    4 Steps to Register Your Business Name in Arizona

    Embarking on your entrepreneurial journey in Arizona requires an essential step – registering your business name in the Copper State. To guide you through this process, we’ve outlined four simple steps to ensure your business name is officially recognized in Arizona:

    Step 1: Choose Your Business Structure in Arizona

    The initial and critical decision you must make is selecting the appropriate business structure for your venture. The chosen structure will have significant implications for your business, including liability, taxation, and management. Here are the main options available in Arizona:

    Sole Proprietorship

    A sole proprietorship is the simplest form of business in Arizona. It involves a single owner who is legally considered the same entity as the business. While easy to set up, keep in mind that the owner is personally responsible for all business debts and obligations. Registering with the state isn’t mandatory for sole proprietorships, but you may need local permits or licenses.

    General Partnership

    If you’re starting a business with one or more partners, a general partnership might be suitable. In this structure, all partners share the profits and losses of the business. Like a sole proprietorship, a general partnership does not require state-level registration, but you may need to file a “Certificate of Registration” (DBA) with the county where your business operates.

    Limited Partnership (LP)

    A limited partnership consists of general partners who have unlimited personal liability and limited partners who enjoy limited liability but are not actively involved in managing the business. To establish an LP in Arizona, you must file a “Certificate of Limited Partnership” with the Arizona Corporation Commission.

    Limited Liability Company (LLC)

    An LLC is a popular choice for many businesses due to its flexibility and liability protection. It combines the advantages of a corporation (limited liability) with the simplicity of a partnership. To create an LLC in Arizona, you’ll need to file “Articles of Organization” with the Arizona Corporation Commission and develop an Operating Agreement outlining the company’s management and ownership structure.


    A corporation is a separate legal entity from its owners (shareholders) and offers limited liability protection. Arizona provides two types of corporations: C-corporations and S-corporations.

    To establish a corporation, you must file “Articles of Incorporation” with the Arizona Corporation Commission, depending on the specific type of corporation you choose. Corporations typically have more formal requirements, such as creating bylaws, issuing stock, and conducting regular board and shareholder meetings.

    Choosing the right business structure in Arizona is crucial, as it will impact the legal and financial aspects of your business. It’s advisable to consult with a legal or business professional to ensure you make the most suitable choice based on your specific needs and circumstances.

    By following these essential steps and making informed decisions about your business structure, you will successfully register your business name in Arizona and establish a strong foundation for your enterprise’s growth and success.

    Step 2: Select a Unique Business Name in Arizona 

    Selecting a unique and suitable name is a crucial part of establishing your brand identity. Moving on, we will explore the three ways you can name your business in Arizona and the necessary steps to protect your chosen name:

    When registering your business in Arizona, you must choose a legal entity name. This name is used by the state to identify your company and must be unique to avoid any potential conflicts with other businesses. Additionally, Arizona’s naming laws specify that the name should accurately reflect the type of business you’re operating. To ensure your desired name is available, you can check the Arizona Corporation Commission’s eCorp database.

    To protect your legal entity name, you must register it according to the business structure you selected in Step 1. Whether you’re forming an LLC, Corporation, or any other entity, securing your unique name is essential to establish your brand presence.


    Consider safeguarding your business name or logo at a national level by obtaining a trademark. A trademark is a valuable form of intellectual property protection that prevents others from using a similar name or logo for similar goods or services. Before proceeding with your desired name, conduct a thorough trademark search in the USPTO database to ensure no one else has registered a similar mark.

    While a trademark provides nationwide protection, keep in mind that it does not automatically grant you the right to use the name or logo in all circumstances. If you’re planning to expand your business beyond Arizona’s borders, a trademark is a powerful tool to secure your brand identity.

    Doing Business As (DBA) Name

    In Arizona, you have the option to register your business under an official name and operate using a different one. This alternate name is known as a Doing Business As (DBA) name or a trade name. Unlike the legal entity name, a DBA isn’t required to be unique at the state level. To register a DBA name, file a “Trade Name Registration” with the Arizona Secretary of State’s office.

    While DBA names are subject to federal trademark laws, they offer flexibility if you plan to run multiple businesses under different names or wish to rebrand without changing your legal entity name.

    Protecting Your Brand Identity:

    By considering these naming options and following the proper registration procedures, you can confidently establish your business name in Arizona and safeguard your brand identity. Remember, choosing a unique name in Arizona is vital for building a strong brand presence and gaining recognition among your customers and competitors.

    Before finalizing your business name, take the time to research and ensure its availability, both at the state level (for the legal entity name) and nationally (for trademarks). By doing so, you’ll pave the way for a successful and distinctive business venture in the thriving landscape of Arizona’s business community.

    Step 3: Check Business Name Availability in Arizona

    Before finalizing your business name and registering your company in Arizona, it’s essential to ensure that the name you desire is available and not already in use by another business. To conduct a thorough business name availability search, follow these three crucial steps:

    Begin by conducting a federal trademark search to check if your preferred business name is already trademarked. Trademarks are registered at the federal level and take precedence over state-level registrations. To perform a federal trademark search, visit the U.S. Patent and Trademark Office (USPTO) website and use their TESS Search tool.

    Verifying that your name isn’t trademarked is crucial to avoid legal disputes and potential rebranding efforts. If you find that your desired name is already trademarked, you will need to come up with an alternative business name.

    After ensuring that your business name isn’t trademarked, it’s time to verify its availability for use specifically within Arizona. To do this, utilize the Arizona eCorp Business Entity Search tool to check for registered business names in the state.

    In your search, not only confirm the availability of your exact business name but also check for any significantly similar business names that could potentially cause confusion or conflicts.

    In today’s digital age, having a strong online presence is crucial for most businesses. Even if you don’t plan to build a website immediately, it’s wise to check if the .com version of your business name is available. While other domain extensions are available, .com remains the most popular and recognizable for businesses.

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

    Registering the .com version of your business name with ZenBusiness ensures affordable protection from others using the same website name. Act now to safeguard your brand identity.

    Taking the time to conduct these thorough business name availability searches will help you avoid legal complications and establish a strong and unique brand identity in Arizona. Once you confirm that your desired business name is available and not already in use, you can proceed with confidence to register your company and embark on your entrepreneurial journey.

    Step 4: Form Your Business With the State of Arizona

    After finalizing your business structure and selecting a name, the next step is to formally register your business with the State of Arizona.

    For Arizona LLC Registration:

    To establish your Arizona LLC, you must submit the “Articles of Organization” to the Arizona Corporation Commission. This can be done online, by mail, or in person.

    For Arizona Corporation Registration:

    If you’re forming an Arizona corporation, you need to file the “Articles of Incorporation” with the Arizona Corporation Commission.

    Protect Your Business Name With a Trademark

    Once you have verified the availability of your business name and secured it, you might consider applying for a trademark to safeguard your brand. The trademark registration typically costs around $225 to $400, plus any attorney fees, and requires a renewal fee every 10 years.

    Although the cost might be steep for new or small businesses, it grants nationwide protection backed by federal law. This means you’ll have legal precedence if other companies attempt to use a similar name for their business. For many small businesses that operate locally, a trademark may not be necessary unless they plan to expand nationally.

    How to File an Arizona Fictitious Name – DBA?

    To file a fictitious name, also known as a “Doing Business As” (DBA) name, in Arizona, follow these steps:

    1. Choose a unique fictitious name (DBA) for your business
    2. Conduct a name search to ensure the chosen name is available
    3. Download or obtain the Trade Name Application form from the Arizona Corporation Commission’s website
    4. Complete the Trade Name Application with the required information
    5. Have the application notarized
    6. Submit the notarized Trade Name Application along with the filing fee to the Arizona Corporation Commission by mail or in person
    7. Wait for the application to be processed and approved
    8. Once approved, you will receive a certificate confirming the registration of your fictitious name

    Remember that the process might involve different requirements depending on your business entity type and local regulations. Always double-check with the Arizona Corporation Commission or seek legal advice if needed.

    How to Change the Name of an Arizona Business?

    If you wish to change the name of your business in Arizona, there are two methods:

    Filing for a Trade Name (DBA Name):

    The easiest way to operate your business under a different name without changing the legal name is to file for a Trade Name, also known as a “Doing Business As” (DBA) name.

    Sole proprietorships and general partnerships can use a DBA name to have an alternative business name.

    LLCs and corporations can also use a DBA name, avoiding the need to file an amendment and simplifying business operations. This allows them to operate with brand names that do not include the required “LLC” or “Inc.” suffix found in their legal name.

    Filing an Amendment to the Legal Name:

    If you wish to officially change the legal name of your LLC or corporation, filing an amendment to the existing business name is the appropriate course of action.

    For both options, the necessary forms (Articles of Amendment for LLCs and Articles of Amendment for corporations) must be completed and submitted along with a $25 filing fee, sent via mail.

    Business Name Registration Laws in Arizona 

    Business Name Registration Laws in Arizona for Limited Liability Companies (LLCs) are as follows:

    • Business Name Search: Before registering a business name in Arizona, it’s essential to conduct a thorough search to ensure that the desired name is available and not already in use by another entity. You can perform a name search on the Arizona Corporation Commission (ACC) website to check for name availability.
    • Entity Types: In Arizona, businesses can be registered as sole proprietorships, partnerships, corporations, Limited Liability Companies (LLCs), and other types of entities. Each entity type has different registration requirements and legal implications, so it’s essential to choose the one that best suits your business needs.
    • Registration With the Arizona Corporation Commission: If you plan to operate your business as a corporation, LLC, or limited partnership, you need to register with the Arizona Corporation Commission (ACC). The ACC is responsible for regulating business entities and maintaining their records.
    • Fictitious Name (DBA): If your business operates under a name that’s different from the owner’s legal name, you will need to register a “Doing Business As” (DBA) or “Trade Name” with the county where your business is located. This allows customers to identify your business under its operating name.
    • Trademark Considerations: Registering a business name with the ACC does not provide trademark protection. If you want exclusive rights to your business name throughout the state, you may consider filing for a trademark with the United States Patent and Trademark Office (USPTO).
    • Professional Licensing: Some businesses, such as those in the medical, legal, or other professional fields, may require additional licenses or certifications before they can operate legally in Arizona.

    Please note that laws and regulations can change over time, so it’s essential to verify this information with the Arizona Corporation Commission or seek legal advice for the most up-to-date and accurate information before proceeding with business name registration in Arizona.
