eCommerceID in description?

Hello Everyone, I am using the eCommerceID in my description to identify the item they are talking about when someone calls me. Right now I am getting the item id and putting it in my html with javascript, but with the oncomming active content ban, i wont be able to use it. I know that sixbit gathers the ID, because we can find it in a search. How do I put it in my listing? Thank you
