How do you verify DBA account?

[seanpbh]

If I set up a stealth account using a "Doing Business As" name, how do I verify this later on? What will they ask for?

Is DBA or LLC better to use?

I have ran out of people whose id I can use to set up stealth accounts, what other options could I try?
I have set up 3 accounts and am looking to get 8 in total. I am located in Canada
