If you don’t have business checks for your business bank account, there are alternative ways to verify your account. They include:
Letter from your bank: request an official letter from your bank confirming your account details on their letterhead.
Direct deposit form: if you have a direct deposit form for your business, it must include the bank's name, address, routing number, business name, and account number.
Counter-check: You’ll need to ask your bank to print this for you.
