BBBVC SerialNumber label signification (Seeed beagle bone black)

Hello, Here is a link https://www.mattwind.com/2015/03/beaglebone-black-serial-number-from.html that detail how to get Serial number from EEPROM. We found this information in many site, and use it for our production process.

–> At least can you confirm the 4 characters SBB0 will be always the same with your current version of BBBK?
–> If you have any additional information about the “36” number signification, it would be great for us?

Thank you, Thierry
