CDX / CEDRI Registration Process

Submittal of files through CDX requires a CROMERR compliant signature (What is CROMERR?). Authorized signature authorities for the facility should use the LexisNexis electronic identity validation service in lieu of a paper based validation. If the signature authority chooses to use the paper based validation process, the CDX Reporting Center will request the phone number of the signature authority’s employer/authorizing official to verify employment.

Facility contractors (consultants) must proceed through the paper based validation process prior to submitting files to CDX. Contractors should not use the LexisNexis electronic signature authority validation process in lieu of the paper based validation process. During the validation process, the CDX Reporting Center will request the phone number of an authorized official of the facility on behalf of which the files are submitted. The CDX Reporting Center will contact the authorized official to verify that the contractor is authorized to submit data on behalf of the company.
