Air Force Unique Management Coding for 

Materiel Management Aggregation Code (MMAC) 

1. ORIGINATOR: 

a. Service/Agency: U.S. Air Force, HQ AFMC/LGIA, Wright-Patterson AFB OH 

45433-5006

b. Originator: Mrs. Bobbie Ziolek

2. FUNCTIONAL AREA: Supply

3. REQUESTED CHANGE:

a. Title: Air Force Unique Management Coding for Materiel Management Aggregation 

Code (MMAC) 

b. Description of Change: The Air Force will require the use of a unique code to 

support legacy system requirements to adequately process supply transactions using EC/EDI 

processes. The unique code, Materiel Management Aggregation Code (MMAC), is a twoposition alpha code used in conjunction with/at the end of the national stock number (NSN) 

(rp 21-22 of DLSS transactions), to identify specific items (NSNs) to be managed by a 

specific manager. Separate MMACs apply to systems, programs, aggregations, selected 

federal stock classifications (FSCs), and technology groups. A separate 1270 qualifier is 

being requested so that the AF will continue to maintain control over this unique code list. 

Other Services/Agencies using DLMS should take no action concerning this code, merely 

perpetuate it for AF continued use. Per SPRC 02-2 recommendation, DLMSO has included 

in this proposal a comparable description of the MMAC for publication in MILSTRIP.

c. Procedures: 

(1) DoD. Revise MILSTRIP Appendix AP2.5, Stock or Part Numbers to insert new 

subparagraphs:

“AP2.5.2. When codes are required in addition to the NSN to properly identify the 

item being requisitioned and these codes are recognizable to the initial processing source, the 

codes will be entered in rp 21 and 22. If one digit only, entry will be in rp 21. Codes will be 

perpetuated with the material identification in rp 8-20. See examples below:

AP2.5.2.1. The USAF may use rp 21-22 to identify the Materiel 

Management Aggregation Code (MMAC Code) indicating a specific manager in 

accordance with USAF guidance. Separate MMACs apply to systems, programs, 

aggregations, selected federal stock classification (FSCs), and technology groups. 
AP2.5.2.1 The USN may use rp 21-22 to identify the Special Material 

Identification Code (SMIC) indicating a weapon system in accordance with USN 

guidance This code identifies the end item for which a requirement has been 

submitted.”

(2) Air Force. Air Force procedures are provided in the Air Force Manual (AFMAN) 

23-110, Volume 1, Part 4, Chapter 1, and Volume 2, Part 2, Chapter 3. 

4. REASON FOR CHANGE: This code is a primary data element for Air Force 

requisition processing that will continue to be used until a standard DoD weapon system 

coding methodology has been established to which the Air Force will have successfully 

reprogrammed.

5. ADVANTAGES AND DISADVANTAGES:

a. Advantages: The advantages are to Air Force legacy system requirements based upon 

the current operating software program logic. This requested change provides a logical 

interim step towards a planned transition to a standard weapon system coding structure 

and will ensure an uninterrupted flow of the requisition processing capability with Air 

Force legacy systems.

b. Disadvantages: None known.

b. Segment(s): LQ, Industry Code

c. Data Elements: Versions 4010 and 4030 (as identified in paragraph 6.A., above), DE 

1270 Code List Qualifier Codes. Add the code and code value implementation note to 

each of the ICs/DSs referenced under paragraph 6A, above. This will be a temporary 

assignment until such time as a unique qualifier code has been assigned by ANSI for the 

MMAC.

GQ Group Qualifier Code

Federal Note: Use to identify the Materiel Management Aggregation Code (MMAC). 

DLMS Note: Use to identify the MMAC for NSNs to be managed by a specific manager 

(i.e., system, program, aggregation, selected FSC, technology group). This is an Air 

Force-unique data element, meaningful to the Air Force only. Non-Air Force 

Components perpetuate without action. An ANSI data maintenance request has been 

prepared to request a new data element 1270 code qualifier assignment for the MAAC. 

The code source is identified as the Air Force Manual (AFMAN) 23-110, Volume 1.
