Windscreen Codes Explained: What They Mean and Why They Matter

When it’s time to replace your windshield, one of the most overlooked but important details is your windscreen code. At GlassFixit, we often encounter customers who are surprised to learn that their car’s windshield isn’t just a piece of glass—it’s a carefully engineered component with built-in codes that tell you exactly what specifications it follows.

Let us break down everything you need to know about windscreen codes, including where to find them, what they mean, and how they help ensure the perfect replacement.

What Are Windscreen Codes?

Windscreen codes are a combination of numbers, letters, and symbols etched or printed on the bottom corner of your windshield. These codes provide crucial information about the type of glass, manufacturer, country of origin, safety standards, and additional features like tint, heating elements, acoustic layers, and UV protection.

Why Windscreen Codes Matter

These codes are more than just markings—they are your guide to the correct replacement glass. Here’s why windscreen codes are essential:

• Safety Compliance: They confirm the glass meets DOT (Department of Transportation) or ECE (Economic Commission for Europe) safety standards.
  
• Feature Matching: If your original windshield had built-in sensors, rain detection, or tinting, the code ensures your new one will too.
  
• Precision Fit: GlassFixit uses these codes to source OEM or equivalent windshields that perfectly match your vehicle’s make and model.
  
• Insurance Claims: Many insurance providers require code verification to approve coverage or reimbursement.
  

How to Read Windscreen Codes

Here’s a quick breakdown of what the typical elements in a windscreen code represent:

• DOT Number: A U.S. safety compliance indicator.
  
• E Mark (e.g., E1, E2): Indicates compliance with European safety standards and the country of approval.
  
• AS1, AS2, AS3: Glass type classifications, with AS1 being the highest quality (used for windshields).
  
• Manufacturer’s Code: Identifies the company that produced the glass.
  
• Date Code: Tells you when the windshield was manufactured.
  
• Optional Features: May include symbols for solar control, rain sensors, acoustic layers, or heads-up displays.
  

Where to Find the Windscreen Code?

The code is usually etched into the lower corner of the windshield, near the dashboard—most commonly on the driver’s side. You might need to step outside the vehicle to view it clearly.

What If the Code Is Faded or Missing?

If the windscreen code is unreadable, don’t worry—GlassFixit can help. We’ll reference your vehicle’s VIN number and manufacturer specifications to ensure we install the right windshield with all the original features intact.
