Here's the short answer: the safest thing to write in the Binance C2C transfer note field is nothing at all. If you must write something, avoid any word related to crypto, Binance, or the purpose of the transfer. Safe, generic wording like "none," "payment," "rent," or "loan" works. Once a note contains a flagged word, the odds of triggering bank risk controls go up significantly. Before you start, use the Binance Official Site to complete KYC; open the Official Binance App to handle C2C, and if you can't install it on iPhone, see our iOS install guide.
Bank risk-control systems scan the keywords in transfer notes. For a CNY 5,000 transfer, writing "USDT" versus writing "none" in the note produces wildly different odds of getting flagged. Here's a full breakdown of the banned-word list, recommended wording, and how banks scan transfers.
Every bank in mainland China is connected to an AML monitoring system that scans transfer notes for:
| Risk Level | Response |
|---|---|
| Level 1 (mild) | Logged internally, user not notified |
| Level 2 (moderate) | Reduced limits, extra verification steps |
| Level 3 (severe) | Temporary freeze, in-branch explanation required |
| Level 4 (critical) | Long-term freeze, reported to AML authorities |
A single mild trigger usually isn't a problem, but repeated triggers escalate over time. That's why you should avoid it every single time.
Avoid any form of crypto-related wording:
| Category | Specific Words |
|---|---|
| Coin names (English) | USDT, BTC, ETH, TRX, BNB |
| Coin names (Chinese) | Tether, Bitcoin, Ethereum, Tron |
| General terms | crypto, virtual currency, digital currency |
| English general terms | crypto, coin, token |
| Derived terms | token, stablecoin |
| Category | Specific Words |
|---|---|
| Platform names | Binance, Huobi, OKX, Coinbase |
| Platform romanizations | binance, huobi |
| Derived terms | exchange, CEX, DEX |
| Category | Specific Words |
|---|---|
| Buying/selling | buy coin, sell coin, top up, withdraw coin |
| Transfer-related | deposit, withdrawal, coin transfer |
| Investment-related | crypto investment, digital investment |
| Category | Specific Words |
|---|---|
| Chain | blockchain, ETH, TRC |
| Wallet | wallet |
| Mining | mining, mining pool |
| Contracts | futures, contract, perpetual |
Bank risk control can also detect disguised variants:
| Original Word | Common Variant | Still Detected |
|---|---|---|
| USDT | usdt, U, $U, U-S-D-T | Yes |
| Binance | bian, b-an, "b coin" | Yes |
| Bitcoin | btc, "b coin" | Yes |
Don't try to dodge detection with a variant spelling — it tends to look even more suspicious.
Leave the transfer note field completely empty. This is the safest option — banks don't flag you just for leaving it blank.
If you're required to enter something (some banking apps force a note field), you can write:
| Purpose Category | Specific Words |
|---|---|
| Living expenses | payment, living expenses, allowance, household goods |
| Rent | rent, deposit, property fee |
| Loans | loan, repayment, debt, lending |
| Salary | salary, wages, pay, compensation |
| Gifts | gift money, cash gift, birthday gift |
| Tuition | tuition, training fee, tutoring fee |
But keep it plausible — writing "salary" to a total stranger looks a bit odd. The most natural choices are "payment" or "loan," or simply leaving it blank.
Some merchants list "Note: please write 'payment'" on their order. Follow their instructions and write "payment" — it's a wording they've already tested as safe.
But watch out for a merchant asking you to write the exact USDT amount in the note. Never do this — report the merchant immediately.
| Bank | Risk-Control Strictness | Notes |
|---|---|---|
| China Merchants Bank | Strict | Strong keyword monitoring, high trigger rate |
| ICBC | Moderate | Mostly triggers on large amounts |
| China Construction Bank | Moderate | Same as above |
| Agricultural Bank of China | Moderate | Same as above |
| Bank of Communications | Moderate | Relatively balanced risk controls |
| China CITIC Bank | Moderate | Middle of the pack |
| Ping An Bank | Strict | Internet-finance background, strict risk controls |
| MYbank | Extremely strict | Alibaba-affiliated, very sensitive to crypto-related activity |
| WeBank | Extremely strict | Tencent-affiliated, same as above |
Internet-native banks tend to be stricter overall — mainland users are generally better off primarily using one of the "big four" state-owned banks (ICBC, CCB, ABC, BoC).
Plenty of new users write "3500U" or "100USDT" to help them track the transfer. This is the most serious mistake:
For example, "John — buying coins." This is a double violation:
For example, "Order 12345678." Seems harmless, but:
The order number already exists in Binance's own system — there's no need to include it in the note.
Any wording directly tied to crypto trading will trigger risk control without fail.
If a merchant tells you in chat to "write [some phrase]" in your note, don't blindly copy it — check whether that phrase contains a flagged word first.
Open your usual bank's mobile app (not online/web banking) — the note field on mobile apps is usually more lenient.
The whole process takes 2-3 minutes.
If your bank card gets flagged because of a transfer note:
Q: Do I have to write something in the note? Can it be blank? A: Yes, it can be blank. Most banking apps support an empty note. If a bank requires at least one character, write "none."
Q: The merchant wants me to write the USDT amount in the note — should I? A: No. That's either a scam or an unprofessional merchant. Switch merchants immediately.
Q: Won't writing "loan" make it look like an illegal lending transaction? A: No. "Loan" is an extremely common note — millions of legitimate lending transfers use this exact wording every month.
Q: Is it okay to write a friend's name as the note? A: Not recommended. Writing a friend's name on a transfer to a stranger is easy to flag for manual review. Leaving it blank is safest.
Q: What if I realize after the fact that I used a flagged word? A: Watch for 24 hours to see if you get flagged. If nothing happens, be more careful next time. If you do get flagged, follow the process above.
Q: Can I use a different note for each transfer when splitting a large purchase into several transfers? A: Yes. Leave each one blank, or use a different common word each time. But the same amount transferred repeatedly to the same merchant will draw attention regardless of what the note says.
The transfer note is one of the easiest details to overlook in C2C funding, but it carries real risk. The safest approach is to leave it blank — no keywords means no trigger. Check our Deposit Withdraw category for more C2C safety details.
