Deposit slip
The pre-printed form, often found at the back of a checkbook, used to deposit cash or checks into your account; it lists your account information and a routing number. It is sometimes offered as a substitute for a voided check, but it is the least reliable option: the routing number printed on a deposit slip is sometimes an internal, deposit-only number that differs from the ACH routing number used for electronic transfers, so using it for direct deposit can misroute the payment. Many payroll and benefit systems specifically ask for a check rather than a slip for this reason — only rely on a deposit slip if the recipient explicitly accepts one.

Voided check vs. deposit slip vs. bank letter
A voided check is the most widely accepted proof of account because it shows your name plus the routing and account numbers payroll needs. A bank verification letter is the strongest formal alternative; a deposit slip is weakest, because its printed routing number can differ from the one used for electronic transfers.
How to find your routing and account number
Your nine-digit routing number is the left-most number along the bottom of a check, followed by your account number and then the check number. You can also find both in your bank's app or website under account details, and on a statement. Use the ACH routing number for direct deposit, not a wire one.
What the numbers on a check mean
The numbers along the bottom of a check, called the MICR line, read left to right as three groups: the nine-digit routing number that identifies your bank, your account number, and the check number. The symbols between them are field separators, and the line is printed in magnetic ink so machines can read it.
