I received I-485 AOS interview and noticed the different A# numbers, iam confused

[devss]

Hi,

I am confused about the A# number.Here are the details.

I married USC came on K-3 visa in MARCH 2003 .Applied I-130,in April, 2002 didnt heard till now.

I applied for I-485 AOS, and i received NOA :RD 23rd AUG 2003
ND 8th OCT 2003
FP 21st NOV 2003
On this first NOA there was no A# but they gave the applicant number
like A 038715623(this is a sample number not my real one) under that my name is printed.The same number has been printed on the EAD like A#038715623, so iam thinking that my A# the one which is printed on EAD.

Last week i received another NOA which says I-797C, NOA on this the details are like: they gave my initial date of interview,DEC 2004 my application number( same on all documents), other interview details and also
A#NUMBER HRER IAM CONCERNED COZ which differs with the EAD A# number,Further i also noticed that on my I-94 the number is same with that of EAD.

Can any one clarify why this discrepancy with A# number?If its a mistake of the INS whom i need to call?

Or do i need to consider the A# which is on I-797C NOA.

I'd appreciate any of your valuable inputs.
