Who Needs One in California?
Anyone that names a business that does not include their name or the names of the business owners needs to file for an FBN in California. Sole proprietors, partnerships, limited partnerships, LLCs, or corporations can all require an FBN to be filed with the clerk of the county where they want to do business.
Why Is an FBN Required in California?
If you want to get a business license, open business bank accounts, apply for a business loan, and so on, and you are not doing business using your name or the name of the business owners, then you need an FBN. Without one, you cannot enter into legal agreements with other businesses, such as vendors or suppliers. Nor are you allied to legally sign contracts, apply for small business loans, etc.
