WD WWN & DCX codes what are those mean?

[Scorpion]

Hello,

Recently I noticed 2 new codes on the WD label drive.
WWN & DCX.
Those are near the the DATE & DCM.

Are those codes (WWN & DCX) important in some way to find a good donor match?
Should I look the first or last few letters of each code?
In general, what are those codes mean?

Best Regards,

Thank you for the info. I run through that wiki but it doesn't help :/
More over there is no any mention on what is DCX.
The WIKI says that it has some rules for indentifications but it doesn't say what rules or how it is belong to WD uses or their hard drives.

Code:

50014EE123456789
$######*********

$ = NAA (Network Address Authority)
# = Western Digital's OUI (Organisationally Unique Identifier)
* = vendor defined number

My investigations lead me to believe that the DCX is related to the model number suffix in 3 of the characters, namely the "Family Identifier".

Model Number Format for OEM and Distribution Channels:

I haven't seen WD's internal document, but here is an explanation in Russian:

Here is Google's English translation:

For example, if the DCX is "9003ZC030", then the corresponding model number suffix should look like "x0Z3xx". One possibility is "00Z3A0".
