Apply for proper business licensing with the license bureau of the state that the business resides or will reside in. You will need proof of licensure before you open a bank account with a DBA designation.
Determine what bank you want to open the bank account with. Many banks usually honor requirements to open a bank account with DBA, but it's advised to check first to confirm.
Decide which name you will use as your DBA name for the bank. This will generally be something that is similar to the original business' name or close in nature.
Give these items to the bank to open the DBA account: driver's license, business license and proof of Social Security number or an employer's identification number card.
Endorse all checks that go into the business account with your DBA name that is linked to the account.
Notify any other interested parties or financial institutes of your business' DBA status so that they may update their records.
