Research the procedure for registering a DBA in your state. Many states require you to register your DBA with either a division of the secretary of state's office, such as the division of corporations, or with a clerk of the court.
Select a DBA that is not already in use. Most states have an online, searchable database of the names already registered. In addition, make sure your name doesn't end in a corporation or LLC suffix, such as "Big Corp.," "Landing Pad, Inc." or "Flying High, LLC."
Complete the DBA registration form. This form usually requires the business owners' names and addresses, business's purpose, business's address, and its registered agent's name and address. Some states may also require you to have the form notarized.
Submit the registration form to the appropriate governing body. In some states, this is the secretary of state, while in others, it might be the local clerk of the court. Generally, you must pay a fee when registering your DBA, which varies from state to state.
Publish notice of your new DBA in a publication of general circulation, if required by your state. For example, California requires that within 30 days of filing, you must publish a statement in a newspaper in the county where you have your principal place of business once a week for four weeks.
Register the DBA in every locality where you will use the name, if required by your state. For example, Virginia requires you to register your name in each county you will do business.
