@Shiva512  I think there's a bit of a mix-up in terminology here.

The license code (number) (and product number) are indeed listed in CAMPS under your product history.

The validation code can be a little different, and depending on how outdated your QB product is, Intuit may well refuse to provide it. I don't know exactly how far back the CAMPS cut-off is.

There is also the Payroll Service Key, but that's a different beastie altogether.
