I am sure you applied in CSC. Is it right?. Yes i got WAC number from my lawyer. I have not seen physical reciepts thought. Based on those reciept numbers i created profile. So far the AP and EAD status email are coming and i am getting approval notices. I did not get actual EAD though. I dont really understand why you are not able to check atleast the case number for your wife's EAD, Even though you got actual approval and card. Did you call USCIS. Just call them to verify your address. Might be it helps you. But for sure they will ask for WAC number. I dont know what to say. might be they track based on your available WAC numbers. When did you apply and what is your PD on labor. is it your own or substiutue?.For sure if they dont accept your application, they probably wont give EAD for your wife?. Just think logically. Dont worry man. I think your 99% ok.
