For CUSIP use Bloomberg:

For D-U-N-S Numbers use Hoover's Online:

  1. Click on Build A List.
  2. Scroll down to Company Information and click on the + to expand the list.
  3. You can upload a file of D-U-N-S numbers or search by individual number.

For GVKEY use Compustat. This database has defined a proprietary identifier, the GVKEY, which can be used to track a company over time (a company name, CUSIP, or ticker may change over time).
