Secretary of State Business Search Directory for All 50 States

Editorial Note: The content of this article is based on the author's opinions and recommendations alone. It may not have been reviewed, commissioned or otherwise endorsed by any of our network partners.

Secretary of state offices typically process and maintain the records for corporations, limited liability companies (LLCs) and partnerships in that state. If you’re interested in starting a business, this is one of the first places you’ll look to see if similar company names already exist and start the registration process.

Or, if you’re thinking about supporting or working with a business, a secretary of state business search on the respective websites can help you discover if the company is legitimate and in good standing. To save you time, we’ve rounded up websites for all 50 states and the District of Columbia so you can easily find the forms you need.

3 reasons to conduct a secretary of state business search

Here  are three main reasons to seek out your secretary of state’s website.

1.  Search for available business names 

Before you spend a lot of time and money to brand your business around a particular name, you need to be sure that name hasn’t been taken by someone else. Most secretary of state websites provide a name availability function. By typing in the desired name, you can discover if it’s still available or not. If it is, many secretary of state websites allow you to reserve the business name online. This allows business owners to claim a name while they gather paperwork necessary to go through the full registration process.

Registration requirements

Requirements vary depending on your business entity, but you’ll probably need to at least provide: names of the principal(s), registered agent and manager, plus the business name, address and duration.

2. Register your business

After confirming that the desired business name is available, you may be able to register your business online though some states require (or allow) applications by mail and in person. If you’re apprehensive about taking this step, many secretary of state websites provide step-by-step instructions. And since registering your company is just one step in starting a business, states may also provide next steps such as registering with your state’s department of revenue or labor department. It’s also a good idea to apply for your federal Employer Identification Number (EIN), which you’ll need to file your federal taxes.

3. Learn more about an existing business

Even if you’ve already formed your own company, a secretary of state business search can help you learn more about other companies. You may be thinking of a business-to-business relationship in which you buy from or sell to another company. If you’re considering contracting or subcontracting work, it’s important to know if the company is in good standing, including whether it’s current on its taxes or annual filings. These may be indicators of a company’s overall health.

Limitations of a secretary of state business search

Although secretary of state business searches can provide a wealth of information, they may not be helpful in every situation. That’s because not every type of business is required to register with the secretary of state. While the business search can locate most corporations, LLCs and partnerships, certain entity types — such as sole proprietorships — would not be included in a secretary of state’s database. That’s because these types of entities typically don’t have to register with their state government.

As a result, that company may instead be registered as a “doing business as” or DBA with its local government, so don’t automatically assume that a name is available for you to use before conducting a thorough search. Some secretaries of state maintain DBA databases, but in other states, that would be the job of a city or county clerk.
