## Abstract

DoD, GSA, and NASA are issuing a final rule amending the Federal Acquisition Regulation (FAR) to implement a uniform Procurement Instrument Identification (PIID) numbering system, which will require the use of Activity Address Codes (AACs) as the unique identifier for contracting offices and other offices, in order to standardize procurement transactions across the Federal Government.
