Understanding California Vehicle Code 10750: Illegal VIN Alteration

If you’ve been charged under California Vehicle Code 10750, or you’re trying to understand what this law means, you are likely dealing with an allegation involving a vehicle identification number (VIN) or other identifying marks on a vehicle. These cases can be confusing, technical, and often misunderstood—but they are taken seriously under California law. 

This article explains what California Vehicle Code 10750 covers, what conduct is prohibited, possible penalties, and common legal defenses.

What Is California Vehicle Code 10750?

California Vehicle Code 10750 makes it illegal for any person to intentionally deface, destroy, alter, or remove a vehicle’s identifying numbers or marks without proper authorization from the California Department of Motor Vehicles (DMV).

These identifying marks typically include:

  • The Vehicle Identification Number (VIN)
  • Engine numbers or serial numbers
  • Manufacturer-issued identification plates or stamps
  • Other official vehicle identifiers used for registration and tracking

Each vehicle is assigned a unique VIN that acts like a fingerprint. It allows law enforcement, insurance companies, and the DMV to identify a vehicle’s origin, ownership history, and legal status.

Because of this, altering or removing these identifiers without permission is treated as a serious offense.

Purpose of the Law

California Vehicle Code 10750 exists to protect the integrity of vehicle identification systems and to prevent:

  • Vehicle theft and “re-identification” of stolen cars
  • Fraudulent resale of vehicles with hidden or altered histories
  • Illegal dismantling operations such as “chop shops”
  • Misleading or deceptive vehicle sales to buyers

In short, the law helps ensure that every vehicle can be accurately traced and verified throughout its lifetime.

What Conduct Violates CVC 10750?

A person may be charged under this law if they intentionally engage in any of the following actions without DMV authorization:

1. Defacing a VIN or identifying number

This includes scratching, sanding, covering, or damaging the VIN plate or stamped numbers on a vehicle.

2. Altering a VIN

Changing even a single character or digit in a VIN is considered illegal under this statute.

3. Removing or destroying identification marks

Completely removing a VIN plate or engine serial number without permission is prohibited.

4. Adding fake or unauthorized identification numbers

Creating or attaching false vehicle identification markings also falls under this offense.

A key element of this law is intent. The prosecution must show that the action was done knowingly and deliberately, not by accident.

Legal Exceptions

Not every change to a VIN or identifying number is illegal. The law allows for exceptions in certain situations, including:

  • DMV-authorized actions: If the DMV issues written approval for VIN replacement or correction (such as after vehicle reconstruction or salvage inspection), it may be lawful.
  • Manufacturer activity: Vehicle manufacturers may assign or stamp identification numbers during production.
  • Approved restoration or repair work: In rare cases, restoration or repair processes that involve identification markings may be allowed if properly authorized.

Without proper authorization, however, any tampering with VIN numbers may lead to criminal charges.

Is California Vehicle Code 10750 a Felony or Misdemeanor?

In most cases, a violation of California Vehicle Code 10750 is charged as a misdemeanor offense.

Potential penalties may include:

  • Up to one year in county jail
  • Fines up to $1,000
  • Summary probation or informal probation
  • Possible vehicle impound or seizure in related cases

However, it is important to understand that CVC 10750 charges are sometimes filed alongside more serious offenses—such as vehicle theft, fraud, or possession of stolen property—which can result in felony charges and significantly harsher penalties.

Common Situations That Lead to CVC 10750 Charges

People are often surprised by how these cases arise. Common scenarios include:

Purchasing a used vehicle with altered VIN

A buyer may unknowingly purchase a vehicle that already has tampered identification numbers.

Vehicle restoration projects

Classic car restorations or major rebuilds sometimes involve replacement parts, and improper handling of VIN plates can create legal issues.

Allegations of stolen vehicle activity

Law enforcement may suspect that a vehicle was stolen or assembled from multiple vehicles.

Fraudulent resale activity

In more serious cases, individuals may attempt to disguise a vehicle’s identity to sell it illegally for profit.


Possible Legal Defenses

If you are facing charges under California Vehicle Code 10750, several defenses may apply depending on the facts of your case.

Lack of intent

The law requires intentional conduct. If the alteration was accidental or unintentional, this may be a strong defense.

Lack of knowledge

You may not be guilty if you did not know the VIN had been altered (for example, if you unknowingly purchased the vehicle in that condition).

DMV authorization

If you had proper authorization from the DMV, the conduct may be lawful.

Insufficient evidence

The prosecution must prove beyond a reasonable doubt that you knowingly tampered with vehicle identification.

Mistaken identity or false accusation

In some cases, individuals are wrongfully accused due to proximity to a vehicle or misunderstanding of ownership.

Related Offenses

California Vehicle Code 10750 is often charged alongside other vehicle-related crimes, including:

  • Illegal VIN re-marking or misidentification offenses
  • Possession or sale of vehicles with altered identification numbers
  • Vehicle registration fraud or documentation forgery

These related charges may carry more severe penalties, including felony exposure depending on the circumstances.

Why These Cases Are Taken Seriously

Even though CVC 10750 is often charged as a misdemeanor, it is treated seriously by law enforcement and prosecutors because it may indicate:

  • Vehicle theft or trafficking activity
  • Organized fraud or “chop shop” operations
  • Attempts to conceal a vehicle’s true identity
  • Consumer fraud in vehicle sales

Because of this, investigations in these cases are often detailed and aggressive.

What You Should Do If You Are Charged

If you are accused of violating California Vehicle Code 10750, it is important to act quickly:

  • Do not ignore the charge or court date
  • Do not attempt to alter or “fix” the vehicle identification yourself
  • Preserve all documents related to the vehicle purchase or ownership
  • Seek legal guidance as soon as possible

Early legal representation can help protect your rights and may significantly impact the outcome of your case.

Final Thoughts

California Vehicle Code 10750 is designed to prevent fraud and protect the integrity of vehicle identification systems. However, not every allegation involves intentional wrongdoing. Many people facing these charges are unaware of any issue until they are contacted by law enforcement. Because these cases often depend on technical evidence and intent, having a strong legal defense is essential.
