Give DHS "A" number if any (DS-230), where to find it?

[letsgetready]

Hello everyone!
I didn't find a clear answer for question #35.
As for me, I already had two type of (nonimmigrant) visas in the previous years (F1 and J1).
But what about the DHS number, how to know if we have one and if we do, where can we find it?
Thanks!

You don't have an A number unless you get EAD or H1B, even then you may not have one.

That was fast!
Thanks a lot, appreciate it!
