There are numerous reasons to file for a DBA. The most common are:
Increased credibility - A well-chosen name can enhance the credibility of a business, especially for sole proprietors and general partnerships.
The ability to open financial accounts - Many banks require sole proprietorships and general partnerships to take on a DBA before opening an account.
Branding purposes - There are numerous ways that a DBA can assist a company's branding efforts. Some of the most common are to integrate a company's name with their online properties (domain names, social media profiles, etc.), or to position themselves differently to multiple demographics.
Multiple Names – A DBA allows companies to effectively run multiple branding campaigns, or even separate businesses, under one legal entity. As long as the chosen names are not misleading to consumers, and reflect the company's products or services, there is no limit to the number of DBAs that a business can have.
