Abbreviated New Drug Application (ANDA) Forms and Submission Requirements

This page is a content and format information resource for the generic drug applicants on information on ANDA submission requirements.

ANDA Forms and Electronic Submissions

Requesting a Pre-Assigned ANDA Number

  • Step-by-step description of how to request a pre-assigned ANDA number from OGD.
  • You may request a pre-assigned number, ONLY when you are submitting a NEW ANDA. If you are converting an established ANDA to eCTD, you MUST use the original ANDA application number.
  • If you have any comments or questions, please email CDERAPPNUMREQUEST@fda.hhs.gov.


  • For paper submissions, postal carrier packages MUST be addressed to the document room (include “ATTN: DOCUMENT ROOM” in the address label) in order for the submission to be processed and tracked. Failure to do so will delay the reviewer’s receipt and review of submission. Please send all submissions (original ANDAs, ANDA amendments, ANDA supplements, and ANDA resubmissions) to the OGD document room address below:
Office of Generic Drugs
Center for Drug Evaluation and Research
Food and Drug Administration
Metro Park North VII
7620 Standish Place
Rockville, MD 20855

Hours of Operation: Monday thru Friday 7:00AM - 6:00PM
Note: We highly recommend that firms consider submitting documents in electronic format.  The OGD document room has limited space and resources to maintain paper documents.
  • For the submission of Form FDA 3500A reports (15-day Alert Reports and Periodic Adverse Drug Experience Reports) to ANDAs, continue to send these to the following address:
