STEP 5: Submit the completed applicable compliance reporting materials in Verify.

Login to the Verify System through the CDX portal: Central Data Exchange (CDX)

Submit the completed applicable compliance reporting materials by the required deadlines.

Within a few minutes of all submissions, the submitter will receive a notification in their CDX inbox indicating whether the submission was accepted or rejected.
