Procurement Instrument Identifiers in Government Contracting

Assigned for each solicitation, contract, agreement, or order and related procurement instrument.

Elements of a PIID. The PIID consists of a combination of thirteen to seventeen alpha and/or numeric characters sequenced to convey certain information. Do not use special characters (such as hyphens, dashes, or spaces).

Positions 1 through 6. The first six positions identify the department/agency and office issuing the instrument. Use the AAC assigned to the issuing office for positions 1 through 6. Civilian agency points of contact for obtaining an AAC are on the AAC Contact list maintained by the General Services Administration.

Positions 7 through 8. The seventh and eighth positions are the last two digits of the fiscal year in which the procurement instrument is issued or awarded. This is the date the action is signed, not the effective date if the effective date is different.

Position 9. Indicates the type of instrument by an upper-case letter in position nine.

Positions 10 through 17. The number assigned by the issuing agency in these positions. Agencies may choose a minimum of four characters up to a maximum of eight characters to be used.

Amendments to solicitations. Number amendments to solicitations sequentially using a four-position numeric serial number added to the 13–17-character PIID beginning with 0001.

Modifications to contracts, orders, and agreements. Number modifications to contracts, orders, and agreements using a six-position alpha or numeric, or a combination thereof, added to the 13–17-character PIID.
