DBA stands for “doing business as.” A DBA gives you the legal backing to operate your business under a different name other than your own name (in the case of a sole proprietorship) or the registered name of your business. A DBA is only used for branding purposes. A DBA isn’t a type of business structure and won’t protect your personal assets.

Please note that you can apply for a DBA when you first register your new business, or you can apply for a DBA later on if you decide to make changes to your business. It is important to state that a business can use a DBA to advertise, transact business, and open bank accounts.

If you plan to run your business in Arizona under any name other than your own name or the registered name of your business, you are expected to file a DBA name registration.

Also, since a company’s official legal name must include a business type designation—like LLC, Inc., or Co.—businesses that do not want to use that designation in marketing must register a DBA. Having said that, filing an Arizona trade name, also known as an Arizona DBA (doing business as), is an easy process that is achieved by filing online with the Secretary of State.

This article will help you understand how to file a DBA in Arizona. We will show you a step-by-step process on how to file a DBA in Arizona and what you need to do after filing your DBA. Without any further ado, let’s begin:

Steps and Requirements to Set Up a DBA in Arizona

STEP ONE. Start with an Arizona Trade Name Search

If you intend to fill a DBA in Arizona, the first point of call is to search for a trade name. Please note that in Arizona, your Arizona trade name must be unique and must also meet Arizona’s business name requirements. To get this process started, you have to visit the Arizona Secretary of State’s website and search for your new DBA name to make sure it isn’t already in use.

The next step to take in this regard is to review Arizona’s naming requirements. In Arizona, your trade name should not include the following words and phrases without approval from the Arizona Department of Financial Institutions:

Bank; banker; banking; banc; banco; banque; credit union; deposit; savings association; building association; savings and loan association; building and loan association; savings bank; thrift; trust; and trust company.

How can you tell if the name is available?

To make sure you are not using another company’s name, it is best you conduct a name search on Arizona eCorp site.

Check if the URL is Available

If you want to give your potential clients a sense of professionalism, it is best you check to see if you can use your DBA name as a web domain. The customers you need are on the internet, so if you want to expand your brand and build your customer base, a business website is a necessity.

With so many people offering the service, building one won’t cost you a pretty penny and would pay off in the long run.

Set up a Professional e-mail Account

First impression is critical especially in business where your main aim is to win clients and customers. In this modern era, many people are becoming very selective and conscious when it comes to communication via e-mail. Spam messages from unwanted sources tend to make people scared of opening new messages, and this is where a professional e-mail comes into play. Some of the best professional e-mail services you should consider are:

  • G suite
  • Zoho Workplace
  • Rackspace
  • Office 365Step
