Who needs to register for an Arizona Trade Name?

When a business wants to operate under a name other than its legal name, many states require it to register its new business name. In Arizona, this is usually optional, but practically, most will want to register.

The requirements and need to register for a Trade Name are found in Arizona state law, A.R.S. § 44-1460.1 These requirements vary depending on the type of business structure. 

Sole proprietorships and general partnerships in Arizona can but are not required to register for a DBA.

Even though it’s optional, a sole proprietorship or general partnership would register a business name with the Secretary of State because it can sometimes be difficult to enter into contracts under the business name. The main issue will be when trying to open a business bank account, as all banks are supposed to see a registered name certificate. 

Even though a business in the state of Arizona can choose to use a name without registering it, registering a Trade Name is an accepted business practice that many will do. This filing prevents other businesses from being able to register it, as every registered business name has to be unique. By registering the name, you are securing it for yourself and making it harder for someone else to use it.

A corporation and Limited Liability Company won’t typically register for an Arizona DBA since a unique entity name is created during the entity formation process. However, some will want to register for a DBA if they have another business or brand name they want to operate in addition to the legal name of the business. This can allow multiple businesses to operate with the liability protection of an Arizona corporation or Limited Liability Company without having to form another entity.

Steps to Register an Arizona Trade Name?

Step 1: Verify Name Availability

Each registered business name must be unique from the others in the state of Arizona. To see if the name you want to use is available, do an Arizona business name search on the Secretary of State website.  

Step 2: Fill out the Trade Name Form

The form can either be submitted online or filled out and mailed in.

Questions on the form include:

  • Desired Trade Name
  • Date the name was first used
  • Type of business entity
  • What the business does
  • Owner’s contact information

Note: The physical form will have to be notarized before signing and processing.

Step 3: Submit the Trade Name Form

After completing the Trade Name form, submit it online or mail it to the Arizona Secretary of State:

Arizona Secretary of State
Attn: Trade Name/Trademark Division
1700 W. Washington Street, FL. 7
Phoenix, AZ 85007-2808

Can someone use my business name after registering an Arizona DBA?

While registering your Trade Name will keep someone else from registering the exact same name in Arizona, it does very little to stop someone else from operating a business under that name in other states.

If stopping others from using your business name is important, you can protect it through a federal trademark through the U.S. Patent & Trademark Office.

Does a DBA need an EIN?

An EIN or Employer Identification Number (also informally called a business tax ID number) is a unique nine-digit number that some businesses will register for through the Internal Revenue Department (IRS). An EIN is required for partnerships, corporations, multi-member LLCs, or any business that has employees.

Sole proprietorships and single-member LLCs without employees can use the owner’s social security number to identify the business.

There is no cost to get an EIN when registering directly from the IRS.

  1. Thanks for this information. I like how you put it together and everything was great except there seems to be conflicting information. At the top it says in Arizona registering a dba name is not required and then under the section “Is a DBA name required in Arizona?” it says it is required. ??

    Also the state has seemed to increase their expedite fee- they are now saying it happens in 24 hours and is $35 (yours says $25).
