Thanks for being patient. I don't have an answer for you, and unfortunately our registration manager stepped down so no one is available to field these questions. I think that in all likelihood though, if you didn't get your registration number when you registered, that you will probably have to just wait until you get your badge. Otherwise, answering your question countless times for X registrants might become burdensome on the registration folks.
That is just my guess. But I am not involved with registration so my answer is in no way authoritative.
