For about a year, I had been getting pin codes from Disney, up until now I had no plans to go. The last pin code prompted me to call and book. The name on the pin code did not match me. While researching on Disney's side they mentioned last name of Dixon living in Illinois. I emailed the Disney department that handles sending pin codes and I gave them the name and state I had been told. I just got and email saying they had corrected their side so they will be getting the codes from now on. Always call and see if you have a pin code because maybe you are getting them but through someone else's email address.
