If you don't like it, don't do it: the simple rule of thumb.
Otherwise, just fill it out and go down to the SS office and give them the page and a second copy for them to mark received or some stamp form that office. We use a passport for ID, never the DL or state issued ID.
This action moves the SSN Account to Chicago because that is where it moves it. I'm sorry I do not have the specifics, we just KNOW it moves it there because we have never had this fail and have had quite a few people fill out form just as presented.
We just know it is all based on HOW you fill out the form.
Besides, my buddy has filled out all the IRS forms you see on this site multiple times and has been told specifically (via crypto-communications) what will and will not fly and made the adjustments thereto. So, you can do the trial and error for yourself and cultivate a relationship with an agent in the IRS as my buddy has, or you can use the forms provided knowing they have each been through the ringer at least 10 times to get the desired result.
In the end, all of this is form driven bureaucracy crap.
