own a standard Colorado business—whether that is a construction firm, a restaurant, a dental practice, or an IT consultancy—this bill will pass entirely under your operational radar. There are absolutely no new compliance hurdles, reporting requirements, state fees, or tax burdens for private sector businesses outside the firearms industry. You get the indirect benefit of a more unified police force tackling violent crime without having to pay a dime out of your business operations to fund it.

However, if you are a Federal Firearms Licensee (FFL) operating a gun store, pawn shop, or sporting goods retailer, this administrative change at the law enforcement level will definitely impact your back-office operations. When police run a confiscated gun through eTrace, the ATF's National Tracing Center reaches out to the original manufacturer, then the distributor, and finally to the retail dealer (you) who made the original sale. Because every single Colorado law enforcement agency will now be legally required to use this system for every crime gun, FFLs should anticipate a potential uptick in trace requests from the ATF.

What to keep in mind if you operate in the firearms or security space:

• Recordkeeping is crucial: Ensure your Bound Books (Acquisition and Disposition records) and ATF Form 4473s are meticulously organized and easily searchable. A higher volume of police departments actively tracing guns could mean quicker, more frequent inquiries if a weapon you sold legally eventually ends up at a crime scene.
• No new state mandates for dealers: The bill regulates police departments, not retail stores. You are simply responding to the standard federal trace requests you already handle, just potentially at a higher volume.
• Private Security Considerations: If you run a private security firm and your personnel are ever involved in an incident where a weapon is confiscated by police as part of an official investigation, expect that firearm's history to be permanently logged into the federal tracing system.

Follow the Money

When it comes to the state budget, this legislation is about as cheap as a mandate can possibly get. According to the nonpartisan legislative fiscal note, the bill requires no new state appropriations whatsoever. The eTrace software is built, maintained, and provided completely free of charge to authorized law enforcement agencies by the U.S. Department of Justice. For state-level law enforcement bodies like the Colorado State Patrol or the Colorado Bureau of Investigation, the workload increase is projected to be virtually zero, primarily because they are already deeply integrated into the platform.

At the local level—meaning your city police departments and county sheriffs—there will be a minor, manageable bump in administrative workload. Departments that are not currently using the system will need to spend some staff time officially registering by the September 1, 2026 deadline and training their evidence technicians to input data. However, the exact impact will vary depending on the size of the jurisdiction and the actual volume of firearms they recover in a given year. Because the software is federally funded and there are practical exemptions allowing small agencies to partner with larger ones to share access, taxpayers will not see local budgets strained or tax dollars diverted to cover bureaucratic overhead.

Where This Bill Stands

HB26-1265 is currently Signed Into Law. The latest official action came on 06/01/2026: Governor Signed.

That means the legislative process is complete and the bill is now law. The remaining questions are about implementation timing and how agencies, businesses, or local governments respond.
