How to get a device serial number

Sometimes, Amazon may ask for the device serial number (DSN) of your Alexa-enabled device such as Echo or Echo Show, in order to perform debugging or whitelisting.

Note that for customers of other regions such as UK or Germany, replace amazon.com with amazon.co.uk or amazon.de as needed. Other steps remain the same.

To get the DSN of the Alexa-enabled device:

1. Login to http://alexa.amazon.com
2. Go to Settings and under Devices, select the desired device
3. Scroll down to the bottom and find the "Serial number" under About, that is the DSN
