Welcome to the CDR Online Credential Verification System!

The on-line verification system serves as a primary source verification of credentials issued by the CDR and is consistent with The Joint Commission Standards for primary source verification.

It is the responsibility of the user to confirm the correct identity of the individual whose credentials are being verified on this on-line system to avoid confusion between two individuals with similar names. 

The CDR on-line verification system will provide credentialed verification for:  Registered Dietitian Nutritionist (RDN) or Registered Dietitian (RD); Nutrition and Dietetics Technician, Registered (NDTR) or Dietetic Technician, Registered (DTR); Board Certified Specialist in Pediatric Nutrition (CSP); Board Certified Specialist in Renal Nutrition (CSR); Board Certified Specialist in Sports Dietetics (CSSD); Board Certified Specialist in Gerontological Nutrition (CSG); Board Certified Specialist in Oncology Nutrition (CSO); Board Certified Specialist in Obesity and Weight Management (CSOWM); Advanced Practice Certification in Clinical Nutrition (AP).

To search the on-line verification system, the user must enter the CDR issued registration identification number and the credentialed practitioner's primary state of residence. Although the CDR database may reflect both a primary and a secondary address, this system will only search the database using the primary address. If the state of residence does not match the primary address in the database, you will receive a message indicating "the state does not match primary address." You should contact the CDR office at 1/800-877-1600 extension 5500, to resolve this issue before taking any action. 

In cases in which a practitioner is using a credential that cannot be verified, and is thus engaged 'misuse' of a CDR issued credential, the user can e-mail CDR at creidy@eatright.org. 

RDNs or RDs who are applying for Pennsylvania State Licensure should not use the CDR online verification system to complete their licensure application.  Please contact CDR at 800/877-1600, ext. 5500 or by e-mail at cdrverify@eatright.org to request the Pennsylvania Licensure Verification Certificate.

Attention Licensure Boards and Employers: CDR has developed a web-based method for licensure boards and employers to verify credentialed status for credentialed practitioners. For more information click here.  Please note that disciplinary action cannot be verified using this system.  Please send those requests to knowledge@eatright.org.
