How Do I Enter My Serial Number and Product Key in AutoCAD?

AutoCAD is a powerful software used by architects, engineers, and designers to create precise and detailed drawings. When you purchase AutoCAD, you receive a serial number and product key that are essential for activating and using the software. In this tutorial, we will guide you through the process of entering your serial number and product key in AutoCAD.

Step 1: Launch AutoCAD

To begin, locate the AutoCAD shortcut on your desktop or in your program menu and double-click to launch the application. Once AutoCAD is up and running, you will see the main interface.

Step 2: Access the “About” Dialog

In order to enter your serial number and product key, we need to access the “About” dialog. To do this, click on the “Help” tab in the top menu bar.

From the drop-down menu, select “About AutoCAD”. This will open a new window with information about your installed version of AutoCAD.

Step 3: Locate Serial Number and Product Key

In the “About AutoCAD” window, you will find your serial number and product key listed under “Product Information”. The serial number is a unique identifier for your licensed copy of AutoCAD, while the product key is a code that validates your license.

Step 4: Enter Serial Number and Product Key

Now that we have located our serial number and product key, it’s time to enter them into AutoCAD. Return to the main interface of AutoCAD by closing the “About” window if it’s still open. In the top menu bar, click on “Help” again, but this time select “Enter Serial Number”.

A dialog box will appear, prompting you to enter your serial number and product key. Type or copy and paste the correct values from the “About AutoCAD” window into the respective fields. Double-check to ensure accuracy, as any typos can prevent successful activation.

Step 5: Activate AutoCAD

Once you have entered your serial number and product key, click on the “Next” button to proceed. AutoCAD will now connect to the Autodesk server to verify your license information. This process may take a few moments.

If everything is entered correctly and your license is valid, you will see a confirmation message stating that AutoCAD has been successfully activated. Congratulations! You can now begin using all the features of AutoCAD.


If you encounter any issues during the activation process, double-check that you have entered the correct serial number and product key. If problems persist, try restarting AutoCAD and repeating the steps outlined in this tutorial. If all else fails, contact Autodesk customer support for further assistance.


Entering your serial number and product key in AutoCAD is a straightforward process that ensures you have a valid license to use this powerful software. By following these steps, you can quickly activate AutoCAD and start creating amazing designs.
