I'm not sure I fully understand the question but you can register multiple DBA's at your county recorder's office. Go to the office and search their database of current registered names or search online if they provide it. If the exact name you want is not in use you're good to go. I think the application fee is $30 + $5 per extra DBA if applied for on the same form. You then have to put an ad in the paper for 4 weeks stating your intent to do business as your company name. What CA county do you live in?
Business names can't be fictious, they're either registered or they're not registered. Is there a particular name you are trying to register that has been taken by some sort of non-existent business in your county?
