How Do I Get a Flash Drive Serial Number?

A few USB device serial numbers might be found in the device's Properties. Go to Windows Explorer and right-click on the USB drive and select "Properties." In the "Details" tab, several properties are listed in a drop-down list, but "Serial Number" is often not one of them.

The surest way to track down that serial number is to use a utility called USBDeview, a handy tool to find information about USB devices both currently and previously connected to your PC.

Step

Insert your flash drive into your USB port. In your browser, go to NirSoft's website to download USBDeview. Download links for both 32-bit and 64-bit versions are at the bottom of the page. Click on the appropriate version for your system to download and open it.
