    4 Steps to Register Your Business Name in Arizona

    When registering your business in Arizona, take the necessary step of officially registering your business name in the Copper State. To assist you with this process, we have provided a concise guide detailing four straightforward steps to ensure your business name receives official recognition in Arizona.

    Step 1: Choose Your Business Structure in Arizona

    Choosing the right business structure is a crucial decision that will significantly impact your venture. It’ll affect essential aspects such as liability, taxation, and management. In Arizona, you have several options to consider for your business entity.

    Sole Proprietorship

    In Arizona, a sole proprietorship is the most straightforward type of business. It consists of a single owner legally regarded as the business itself. Although it’s easy to establish, it’s important to note that the owner assumes personal responsibility for all debts and obligations of the business. While registration with the state isn’t required for sole proprietorships, there may be a need for local permits or licenses.

    General Partnership

    If you’re embarking on a venture with one or more colleagues, a general partnership may be the right choice. This arrangement entails all partners sharing both the gains and setbacks of the business. 

    Like a sole proprietorship, establishing a general partnership doesn’t necessitate registration at the state level. However, it might require filing a “Certificate of Registration” (DBA) with the county where your business is located.

    Limited Partnership (LP)

    In Arizona, a limited partnership is formed by general partners who are personally liable without limits and limited partners who have limited liability but don’t participate in the business management. Establishing an LP in Arizona involves filing the “Certificate of Limited Partnership” with the Arizona Corporation Commission.

    Limited Liability Company (LLC)

    Many businesses opt for an LLC because it offers flexibility and liability protection. It combines the benefits of a corporation, such as limited liability, with the simplicity of a partnership. In Arizona, to establish an LLC, you must submit “Articles of Organization” to the Arizona Corporation Commission and create an Operating Agreement that details the company’s management and ownership structure.


    A corporation that offers limited liability protection is a distinct legal entity separate from its shareholders or owners. Arizona presents two options for corporations: C-corporations and S-corporations.

    To establish a corporation in Arizona, submit the necessary “Articles of Incorporation” to the Arizona Corporation Commission, depending on your chosen type of corporation. Corporations have stricter requirements that include drafting bylaws, issuing stocks, and conducting regular meetings with the board of directors and shareholders.

    Selecting the appropriate business structure in Arizona is essential as it will affect both the legal and financial aspects of your business. It’s highly recommended that you seek advice from a legal or business professional to make an informed decision based on your specific circumstances and needs.

    By carefully following these crucial steps and making well-informed choices regarding your business structure, you’ll successfully register your company’s name in Arizona while establishing a solid foundation for growth and prosperity.

    Step 2: Select a Unique Business Name in Arizona 

    Choosing an original and fitting name is a vital aspect of creating your brand’s image. Next, we will explore three methods for naming your company in Arizona and the essential measures to safeguard your selected name.

    Legal Entity Name

    When you register your business in Arizona, select a unique legal entity name. This chosen name serves as the state’s way of identifying your company and helps avoid potential conflicts with other businesses. 

    Arizona has specific naming laws that require the selected name to represent the nature of your business operations accurately. To confirm the availability of your desired name, you can consult the eCorp database maintained by the Arizona Corporation Commission.

    To safeguard your legal entity name, register it according to the specific business structure chosen during Step 1. Whether you opt for an LLC, Corporation, or any other entity formation, securing a distinct and exclusive name is vital in establishing a strong brand presence for your business.


    Ensure the security of your business name or logo nationally by acquiring a trademark. A trademark is an invaluable form of intellectual property protection prohibiting others from utilizing a similar name or logo for comparable goods or services. 

    Before proceeding with your chosen name, conduct an extensive search within the USPTO database to confirm that no one else has registered a similar mark.

    While having a trademark provides nationwide protection, note that it doesn’t automatically grant you unrestricted usage rights for the name or logo in all situations. If you have plans to expand your business beyond the boundaries of Arizona, obtaining a trademark becomes an influential tool in safeguarding your brand identity.

    Doing Business As (DBA) Name

    In Arizona, you can register your business using one name and operate with a different name. This alternative name is referred to as a Doing Business As (DBA) name or a trade name. Unlike the official entity name, a DBA doesn’t need to be unique at the state level. 

    To officially establish a DBA, submit a “Trade Name Registration” form to the Arizona Secretary of State’s office.

    While DBAs are subject to federal trademark laws, they provide flexibility if you intend to run multiple businesses under different names or if you want to rebrand without changing your legal entity’s name.

    Protecting Your Brand Identity:

    By exploring these various choices for naming and adhering to the necessary protocols for registration, you can confidently establish your business identity in Arizona while also protecting your brand. 

    It’s crucial to remember that selecting a unique and appropriate name within Arizona is vital in establishing a strong presence and gaining recognition among customers and competitors.

    Before making a final decision on your business name, conduct thorough research to ensure its availability both at the state level (for legal entity purposes) and nationally (to secure trademarks). This proactive approach will pave the way for a successful and distinctive business endeavor within Arizona’s thriving entrepreneurial landscape.

    Step 3: Check Business Name Availability in Arizona

    To register your company in Arizona and choose a business name, verify that another business isn’t already using the desired name. To conduct a comprehensive search for the availability of a business name, you should follow these three vital steps.

    Trademark Search

    Start by thoroughly searching for federal trademarks to determine if your desired business name has already been registered. Federal trademarks hold more weight than state-level registrations, so it’s important to check on this level. To conduct a federal trademark search, visit the US Patent and Trademark Office (USPTO) website and utilize their TESS Search tool.

    Ensuring that your chosen name isn’t already trademarked is crucial to avoid legal disputes and the need for rebranding in the future. If you discover that your preferred name has already been trademarked, you must devise an alternative business name.

    Arizona Business Name Search

    Once you have confirmed that your business name isn’t already trademarked, the next step is to check its availability for use within Arizona. To accomplish this, you can utilize the Arizona eCorp Business Entity Search tool to determine if there are any existing registered business names in the state.

    During your search, it’s essential not only to verify that your exact business name is available but also to check for any similar names that could potentially lead to confusion or conflicts.

    Website Domain Search

    In today’s digital era, it’s vital for most businesses to have a robust online presence. Even if you do not have immediate plans to create a website, it’s advisable to check if the .com version of your business name is accessible. While there are other domain extensions available, .com remains the most popular and recognizable choice for businesses.

    By ensuring that the .com version of your business name is obtainable, you can establish a consistent brand identity across various online platforms and be ready for future website development.

    When you register the .com version of your business name through ZenBusiness, you can secure affordable protection against others using the same website name. Take action now to safeguard your brand identity.

    Taking the time to conduct thorough searches on business name availability will help prevent legal complications and allow you to establish a strong and distinctive brand identity in Arizona. 

    Once you confirm that your desired business name is available and not already in use, you can confidently proceed with registering your company and embarking on your entrepreneurial journey.

    Step 4: Form Your Business With the State of Arizona

    Once you have determined the structure of your business and chosen a name, the subsequent task is to register your business with the state of Arizona officially.

    For Arizona LLC Registration:

    In order to form your Arizona LLC, you’re required to present the “Articles of Organization” to the Arizona Corporation Commission. This can be accomplished through online submission, mailing, or in-person delivery.

    For Arizona Corporation Registration:

    When establishing an Arizona corporation, submit the “Articles of Incorporation” to the Arizona Corporation Commission.

    Protect Your Business Name With a Trademark

    After confirming the availability of your business name and securing it, you may want to apply for a trademark to protect your brand. The registration fee for a trademark typically ranges from $225 to $400, in addition to any attorney fees, and requires renewal every 10 years.

    While this cost may be high for new or small businesses, it offers nationwide protection under federal law. This ensures that you will have legal precedence if other companies attempt to use a similar name for their own business. In the case of local operations, many small businesses may not find a trademark necessary unless they have plans for national expansion.

    How to File an Arizona Fictitious Name – DBA?

    To register a fictitious name in Arizona, which is also referred to as a “Doing Business As” (DBA) name, you can adhere to the following instructions:

    1. Create an original and distinctive Doing Business As (DBA) name for your enterprise.
    2. Verify the availability of your chosen DBA name through a name search.
    3. Access the Trade Name Application form from the official Arizona Corporation Commission website.
    4. Duly fill out the Trade Name Application with all necessary details.
    5. Arrange for the application to be notarized.
    6. Submit the notarized Trade Name Application, along with the requisite filing fee, either by mail or in-person to the Arizona Corporation Commission.
    7. Await the processing and approval of your application.
    8. Upon approval, you will receive a certificate confirming the successful registration of your chosen fictitious business name.

    Remember that the procedure may vary based on your company’s classification and local laws. It’s always wise to verify with the Arizona Corporation Commission or consult a lawyer if necessary.

    How to Change the Name of an Arizona Business?

    If you desire to alter the title of your company in Arizona, there are two approaches available.

    Filing for a Trade Name (DBA Name):

    A convenient method for conducting business under a different name without altering the legal name involves applying for a Trade Name, commonly referred to as a “Doing Business As” (DBA) name. 

    By obtaining a DBA name, sole proprietorships and general partnerships can adopt an alternate business identity. Even Limited Liability Companies (LLCs) and corporations can utilize a DBA name, eliminating the need to submit an amendment and simplifying their business operations. 

    This enables them to operate using brand names that do not include the mandatory “LLC” or “Inc.” suffix present in their legal entity’s official designation.

    Filing an Amendment to the Legal Name:

    If you desire to alter the legal name of your LLC or corporation officially, the appropriate action to take is to file an amendment for the existing business name.

    To accomplish this, you will need to complete and submit the necessary forms (Articles of Amendment for LLCs and Articles of Amendment for corporations) along with a $25 filing fee. These documents should be sent via mail.

    Business Name Registration Laws in Arizona 

    The regulations governing the registration of business names for Limited Liability Companies (LLCs) in Arizona are outlined below.

    Business Name Search: Before officially registering a business name in Arizona, conduct a thorough search to verify its availability and confirm that it’s not already in use by another entity. To check the name’s availability, you can search the Arizona Corporation Commission (ACC) website.

    Entity Types: Arizona provides various options for business entity types, including sole proprietorships, partnerships, corporations, Limited Liability Companies (LLCs), and others. Each entity type comes with distinct registration requirements and legal implications, so it’s vital to select the one that aligns best with your business’s specific needs.

    Registration With the Arizona Corporation Commission: If you intend to operate your business as a corporation, LLC, or limited partnership, you must complete the registration process with the Arizona Corporation Commission (ACC). The ACC is responsible for overseeing business entities and managing their official records.

    Fictitious Name (Doing Business As – DBA): If your business conducts operations under a name that differs from the owner’s legal name, you will be required to register a “Doing Business As” (DBA) or “Trade Name” with the county where your business is located. This registration allows customers to recognize your business under its operational name.

    Trademark Considerations: It’s important to note that registering a business name with the ACC doesn’t grant trademark protection. If you seek exclusive rights to your business name across the state, consider pursuing trademark registration through the United States Patent and Trademark Office (USPTO).

    Professional Licensing: Certain businesses, particularly those operating in fields like medicine, law, or other professional domains, may need additional licenses or certifications to conduct business in Arizona legally.

    Remember that laws and regulations are subject to change, confirm this information with the Arizona Corporation Commission or consult a legal professional for the most current and precise details before registering a business name in Arizona.
