Requesting a Pre-Assigned Application number:
- Before you request a pre-assigned eCTD application number, apply for a secure email with the FDA by contacting Wendy Lee. If using a US Agent to request the number, please be sure that the agent has established secure e-mail.
Send one email per application number request to email@example.com. Please note that at this time the Electronic Submission Gateway (ESG) cannot accept requests for pre-assigned numbers.
