deposit slip
Deposit Slip: the small paper or app form you fill to tell the bank exactly whose account should receive the cash or cheque you are paying in.
In plain English
Why does the bank still ask you to fill a slip when the cashier can clearly see the cash in your hand?
Because the money does not know where it is going until you write it down. The cashier can count your ₦50,000 all day, but unless someone links that cash to an account number, it just sits there as unclaimed paper. The deposit slip is the instruction that says, this money belongs to this account, put it there and nowhere else.
Think about the last time you paid money into a shop owner's account at a banking hall in Yaba, or helped your mother pay rent money into the landlord's account at the branch counter. You picked up a small slip, wrote the account number, the account name, the amount, maybe your phone number, and handed it over with the cash. That slip is the bank's proof of what you intended, and it becomes part of the paper trail if anyone ever asks where the money went.
In the United Kingdom, fewer people use paper slips now because most deposits happen through mobile apps or by transfer, but you will still find deposit slips at some bank branches and at cash machines that accept deposits, where you post the slip along with a cheque into an envelope slot.
The slip matters most when things go wrong. If the cashier keys in the wrong account number, the slip is the record everyone checks to see who made the mistake, you or the bank. Keep your stamped copy until the money shows in the receiving account, because that little paper is your receipt that the bank actually took your money in.
These days, many transactions skip the slip entirely through electronic banking, but the idea behind it, clear instruction plus proof, is still exactly what a transfer reference number does for you online.
Chidinma walks into a branch in Enugu with ₦120,000 cash to pay into her tailor's business account. She fills a deposit slip with the tailor's account number, account name, and the amount, hands it to the cashier with the cash, and gets back a stamped copy showing the transaction was received.
Questions people ask
Do I still need a deposit slip if I bank online?
Not usually. Online and mobile transfers generate their own reference number automatically, which does the same job the paper slip used to do, proving the money left one account and reached another.
What happens if I write the wrong account number on a deposit slip?
The cash may go into a stranger's account. Always double check the account name the bank displays before you hand over the slip and cash, because reversing a wrong deposit can take days or weeks.
Should I keep my stamped deposit slip after paying money in?
Yes, always. It is your proof that you paid, and if there is ever a dispute about whether the money arrived, that stamped slip is often the first thing the bank asks to see.
