The core rule for C2C payment notes: Never write sensitive words like USDT/Binance/crypto—bank risk control systems automatically scan for these words and will freeze your account. Safe notes: Leave it blank / "loan" / "repayment" / "salary" / "gift money" and other neutral terms. Register an account from the Binance Official Site, download the APK from the Binance Official APP, and see the cross-platform process in the Download Center. This article provides complete guidelines for writing notes.
Why Are Notes So Important
Bank anti-money laundering systems will automatically scan transfer notes:
- Discovering sensitive words marks the account as "high risk"
- Triggering this multiple times will freeze the bank card
- In severe cases, the account may be permanently banned
One wrong note = your card could be frozen for 30 days to 6 months.

Note Rules for Different Payment Channels
Alipay
- The field is called "Note"
- Both receiver and sender can see it
- Bank statements will sync it
- Strongly avoid sensitive words
WeChat Pay
- The field is called "Add Note"
- Also visible and synced to bank statements
Bank Card Transfer
- The field is usually "Postscript" or "Message"
- Displayed on the receiver's bank card
- Recorded within the bank's internal system
Cloud QuickPass / Digital Currency
- Similar rules to the above
- Recorded by the bank system
No matter which channel, the rule is consistent: avoid sensitive words.
Will Merchants Ask for Specific Notes?
Legitimate merchants will not ask for specific notes:
- Merchants also know the risks of sensitive words
- Most will tell you to "leave blank" or "customize"
If a merchant asks you to write USDT, Binance, or other sensitive words:
- Refuse
- The merchant might be a scammer (trying to shift blame onto you)
- Or the merchant is unprofessional (you'll be implicated if things go wrong)
Consequences of a Wrong Note
Immediate Consequences
- Transfer completes (the note won't block the transfer itself)
- Bank system flags your card
After 1-3 Days
- Bank AML department reviews it
- They might contact you (call/SMS) to ask about the situation
After 7-30 Days
- If the review fails → your card gets frozen
- Depending on the situation, it could be unfrozen or face long-term freezing
Extreme Consequences
- Account permanently banned
- If involved in a case, it will face judicial investigation
The cost of one wrong note is far greater than taking a few seconds to fill it out properly.
Remedies for Writing a Wrong Note
If you accidentally wrote a sensitive word:
Immediate Action
- Cancel the transfer (if the payment platform allows)
- Re-initiate the transfer with the correct note
If the Transfer Has Completed
- Delete/modify the note (not possible on most platforms)
- Initiate a refund (ask the other party to return it)
- Transfer again with the correct note
If the other party has received the money and is unwilling to refund (C2C merchants will ask you to pay and won't refund), it is recommended to:
- Accept this small risk for now
- Strictly standardize notes in the future
- Monitor whether your bank card faces risk control
A single wrong note won't necessarily freeze your card immediately—but accumulating them multiple times will definitely cause issues.
The Risk of "Humorous" Notes
Some people try to be funny:
- "Buying some BTC to try" → Obviously a sensitive word combo
- "Investing in digital assets" → Same as above
- "Buying virtual goods online" → Triggers "virtual" + "buying"
Don't joke around—bank systems don't distinguish between a joke and true intent.
Note Strategies for Different Amounts
Small Amounts (< 1,000)
- You can use "loan", "repayment", etc.
- Bank risk control is relatively relaxed
Medium Amounts (1,000-10,000)
- Still use neutral words
- Keep notes as short as possible
Large Amounts (> 10,000)
- Notes must be extremely cautious
- Leaving it blank is highly recommended (allowed by most platforms)
- Or use a very short "salary"
Banks have stricter risk controls for large transfers, making notes more sensitive.
Notes When Receiving USDT
When selling USDT via C2C, the other party pays you. Your bank statement will show their note.
If the other party's note contains sensitive words:
- Even if you didn't write it, your card could still be risk-controlled
- Because banks review all notes in your statement
How to handle:
- Check the payment note when verifying receipt
- If it contains sensitive words → Refuse to release coins + Appeal
- Ask the other party to pay again using a compliant note
Alongside Standardized Notes
Standardizing notes is not enough; you must also coordinate with:
1. Use a Dedicated C2C Card
- Single card exclusively for this, keeping the impact scope controllable
2. Control Single-Transaction Amounts
- Single transaction ≤ 20,000
- Do not exceed daily limits
3. Reasonable Frequency
- Avoid multiple large transfers in a single day
- Prevent triggering "high-frequency risk control"
4. Transfer Out Immediately Upon Receipt
- Don't let money received from C2C sit for long periods
Only a complete set of safety practices can truly reduce risk.
Practical Note Examples
Buying USDT (You Pay the Merchant)
| Amount | Recommended Note |
|---|---|
| 700 | Leave blank or "Loan" |
| 5000 | "Salary" or "Bonus" |
| 20000 | "Service fee" or "Consulting fee" |
Selling USDT (Merchant Pays You)
If you can choose the other party's note (some merchants will ask):
- "Gift money"
- "Refund"
- "Support"
- Or leave blank
Notes for Overseas Channels
If you use an overseas bank account:
- Most overseas banks are not as strict as mainland China
- But important foreign currency transfers still face risk control
- SEPA / SWIFT transfers have a "Transfer Purpose" field, avoid sensitive words
International channels are more lenient, but caution is still advised.
Frequently Asked Questions
Q: Is it okay to leave the note blank? A: Yes. Most payment platforms allow blank notes. It is the safest choice.
Q: Can the bank see Alipay/WeChat notes? A: Yes. The transaction flow will sync to your bank account records.
Q: Can I use pinyin/English to bypass sensitive words? A: No. Bank systems recognize pinyin and English. "yousidi" is also recognized as USDT.
Q: Can I use emojis in the note? A: Usually yes, but some payment platforms filter special characters. Not recommended to rely on them.
Q: Is it reliable when a merchant says "writing USDT in the note gets you the money faster"? A: Not reliable. Such merchants might be scammers (trying to frame you). Change merchants.
Q: Will my card definitely be frozen if I write the wrong note? A: Not necessarily. A single mistake might be fine. A single mistake is much more dangerous when accumulated multiple times or during large transfers.
Summary
The core rule for C2C payment notes: Never write sensitive words like USDT/Binance/crypto/wallet/C2C—bank risk controls will automatically scan and trigger an account freeze. Safe notes: Leave blank / "loan" / "repayment" / "salary" / "gift money" and other neutral words. Rules across different payment channels (Alipay/WeChat/Bank card) are consistent—they all sync to bank statements. The cost of one wrong note (card frozen for 30 days to 6 months) far exceeds taking a few seconds to fill it carefully. Pair this with a dedicated C2C card + single transactions ≤ 20,000 + reasonable frequency + immediate transfer-out upon receipt to build a complete C2C safety system.
