At the present time, the only carbs that can be "hidden" are sugar alcohols and other syrup sweeteners. Look for the following ingredients:

• glycerine/glycerol
  polydextrose
  glucose polymer
  isomalt
  maltitol
  sorbitol
  erythritol
  inulin
  HSH (hydrolysed starch hydrolysate)
  maltitol syrup
  mannitol
  xylitol

If your product doesn't have any of these ingredients in them, then the carb count on the label is probably accurate. Many of the low carb protein shake powders are as low carb as they say on the label too ... as long as none of those ingredients are listed. (beware ... I've seen some soy shake powders labelled sugar-free, but they contain fructose!)

For more information about those ingredients, click on Low Carb Tips from the orange menu bar at the top of the page, and read the article Sugar Alcohols. It will explain a little more why and how manufacturers can get away with hiding them, and not declaring the true carbs on the label.
