How to Find Your Garage Door Model Number

Most garage doors don’t wear their identity on their sleeve. If your garage door needs a repair or replacement part, one of the first questions any technician will ask is: “What’s the model number?” If you don’t have that information ready, you could end up ordering the wrong part, wasting time, and delaying service. Knowing exactly how to find your garage door type model number will save you frustration and help speed up the repair or replacement process.

Why the Model Number Matters

The model number of your garage door tells you the make, style, material, insulation type, and sometimes even the color. This number helps technicians match parts correctly and make recommendations that fit your exact door. Not every hinge, panel, or spring works with every model. If you guess, you’re likely to get it wrong.

Start with the Garage Door Manual

If your garage door was installed by a professional, the installer might have left behind a user manual or installation packet. This packet often contains a sticker or printout with your door’s model number and specifications. If you can’t find the manual, don’t worry. There are still several ways to identify your garage door model number directly from the door itself.

Check the Inside of the Door

Look for the Manufacturer’s Label

Most garage doors have a sticker placed on the inside of the top panel. Stand inside your garage with the door closed and check the top left, top right, or center of the panel closest to the ceiling. Use a flashlight if needed.

The label might include:

• Model number
• Serial number
• Manufacturer name
• Door size and type
• Wind rating (in some cases)

This label is usually placed where it’s protected from weather and visible during regular inspections. Once you find it, write down the entire string of numbers and letters. Some model numbers look similar, and small differences matter.

Don’t Overlook the Track

Some manufacturers, like Clopay, place model and serial numbers on the vertical track near the bottom. Look for a label or sticker facing toward the inside of the garage, near the roller bracket or safety tag. If you spot it, take a photo. These labels can fade over time, especially in garages with a lot of sunlight or moisture.

No Label? Use These Clues to Identify the Model

If the label has worn off or was never installed, you can still get a good idea of your garage door type and model number by gathering a few key details.

Check the Sections and Panel Design

Count the number of panels or sections in the door and note the pattern. Is it short panel, long panel, or flush? Does it have windows? If so, where are they located? Some models are only available in certain panel layouts or window designs.

Measure the Door

Write down the exact width and height of the door. This helps narrow down the product line and will be important when checking manufacturer catalogs or contacting a service company.

Material and Insulation

Is your door steel, aluminum, or wood? Knock on it to check thickness. Some steel doors are hollow, while others are insulated with polystyrene or polyurethane foam. Look at the side of the door for clues. Insulated doors often have a sandwich-style panel with a sealed edge. Knowing these details won’t give you the exact model, but they will help a technician narrow it down and cross-check manufacturer specs.

Contact the Manufacturer If Needed

If your garage door has a brand name visible (like Haas, Clopay, Wayne Dalton, or CHI), visit their website and check for product identification tools. Many manufacturers offer support pages where you can enter part of a serial number or browse by door style.

Still not sure? Take a clear photo of the door from the outside and inside, then email it to customer support. Be sure to include measurements and any other details you’ve gathered. Most support teams can help you track down the correct model.

Model Number vs. Serial Number

Model numbers and serial numbers are not the same thing. A model number tells you the product line and style. A serial number is unique to your door and may include manufacturing date and batch information. Both can be helpful, but the model number is what you need when ordering parts or requesting service. If the only thing you can find is the serial number, try searching that number online with the manufacturer’s name. Some serial numbers decode directly to the model number.
