The Letter of Authorization must be submitted on company letterhead and signed with a traditional handwritten signature. Clients who have WebTrader ESG user accounts must upload an electronic copy of their Letter of Authorization via the FDA ESG User Portal (https://esgportal.fda.gov/). All other clients must send an electronic copy of their Letter of Authorization to the ESG Help Desk at ESGHelpDesk@fda.hhs.gov. Clients are no longer required to submit a physical copy to the FDA.
