I and my hu*****and are filing the AR-11 for changing address through USCIS website. We don't know which A number we should use, the one from the I-94 or the one from the receipt of I-485 (pending)? Both of them have 9 digits.

Another question: I have filed the AR-11 by mail 3 month ago and did not notify the USICS for the pending 485. Now can I change the address of the pending 485 through the website also?

Thanks a lot for the help!!!

A number is an alien number in I-485, every one has one,
