Hey Kane,

The first two digits are manufacturing date codes, the next four characters are the lot trace code, last character is an assembly site code

Hi, Dylan

Thanks for you reply.

The first 2 digits in picture is 43, what manufacturing date does 43 stand for?

Would you like to tell me how to calculate the date by these 2 digits?

Thanks, Kane

Hi Kane,

The 4 should indicate the year and the 3 should indicate the month. So for this it would be April 2014.
