A Line of Accounting (LOA) is the funding associated with a defense organization’s budget. By understanding the elements that comprise a LOA, you can determine the Service designator, fiscal year, appropriation, subhead, object class, plant UIC, sub-allotment, authorized accounting activity, transaction type, and Work Breakdown Statement (WBS) element/cost element.


The Appropriations code is tied to the Appropriation Categories


Example LOA Navy ERP Number: AA1701506U5B1253001900501202D00000A00000039869

LOA Picture

Each of the various federal agencies has a different method for cost accounting. A typical string of accounting data found on a requirements document is 30 to 40 characters in length. Each of these characters is broken out differently in accordance with the accounting practices of the providing agency. However, the first 9 digits are the same for all agencies.
