Accreditation and Reaccreditation Waiver Has Been Lifted

The waiver of accreditation and reaccreditation requirements has been lifted.  The NSC has resumed its validation that newly enrolling suppliers meet the accreditation requirements.  Further instructions will be provided for suppliers that were newly enrolled under the COVID-19 accreditation waiver without obtaining the appropriate accreditation. 


For enrollment related questions, please contact the NSC at or 866-238-9652 from 9 a.m. until 5 p.m. ET.
