What is the numer at the fourth row on the front side of Intel i7 CPU? (pictured)

enter image description here

I saw two Intel CPUs in the store described as "Core i7-6700" but have slightly different prices (both OEMs). Only the difference I found is the numbers on the front side.

P.S. I'm already guessing it is kind of a serial number but not sure.

That is the Finished Process Order serial number, and is essentially a lot number. It is used by Intel to determine warranty information.
