Understanding Cisco Devices Serial Number

                         

                   LLLYYWWSSSS

 

This is the standard format of the Cisco Device Serial Number

where

LLL = Location code

YY = Year of Manufacture

WW = Week of Manufacture

SSSS = Base-34 Alpha Numeric Unique identifier= Unique Code

So from Serial Number of an Cisco Device we can figure out its built location and week -year of manufacture .

FOC — Foxconn – Shenzhen, China
JAB — Jabil – Florida
JPE — Jabil – Malaysia
JSH — Jabil – Shanghai , China
