B2 extension,I-539, What's A#?

Hi, All,

I'm extending B-2 visa for my mom. Her visa will expire on Dec.5 but I want her to stay two weeks more so we can go back China together. When I fill in the I-539 online, there is a place requiring A#. Do I need to fill in it? What is the A# for B-2 visa? Is it the 8 digit red code in the visa?

Thanks a lot for answering my question.
