Can you have a separate EIN # for different DBA’s under the same LLC?
No. You don’t want to (and are not allowed) to do that.
A DBA is not a separate entity. It’s just a way of letting the state and the public know that the LLC also does business by other names.
Only a separate entity can have a separate EIN.
There are some unscrupulous promoters out there telling people that they can eliminate a bad credit history, for example, by getting EINs under various business names.
This type of scheme won’t work for a variety of reasons, and I don’t want to get started on a rant, because this is very fraudulent and people unknowingly get caught up in it.
