Most businesses in Alameda County will be required to file a Fictitious Business Name Statement. Check with the agency that issues business licenses in your municipality to verify the need for a Fictitious Business Name Statement.
A fictitious business name, in the case of a sole proprietorship or partnership, is a name that does not include the full name(s) of the individual(s), or a name that suggests the existence of additional owners (e.g. Associates, and Sons, etc.). In the case of a corporation, a fictitious business name is any name other than the full corporate name as shown in the articles of incorporation.
After the fictitious business name statement has been filed with the county clerk, the statement must be published in an Alameda County newspaper of general circulation in the area where the business is to be conducted. The statement must be published once a week for four consecutive weeks with five days between each date of publication. Note that you will also need to file an affidavit of publication with the county clerk within 30 days after the completion of the publication cycle.
