Interpreting serial numbers

Is there any knowledge here about interpreting serial numbers? I bought my OT pretty early and it is stamped feb 2011 - this information forms part of the serial number but i’m curious about the rest of it, like do the other numbers denote which number OT it is or is it more random?

What part of it is the date?

mine says - 11 02 - on the serial sticker then the first part of the serial number corresponds to this…which is pretty common practice i believe
