A small detail that is easy to skip and can cause real trouble: the reference or memo line on the bank transfer you send for a P2P order. Some people like to spell out the purpose, writing something like USDT purchase, because it feels like tidy bookkeeping. For most payments that instinct is sound. For this one it tends to backfire.
Why one line of text can trigger a bank review
Banks screen payments automatically, and the reference field is part of what gets screened. Words tied to crypto, such as the name of a coin or an exchange, sit high on many banks' watch lists. When a reference matches, the least you can expect is a payment held or bounced for review; at worst the account gets restrictions until you explain yourself in person. You have effectively labeled the payment yourself, handing the bank's systems a signal they would otherwise have to infer from patterns.
It does not stop with you, either. The reference also appears on the seller's statement, so a seller who receives a payment marked as a crypto purchase gets flagged along with you. That makes this less a matter of personal caution than a basic courtesy of P2P trading, and it is why P2P platforms, Binance's included, remind buyers not to put crypto-related words in the payment remark.
What to write instead: usually nothing
An empty reference is the best reference. Many bank transfers do not require one at all. If your banking app insists on something, use whatever the P2P order page tells you to use; some merchants ask for part of the order number, for example. Follow the instructions shown on the platform's order page, not instructions that arrive in a chat message. If the page says nothing and your app still demands a reference, write something plain and true, such as your own name.
Two things not to do. Do not invent a purpose, such as rent, a loan, a gift, or an invoice number. A made-up reason is a false statement to your bank, and it becomes the one thing you cannot explain if the bank ever asks; an empty field needs no explanation, an invented one does. And do not use a code word someone gives you in the chat. Genuine trades do not need code words, and a trade that needs one is a trade to walk away from.
To be clear about what leaving it blank means: it is not hiding the payment. The transfer still goes from an account in your name to an account in theirs, fully visible to both banks. If either bank asks what the payment was for, tell them the truth: you bought USDT from a seller on a P2P platform, and here is the order.
When the merchant tells you what to write
Most merchants never mention the reference. When one does, what they ask for decides what you do:
- "Leave it blank" or "no notes, please." The most common request, and a good sign. Plenty of merchants put it in the terms of their ad, and you simply comply.
- "Put the last four digits of the order number." Some merchants use this to match payments. Check whether the order page itself says the same; if it does, type the digits and nothing else.
- A made-up purpose such as "rent" or "invoice 2291", or a code word. This is the one to walk away from. A seller who wants your payment to look like something else is usually protecting an account that is already in trouble, or moving money that is not theirs. Cancel the order and pick another merchant, even if you have already spent ten minutes chatting.
Watch for the pairing that gives the game away: the account you are asked to pay is in a different name from the verified name on the order, and the same person is coaching you on the reference. Either one alone is a reason to stop. Together they describe your money being used to pass someone else's through. The name on the order and the name on the receiving account must match; that check matters far more than any memo line, and our merchant guide covers the rest of what to look at.
Already sent it with the coin's name in the reference?
A sent reference cannot be edited, so there is nothing to fix on the payment itself. It also does not change what the payment is; it only makes it easier for a screening system to pick out. What you do next matters more:
- Let the order finish normally. If the money has reached the seller, let them confirm and release the coins. Do not ask for a private refund to "redo" the payment. A refund outside the order has no escrow behind it and adds a second transfer you would have to explain.
- Save the order the same day: the order details, the order chat, and your bank's confirmation of the payment. What the reference says matters much less than being able to show the complete order behind it; our guide to transaction records covers what to keep.
- If your bank asks, say what happened. You paid an individual seller for USDT through a P2P platform, and here is the order. A plain account with the order record attached is the fastest way to close a review; an invented explanation is what turns a routine question into a long one.
If the bank blocked or returned the transfer and the seller never received it, tell the seller in the order chat, cancel through the platform, and pay again on a fresh order with the reference left empty.
On the receiving end
When you sell, the buyer writes the reference and you cannot stop them. Two habits help. Say it up front, with a line in your ad terms or a message when the order opens asking buyers to leave the reference empty; most will. Then check what actually matters when the money lands: does the payer's name match the verified name on the order, and is the amount exact? A payment from a different name gets no coins, however clean its reference, and goes to the platform's appeal process. A payment with the right name and amount but a crypto word in the memo is still a good payment; complete the order and keep the records.
One kind of reference deserves a second look: a buyer who volunteers an unrelated purpose such as "loan repayment" or "goods". It does not prove the money is bad, but it does show someone dressing the payment up. Re-check the payer's name before releasing, and notice whether they are pushing you to hurry. If the funds do turn out to be tainted, our guide to receiving dirty money covers what to do.
Before you tap Send
| What you see | What to do |
|---|---|
| The reference field is optional | Leave it empty |
| Your app will not send without one | Your own name, nothing else |
| The order page asks for the order number | The digits only |
| The merchant suggests a purpose or a code word | Cancel and choose another merchant |
| The receiving account is in a different name from the order | Do not pay; cancel or appeal through the platform |
Where your real proof lives
A common worry: with the reference left empty, how do you show later what the payment was for? The proof was never going to be in the reference. The platform's order record is the complete receipt: amount, counterparty, time, and unit price, and it lines up with your bank statement on both amount and time. Keeping those orders organized, as described in our guide to transaction records, is worth far more than anything you could type into a memo line. The ordering and payment steps themselves are in our guide to buying USDT on P2P.
The reference line is the smallest habit in moving money safely. Choosing the right counterparty, covered in our merchant guide, sticking to escrow, and keeping records do most of the work. But this one costs nothing at all, because the right move is to do nothing, which makes it the easiest mistake to avoid.
