USA B1/B2 VISA/BCC Number?

Where do you find the ID# on the B1/B2 card? Any help would be great.

From the document????

From the card. When I look at the front of the card there are 3 lines at the bottom. The first two have letters and numbers and the last is the name. We do not have many so I am not very familiar with these cards. So, I do not know how to pull the ID# from the string of characters. Are there any indicators?

New or old style?

The card was issued in 2006 and looked identical to the card in our 2008 ID verification booklet. There are no red letters on the card.
