There are several reasons why your verification could be rejected: 

  • low-quality photos;
  • documents that do not meet the requirements;
  • security reasons;

If the document review was rejected, you can see the specific reason for rejection on the "Verification" page.
In some cases, you can try to pass the verification again, on the Verification page, click "Try again" or "Upload documents".

Please note that documents can be uploaded in the required form and do not send too many incorrect files - this will lead to account blocking.
You can check all the documents requirements in the article "Verification process"
