Just received a PIN via my email, but it is my son's street address. It will save me another $200 over the current RO discount in January. Will they let me use it?
As long as it is in your name, the answer should be yes. My mom has gotten several snail mail PINs at my address, since I'm the usual travel planner in the family, and has used a couple without issue. With an e-mail PIN I think the mailing address would be even less relevant - after all, people move all the time without changing e-mail addresses!
