2-27.5 Presolicitation Notices If the purchase⁄SCM team wishes to identify suppliers, it may do so by issuing a presolicitation notice (also called a “sources sought” notice) before issuing the RFP. The notice should: Describe the upcoming Postal Service requirement and any applicable qualification requirements. Announce any planned presolicitation conferences. Specify a date by which the supplier must respond to the notice to ensure inclusion on the RFP mailing list.
