System Overview
The Management Account Structure Codes System (MASC) is an online system of the United States Department of Agriculture (USDA). It provides users with direct system access to add, replace, delete, and query table data. MASC is composed of tables and accounting documents that contain support information for edits, references, reports, and identifiers used in application programs. This support information (e.g., descriptions, accounting codes, activity codes, Treasury symbols) ensures that the National Finance Center (NFC) maintains a high degree of data integrity and validity. Therefore, it is important that MASC contains up-to-date and accurate data.
