Your Alexa device’s serial number number is a unique identifier that can be used to determine its firmware version. Here’s how to find it.
- Open the Alexa app on your mobile device.
- Tap the Devices tab, then tap the device whose serial number/generation number you want to find.
- Tap the Device Info tab.
- Scroll down to find the Serial Number/Generation Number.
Alternatively, the serial number can also be found on the device itself. It is usually printed on a label on the underside of the device.
