A "Name Mismatch" error in KYC is usually a formatting issue. When resubmitting your application on the Binance Official Website or the Binance Official App, carefully compare your input with your physical ID document. For region-switching help, refer to the Binance App Download page. Below are the specific causes and solutions.
Chinese Name vs. Pinyin
Binance KYC forms usually expect Pinyin for Chinese IDs.
| Incorrect Format | Correct Format |
|---|---|
| 张三 (Chinese) | ZHANG SAN |
| 李 四 (Space in Chinese) | LI SI |
| Zhang San (Mixed case) | Acceptable, but ALL CAPS is safest. |
The OCR system automatically converts Chinese characters from your ID to Pinyin for comparison. If you manually enter Chinese characters, it may trigger a mismatch.
Handling Compound Surnames
| Compound Surname | Pinyin |
|---|---|
| 欧阳 (Ouyang) | OUYANG |
| 司马 (Sima) | SIMA |
| 上官 (Shangguan) | SHANGGUAN |
Compound surnames should be written as one word without spaces.
Spacing in Pinyin Names
| Chinese Name | Correct Pinyin |
|---|---|
| 张三 (Zhang San) | ZHANG SAN (One space between Last and First name) |
| 张三丰 (Zhang Sanfeng) | ZHANG SANFENG (Given names written together) |
| 王小明 (Wang Xiaoming) | WANG XIAOMING (Given names written together) |
| 王 小 明 (Incorrect) | Do not add spaces between every syllable. |
The Binance OCR engine separates the Surname and Given Name. Only include a space between the Surname and the Given Name.
Rare Characters
Rare characters on an ID card may be misidentified by OCR. For example:
- Characters with many strokes.
- Rare or ancient surnames.
If the OCR misidentifies a character, contact live support after resubmitting to request a manual review. Provide a clear photo of your ID along with the correct Pinyin and an explanation.
IDs from HK, Macau, and Taiwan
| Document | How to Fill in KYC |
|---|---|
| HKID | Use the English name as shown on the document. |
| Macau ID | Use the English name as shown on the document. |
| Taiwan ID | Try Chinese or Pinyin based on the system prompts. |
Filling in the name exactly as it appears in the English/Latin script on your ID is the most reliable method.
Capitalization
| Format | Result |
|---|---|
| ZHANG SAN | ✅ Safest |
| Zhang San | ✅ Usually accepted |
| zhang san | ⚠️ Occasionally fails |
| zHaNg sAn | ❌ High failure rate |
For beginners, using ALL UPPERCASE is the best practice.
Middle Names and English Names
If your passport lists a name like "ZHANG SAN MEILI" (including an English name):
- Fill it in exactly as it appears on the passport.
- Do not follow your ID card if it differs from the passport.
Binance verifies you against the specific document you submit. Do not mix information from different documents.
Handling OCR Errors
Sometimes, after scanning an ID, the system only recognizes part of a name (e.g., only the first two characters of a long name):
- Save a screenshot of the system's incorrect recognition.
- When appealing, provide the original, high-quality ID photo.
- Customer support will manually correct the entry.
First Name vs. Last Name
The Binance form typically has two fields:
- First Name / Given Name: Your "given" name (e.g., SAN).
- Last Name / Surname / Family Name: Your "family" name (e.g., ZHANG).
Example: "Zhang San"
- Last Name: ZHANG
- First Name: SAN
Example: "Ouyang Feng"
- Last Name: OUYANG
- First Name: FENG
What If I Already Filled It in Wrong?
Changing your name after KYC approval is extremely difficult. If your KYC hasn't passed yet:
- Do not resubmit immediately with the same error.
- Wait for the rejection notice (if there is an error, it will be rejected).
- Fill it in correctly upon resubmission.
If your KYC is already approved but your name is misspelled:
- Contact customer support for an appeal.
- Upload a high-quality photo of your ID.
- Clearly state the correct spelling.
- Expect a processing time of 7–15 days.
Common Error Cases
| Case | Error |
|---|---|
| Sun Z. (Initials) | Must use your full legal name. |
| Mixed ZHANG 三 | Must be consistent (all Pinyin or all characters as per prompt). |
| Missing middle character | Must include every character of your name. |
| Wrong gender | Ensure the gender field matches your ID. |
Different Field Names
| English | Chinese Equivalent |
|---|---|
| Surname / Last Name / Family Name | 姓 (Xing) |
| Given Name / First Name | 名 (Ming) |
| Middle Name | 中间名 |
| Full Name | 全名 |
Minor Variations
The Binance system is usually tolerant of:
- Case differences (ZHANG vs Zhang).
- A missing single space in a name.
- A single typo in Pinyin (in some cases).
However, major character errors (e.g., ZHANG vs ZHENG) will always result in rejection.
FAQ
Q: How do I fill in a name with a dot (separator) like "Yimin·Abudula"?
A: Usually, replace the dot with a space: "YIMIN ABUDULA".
Q: Can I use my common English nickname (e.g., Mike Wang)?
A: No. You must use the exact Pinyin or English name as it appears on your legal ID.
Q: What if the name on my ID differs from my Hukou (Household Register)?
A: Always use the ID card. Binance verifies against the ID document you provide.
Q: My passport has my name before I was married, but I've changed it since.
A: Use the name exactly as it appears on the document you are submitting. Once the document is updated, you can update your Binance profile.
