This is taken from uscis.gov. Sounds like e-AR11 submission now changes the address on file for pending cases. Paper AR11 did/does not do that.
However when you are at the last step to fill out and submit e-AR11; there is no place to put the case number. Still it might be a good idea to call the 800 number as well.
Terms and Conditions
This online change of address tool can allow customers to accomplish two different purposes at the same time:
For almost all non-U.S. citizens present in the U.S. for more than 29 days, to comply with the legal requirement to notify DHS of any change of address (currently using Form AR-11, Alien's Change of Address Card)
For individual customers who have pending applications and/or petitions with USCIS to change the address where USCIS should notify them of actions on their case
After filling out the information needed to do an online change of address, you will be asked to select a "Signature" button. By selecting the "Signature" button, you will be certifying under penalty of perjury that the information that you have provided is true and correct.
At the end of this process, you will be given the opportunity to download or print your completed Form AR-11 for your own records. Even though you are not required to print it out, we encourage you to print, sign, and date it in permanent ink and keep a paper copy of the electronic submission for your own records.
If you choose to use this online electronic change of address notification, please do not mail in a Form AR-11. On the other hand if you choose not to use this online tool and instead choose to mail in a paper Form AR-11 please understand that doing so will not update your address on any applications or petitions pending with USCIS.
There are many different internet browsers in use today and they do not all behave the same. Therefore, we strongly suggest you avoid using your "Back" button during this process and instead rely on the links and buttons provided to you within the pages to complete your Change of Address.
USCIS can only accept a change of address for domestic addresses within the United States. If you have moved to a foreign address, please contact the nearest U.S. Consulate/Embassy.
Our system can not store foreign language characters. Please do not place foreign characters in any fields.
