VIN Engraving on Catalytic Converters

NEW CALIFORNIA LAW REQUIRES VIN ENGRAVING ON CATALYTIC CONVERTERS

As of January 2025, a new California law requires all licensed auto dealers to engrave the Vehicle Identification Number (VIN) on catalytic converters for any used vehicles sold at retail. This is part of a statewide effort to combat the ongoing rise in catalytic converter theft. The engraving helps law enforcement trace stolen parts and acts as a strong theft deterrent. Dealers must complete the VIN etching before finalizing the sale.

WHY WAS THE LAW PASSED?

Catalytic converter theft has surged in recent years due to the valuable metals inside. Without a VIN or other identifying mark, it’s nearly impossible for law enforcement to trace a stolen part back to its original vehicle. This new requirement helps deter theft and supports recovery efforts.

 

WHAT ARE DEALERS REQUIRED TO DO?

Under the law, dealers must:

  • Permanently engrave the full or partial VIN onto the catalytic converter before selling the vehicle
  • Ensure the engraving is clearly visible and tamper-resistant

WILL IT COST EXTRA?

Yes, this VIN engraving service is a mandatory step for all applicable vehicle sales, as required by law. A compliance fee will be added to cover materials, labor, and documentation.

BENEFITS OF VIN ENGRAVING ON CATALYTIC CONVERTERS

Engraving your VIN onto the catalytic converter serves as a theft deterrent by making the part traceable, thereby reducing its resale value for thieves. This proactive measure can aid in theft prevention and assist law enforcement in recovering stolen parts. Additionally, it can streamline insurance claims by providing clear proof of ownership for the catalytic converter.

INSURANCE DISCOUNTS

While VIN etching on vehicle windows is more commonly recognized by insurers for anti-theft discounts—typically ranging from 5% to 15% off the comprehensive portion of your policy discounts specifically for etching the catalytic converter are less prevalent. However, some insurers may consider it as part of an overall anti-theft system, potentially qualifying you for a smaller discount. For example, Good2Go Auto Insurance offers up to a 5% discount for vehicles equipped with anti-theft systems and VIN etching.

BUTTOM LINE

Bottom Line Engraving your VIN on the catalytic converter is a cost-effective strategy to deter theft and may offer additional benefits, such as facilitating insurance claims. While direct insurance discounts for this specific measure are not widespread, it contributes to your vehicle’s overall security profile. It’s advisable to consult with your insurance provider to determine if they offer any discounts for VIN etching or other anti-theft measures.
