What is the SPC Code?

I'm on a train, going across Canada. Yesterday my Verizon tech set up my account for more Data for Canada ( I live in the US ). she emailed me instructions:

Settings→General→Reset→Subscriber Services→Reset Account. When I go from SubscriberServives, it wants either an Reprovication, or Reset Authentification (WHICH WANTS AN SPC CODE ) I do not know WHAT SPC Code is. Every 'code' I put in is Wrong!! I have 4more hours with ViaRail WIFI!!!

Please Help :-)
