Cisco serial number decoder

Tuesday, 8th October 2013

This is a javascript implementation using some info on the serial number encoding pinched from a blog post of John Higham

The format is just LOCYYWWSSSS, where LOC is the location code, YY is the year minus 1996, WW is the week and SSSS is the serial id. If you can't be bothered remembering all that then use this javascript decoder thingy.

I haven't been able to figure out if the three letter locations map directly to something like UN location codes or if there is some magical list of such things somewhere, so I just print them out as is.

If this was of use to you then my type 7 password decoder might be of use to you as well.
