Researching Business Name Availability

Your business name is one of the most important aspects in starting a business. The name you choose will represent the image and label of your business, and you want that image conveyed clearly to your customers. In addition, thought must be given to making sure you do not infringe upon the rights of someone else's business name.

Researching the Availability of a Business Name

Because trade names are not legally required to be registered in Arizona, making sure your business name does not infringe on an existing business name - whether it is registered or not - involves research on your part. Begin your search by using the Arizona Secretary of State Entity Search and the Arizona Corporation Commission Search for an Entity Name. Please note: The Arizona Secretary of State only approves a name as being distinguishable from other names already on file with the Secretary of State and the Arizona Corporation Commission.

It is a good idea to also search other places, such as the Internet, phone book, industry associations, etc. to try to eliminate the chance that someone else is using the name. If others are using the name, you may incur legal consequences if you use the same or very similar name. Consult an attorney to find out the legal consequences of using a name that is owned by or used by others. (23)
