# Duplicate Request Detection

### Duplicate Request Prevention

The system automatically flags and blocks duplicate ID Verification requests to ensure data integrity.\
![](/files/DeqIxLOUDtFzkxB0Twk0)

If a duplicate is detected:

1. The system will notify you that the request already exists.
2. Action: You must delete the line to remove the blocked duplicate submission.
3. To Resend: Use the dedicated Resend functionality for existing subjects instead of submitting a new request.

For questions regarding a blocked duplicate, please contact Customer Success at <orders@vcheckglobal.com>.
