I recall when I was going through the paperwork when I bought it that it said 2 years. They even give you a place to put the date you start using the card so you know when the 2 years are up so youcan discard it. I found this review while doing a quick google search but if you read it carefully half way down he refers to the 2 years that X-rite rates it's life expectancy

"Also, the panels will fade in time and X-Rite say that the life-span of a ColorChecker is about two years."

Here is the link

Hope that helps...
