This code has been stored in your profile. You can remove it, if you want by editing the "Contact Information" in "My Profile" on SPG.com.
I've found three different corporate codes added to my profile this year after booking rooms by phone. While they may have been good for a particular booking, I didn't want them on my profile. I've saved them, though, and try them sometimes when I'm searching for better rates.
