A Serial Number will not help identify the drive … the Serial Number is your Warranty which you use to Register the drive with WD. (so it’s not a good idea to post it on public forum for privacy reasons.)
There should be a Model Number or Part Number on the back of the drive.
If there isn’t, then download WD Diagnostics and it will disaply the Model Number in the software.
P.S. it’s most likely a WDBMWV0020BBL-NESN
