For reasons only Roku can fathom, Roku devices have two unique numbers and at times they're both referred to as "serial numbers". Check under Settings->System->About and you should see both numbers listed as "Serial number" and "Device ID". One of those should match what shows up under your linked devices.
Hi MSM13,
Thanks for reaching out to the Roku Community.
We will go through these details with you. Can you let us know if you obtained your Roku device serial number from the device itself or from the Roku device setting menu? We recommend going to Settings > System > About, as you can find the device's serial number and associated Roku account email address on this page.
After verifying the email address associated with your Roku device, please try logging into your Roku account again. Once logged in, scroll down to the "My linked devices" section and locate your device to verify that it is listed there.
Keep us posted on what you find out.
Regards,
Nimfa
Do you need to get to "settings > system > about" from the TV? I don't see those options on the web.
EJ4, yes. Press Home on your Roku remote a few times and you'll see the menu on the left of the screen. Select "Settings", press OK, select "System", press OK, select "About", press OK.
To see the devices linked to your Roku account online, go to https://my.roku.com and scroll down to "My streaming devices & TVs".
