The NDC Registry lists all companies that are successfully certified as either NDC-Certified or NDC-Capable, in accordance with the IATA Guide to the NDC Certification Program (pdf).
PLEASE NOTE: The NDC-Certified and NDC-Capable designations do not validate the content of the designated entity’s messages and do not entail any kind of certification, validation or endorsement of (i) any aspect of the entity, (ii) the quality or other aspects of its activities or products or XML API, (iii) any commercial products that may be derived from the usage of validated NDC messages or the XML API.
Thank you for your interest in NDC and ONE Order certification programs. Please note that, as of 1 November 2022, participants have completed transition to the Airline Retailing Maturity (ARM) index program. Please see the new ARM index registry and information on the ARM index program.
