## Abstract

DoD, GSA, and NASA are issuing a final rule amending the Federal Acquisition Regulation (FAR) to standardize use of unique Procurement Instrument Identifiers (PIID) throughout the Government. The lack of consistent agency policies and procedures for PIIDs subjected users of contract data, including the Federal Government, contractors, and the public, to potential duplicate, overlapping, or conflicting information from the different Federal agencies.
