A “doing business as” is commonly referred to as a “fictitious name” in this state.
In Pennsylvania you can file your DBA (aka trade name, assumed name or fictitious business name) yourself with your Pennsylvania Department of State. Or, use a legal document service such as LegalZoom to handle the entire process for you.
LegalZoom charges $99.00 (plus state filing fees) for Pennsylvania DBA’s. Click here to learn more about pricing.
