How can you tell if your windshield is OEM?

Quick answer
The clearest sign of an OEM windshield is the vehicle manufacturer’s logo in the glass stamp, alongside the DOT code and AS1 mark. OEM-equivalent glass is made to the same specification without the automaker logo. The VIN identifies the exact part either way, so a matched replacement carries the same features and sensors as the original.
How do I know if my windshield is original?
The fastest way to tell whether a windshield is OEM, original equipment from the vehicle manufacturer, is to read the bug, the etched marking cluster in a corner of the glass. An OEM windshield usually carries the automaker’s logo or name alongside the DOT code and AS1 mark. If the logo is there, the glass was supplied through the vehicle maker; if only the glass manufacturer’s mark appears, the pane is likely OEM-equivalent, built to the same specification under a different brand.
The logo is a clue, not the whole story. What matters for fit, sensors, and calibration is the specification, the camera bracket, the interlayer, the sensor zones, and the coatings, and those are identified by the part number the VIN resolves. OEM and OEM-equivalent glass built to the same specification carry the same features, so a missing logo does not mean the glass is wrong.
A technician confirms the match by reading the bug alongside the VIN rather than by the logo alone. Two panes that look identical can carry different brackets or coatings, and the markings plus the VIN are what separate a matching part from a near-match. See our OEM vs aftermarket guide for how the two compare.
How to identify an OEM windshield
- Read the bug in the lower corner of the glass, usually on the passenger side.
- An automaker logo alongside the DOT code points to OEM glass.
- Only the glass maker’s mark, with no automaker logo, points to OEM-equivalent.
- The VIN identifies the exact specification, logo or no logo.
OEM identification myths
No automaker logo means the glass is wrong for the car.
OEM-equivalent glass is built to the same specification without the logo. The VIN identifies the correct part, and a matched replacement carries the same camera bracket and sensor zones whether or not the logo is present.
You can tell OEM glass just by looking at the tint.
The tint and shade band are set by the glass specification, not by the brand. Two panes with the same specification carry the same tint whether one is OEM and the other is OEM-equivalent.
Only a dealership can install OEM glass.
Any glass shop can order OEM glass when the policy or the customer calls for it. What matters is that the part is matched to the VIN and the camera is calibrated when the vehicle requires it.
More questions about identifying OEM glass
Does an OEM windshield have the car logo?
Usually, yes. OEM glass supplied through the vehicle manufacturer typically carries the automaker’s logo in the bug, alongside the DOT code and AS1 mark. OEM-equivalent glass is made to the same specification without the logo.
How do I identify an OEM windshield?
Read the etched markings in a corner of the glass. An automaker logo points to OEM; only the glass maker’s mark points to OEM-equivalent. The VIN confirms the exact specification either way, so the features and sensors match the original.
Is OEM-equivalent glass the same quality as OEM?
When it is built to the same specification and matched to the VIN, it carries the same camera bracket, interlayer, and sensor zones. The brand differs; the specification that governs fit and calibration does not.
