Answering your specific questions

Missing A-Number: It is normal to file without an A-Number. The official instructions for USCIS forms state that you only provide an A-Number "if any." If you do not have one, you simply type or print "N/A".

Confirmation and your account: You access the E-COA tool directly inside your USCIS online account under the "My Account" dropdown menu. Because the tool lives inside your account, your address update is linked directly to your profile.

Filing twice: You do not need to file both online and by mail. Changing your address online eliminates the need to file a paper Form AR-11 by mail.
