Possessing Firearms with Defaced Serial Numbers NYC Penalties.

Thanks for visiting Federal Lawyers, a second-generation criminal defense firm managed by our lead attorney, with over 50 years of combined experience defending firearms cases throughout New York. Police find a gun with a filed-off, scratched-out, or otherwise altered serial number? Your facing serious felony charges - both state and potentially federal. New York Penal Law § 265.02 makes it criminal possession of a weapon in the third degree to possess any firearm with a removed, defaced, or altered serial number. That's a class D felony carrying 2-7 years. Federal law adds another layer - 18 U.S.C. § 922(k) makes it illegal to possess, receive, or transfer any firearm with an obliterated serial number. Up to 5 years federal time. Prosecutors charge these cases aggressively because defaced serial numbers indicate the gun's been used in crimes and trafficked through illegal channels.

Why Serial Numbers Matter

Every commercially manufactured firearm has a serial number stamped on the frame or receiver. These numbers serve critical law enforcement functions.

Tracing Crime Guns

When police recover a firearm at a crime scene, they submit it to ATF's National Tracing Center. ATF uses the serial number to trace the gun from manufacturer to first retail sale - identifying which dealer sold it and who purchased it. A gun with a defaced serial cant be traced. That's why people deface them - to prevent tracing back to the original purchaser or linking to previous crimes.

Linking Guns to Multiple Crimes

Serial numbers connect one firearm to multiple criminal incidents. Gun recovered at a Manhattan shooting has the same serial as a gun used in a Brooklyn robbery? That links the cases. Defacing the serial breaks that chain.

New York Law: PL § 265.02

PL § 265.02(4) makes it a crime to possess "any firearm... which has been defaced for the purpose of concealment or prevention of the detection of a crime."

Class D felony - 2 to 7 years. The statute doesn't require you to be the person who defaced the serial. Possessing a gun someone else defaced is enough.

What "Defaced" Means

Defaced means removed, obliterated, altered, or covered in a way that makes the serial illegible or difficult to read. Filing it off, grinding it down, scratching it out, stamping over it, covering it with metal or polymer - all qualify.

Partial defacement counts. If enough of the serial is removed or altered that it cant be fully read, that's defacement. You dont need to obliterate every digit.

The "Purpose" Element

The statute requires the defacement be "for the purpose of concealment." Prosecutors must prove someone defaced the number for that purpose - but they dont need to prove YOU did it. If you possess a gun with a defaced serial, prosecutors presume it was defaced for illegal purposes.

I've defended cases where clients argued they didnt know why the serial was defaced. That doesn't help - possessing it is the crime, regardless of who defaced it or why.
