I wish I knew, I've bought like 3 cans of paint that people have posted the numbers of, and they all don't match (yes I've sanded and prepped it after each time the paint didn't match)... well not close enough for me. I'm just going to go to my auto body shop and have them match it.
When i got my A pillar painted at the local body shop, they told me there was no paint code for the pillar. What they did was called an "eye match". It turned out really good and looks like stock. It matches the other A pillar!!
