Hello Larry,

I think the closest thing we could provide to what you’re looking for is the ontology source file we use to display information about the NDDF ontology in BioPortal.  The file is available (in RDF Turtle format) for download via our REST API:

Our REST API is documented here:

To use the API, you need an API key which requires that you register for an account on the BioPortal website (  Once you’ve registered for an account, your API key is displayed on your user account page.

Hope that helps.

I was wondering if you could help us.  We are looking for some National Drug Codes that are currently not contained in the list handled by the FDA or the available archived list.  After doing some searches we came across your site which seems to contain a good portion of the NDCs that we are missing.

For example we were able to find the 62991115603 NDC in the National Drug Data File portion of your portal (resulting link below).  I was wondering if you would be able to provide us with a file containing information with all the NDCs and Preferred Names in your system.

Example Link with needed information:

Thank you for your time.
