You don't need any number, nor anything else concerning the Swiss Travel Pass. All you have to do now is arrange for your Glacier Express seat reservations (mind not to buy the train journey itself, as the ride is for free with your Swiss Travel Pass). As long as you have both your reservations and your Swiss Travel Pass at the moment of traveling, all is fine.
