Well, it depends, there are people who got it after a week, after 2 week, 3 weeks, one said he got it the next day. Me however, got it on the 5th week.

You can go to the office after a week to see if you been ASSIGN a number (People also recommended that you can call the office, however everytime I called they refuse to tell me anything unless I gave them a SS number to check o.O). I would rather you get the actual card, because I went to take the exam today, there was a guy who didn't have his card (or any ids in fact), they make a deal out of it (doesn't seem to like it).
