# Common Reasons for KYC Verification Failure

When completing Identity Verification (KYC), your submission may fail for several common reasons. Below are the most frequent issues and how to resolve them.

***

1. ### **Blurry or Unclear Document Photos**

     Verification may fail if:

   * The image is blurry, overexposed, or too dark
   * Key information cannot be recognized
   * The document is cropped or partially visible

     **Tip:** Ensure good lighting and upload a complete, clear, and unedited photo of your document.

***

2. ### **Incorrect Document Type**

     Your submission may be rejected if:

   * You uploaded a document type that the platform does not support
   * The document is expired

     **Tip:** Submit a valid government-issued ID, passport, or driver’s license that meets the platform requirements.

***

3. ### **Mismatched Information**

     Failures often occur when:

   * Your name, date of birth, or ID number is entered incorrectly
   * The details do not match the information on your document

     **Tip:** Double-check that all entered information matches your ID exactly.

***

4. ### **Facial Recognition Failed**

     This may happen when:

   * The environment is too dark
   * Your face is partially covered
   * Your appearance differs greatly from your ID photo

     **Tip:** Remove hats, glasses, or masks, face the camera directly, and complete the process in a well-lit environment.

***

5. ### **Document Already Used or Flagged as Risky**

     Issues may arise if:

   * The same document has been used for other accounts
   * The system detects suspicious or abnormal behavior

     **Tip:** Make sure you are using your **own** document and avoid registering multiple accounts.

***

6. ### **Network or Upload Errors**

     KYC may fail if:

   * Images did not upload successfully
   * The network disconnected during submission

     **Tip:** Use a stable network connection and resubmit your verification materials.
