How can I check the address attached to my Apple ID prior to my AppleCare registration ?
First, verify which Apple ID you used to register your AppleCare. If you believe that you used the same ID you are now using for Discussions, click the "Support" section of the menu bar at the top of this page. Scroll down the main Support page to the "AppleCare" section in the far right column, and click on the link for "Register and View AppleCare Agreements>"
You will then either log in to your account, or you will see a list of the "AppleCare Agreements" that have been registered to your Apple ID and that are current. On the left you will see the "Agreement Type" column, and on the right the "Agreement Number" column. Find "APP - IMAC/EMAC" on the left and the enrollment number of the AppleCare Plan that you registered for your iMac on the right. If the enrollment is listed as you expect, you have verified which account needs to have its Account profile updated. If you have no AppleCare Agreements registered to that Apple ID, there will two empty boxes below the two column headings, and no listings.
If your Agreement isn't listed, that means you used a different Apple ID to register the AppleCare for your iMac. Log out and then log into the correct Apple ID and repeat the above until you find the Apple ID to which you registered your iMac's AppleCare. Once you have logged into your correct account, go to
http://myinfo.apple.com/
and check the address listed in your account profile. That will be where your AppleCare Certificate was mailed. Update your profile if necessary, although it will probably be too late to impact the mailing that already went out. Log out.

Not only is it a good idea, for proof of purchase, to retain the iMac's purchase invoice, either the original store Invoice or a copy of the emailed Invoice you received from Apple, but it may be necessary to also provide proof of purchasing AppleCare. DON'T rely on Apple to provide either of these in the future. In the past they have not been able to do so, but may still require that you be able to do so. If you can not, you may have to accept their "estimated" date of purchase, which I've found can be wrong by at least FOUR months.
