For Suppliers


State of Delaware eSupplier Portal


The State of Delaware eSupplier Portal is a secure login site for new suppliers to register and existing suppliers to manage their information. The State does not accept IRS Form W-9, instead all suppliers are required to register through the eSupplier Portal.

Successful submission and approval of a new supplier registration enables the creation of a State of Delaware supplier record. The Taxpayer ID (SSN or EIN) and supplier name are submitted to the Internal Revenue Service for “matching.” If the Taxpayer ID and name do not match, the supplier record cannot be approved.

Existing suppliers who have not previously registered through the eSupplier Portal will need to obtain a user ID and password in order to submit changes to their State of Delaware supplier record.

Detailed instructions for submitting new registrations, obtaining user IDs and passwords, and submitting change requests are located on the FAQs / Contact Us page of the eSupplier Portal.

Please Note: The eSupplier Portal does not contain invoices, payment history, or payment details for payments made to suppliers.

If you have questions about completing this form or specific comments about a form that you have submitted, please contact the supplier maintenance team by phone at 302-672-5000 or by email at FSF_Supplier_Maintenance@delaware.gov.
