Different A# on I-485 receipt and EAD card

[nikbuds]

Hello,

unfortunately or fortunately i just noticed that i have a different A# on the EAD card and different A# on 485 receipt.

I have renewed my EAD card in past and got the new one with no problems. (using the A# on the EAD card)

I am applying for the Advance Parole (previous expired) and it needs my A#. I dont know which one to give.

and why is it different. most people i talked to have the same A# on both.

any clues?

Also, do i need to attach a copy of my EAD card to my AP application or just passport and drivers license should suffice.

ps: my husband is the primary applicant and I am the spouse...he has the same A# on 485 receipt and on the EAD card.

thanks
