Visit or call your bank's customer service center to amend your checking account information.
Tell the bank that you want to add a business name (also called a "DBA") to your account so that you can deposit checks made out to your small business.
Provide your Social Security number or tax ID number, government-issued ID and checking account number.
Submit a copy of your business license, fictitious business name certificate or certificate of trade name as proof that you own the business to be added to your account.
Write the business name on the back of the check (called endorsing) and make sure it matches the business name on your account and the name to whom the check is made payable.
Write the account number of your checking account, if applicable (some banks recommend that you write the account number for deposit). Complete a deposit slip if applicable (depending on bank policies).
Submit the endorsed check and deposit slip to a bank teller or ATM (depending on your bank policies and your account).
