I bought two sorcerer AP's, one for myself and one for my wife. (we are direct purchasers and are both on the deed.) I bought mine online, but I had to call MS for my wife's since I was upgrading a date based ticket she did not use on a previous trip where we had moved the ticket dates forward so it would still show in
MDE.
In MDE her AP appears with a blue background and says "Disney Vacation Club Member Disney Sorcerer Pass (Ages 10+)."
In MDE my AP has the same language quoted above but appears with an orange background and includes additional wording in red type below the barcode that says, "NOT VALID FOR ADMISSION Must show ID at ticket window before using."
It seems MS verified her eligibility when they assigned her AP to her MDE profile, but the system did not auto-verify my eligibility when I bought online, even though I assigned it to my MDE account which shows
DVC Y.
I therefore assume if you purchase by calling MS you are good to go, but if you purchase online you need to show ID before the first use.
