Home: Resources: DoD Glossary

Our industry is full of technical terminology. We’ve put together a glossary of terms to help you navigate and communicate what your company needs.


ACRN: Accounting Classification Reference Number

This accounting code appears as a two-position alpha or alphanumeric. There are two types: Funding ACRNs, assigned when funds are allocated, and Contract ACRNs, assigned to each accounting classification citation within the contract and appearing only on award contracts. The two types of ACRNs are not required to match, as they operate independently of one another.

ASN: Advance Shipment Notice

A document that provides detailed information about a pending delivery so the purchasing agency can be prepared to accept the delivery.


BSM: Business System Modernization

The goal of BSM is to bring Defense Logistics Agency (DLA) in line with business best practices by re-tooling logistics and providing stronger IT support across all levels. Its precursor is DPMS (Distribution Planning and Management System), which was created to improve combat logistics support.


CAR: Corrective Action Request

When a supplier has a product, process, or service that a federal agency customer finds to be non-conforming or non-compliant, the supplier will receive a formal notification asking them to remedy the issue. Learn more about the different levels of CARs in our blog post.

CLIN: Contract Line Item Number

CLINs are an element of defense contracts that provide details about what is being purchased, such as quantities of products and amount of service hours.

COC: Certificate of Conformance or Compliance

Although specifications are laid out in the contract, upon delivery, suppliers provide additional documentation verifying that the product was made in accordance with the agency’s specifications.

Class 1 Gen 2 Tags

Class-1 Generation-2 (Gen-2) radio frequency identification tags are used for item-level identification. Class 1 refers to the tag’s functionality: Class 1 tags can be HF (high frequency), which can read 20 tags at once, or UHF (ultra high frequency), which can read 200. Gen-2 refers to the standards of the tag type and the overarching system. Gen-2 offers faster, more flexible tag reading than previous generations. See Odyssey’s RFID label options here.


Data Matrix Code

A 2D label marking made up of black and white modules typically arranged in a square, often resembling a QR code. The Data Matrix is the required method of UID (Unique Identification) that defense suppliers must follow, in accordance with MIL-STD-130 (see below).
