Which of the following is NOT a section for the AIC Codes?

The correct choice reflects an understanding of the structure and organization of AIC Codes within USPS operations. AIC Codes, or Accounting and Inventory Control Codes, are utilized to categorize transactions accurately for accounting purposes.

The AIC Codes typically encompass areas related to receipts, disbursements, and various product types, such as stamps. Receipts pertain to incoming funds, disbursements relate to outgoing funds, and stamps represent a product line that needs to be accounted for within the financial system.

In contrast, invoices are typically not categorized under AIC Codes, as they relate more to the documentation required for billing and not to the classification of financial transactions themselves. Invoices record the sale and serve as proof of the transaction but do not reflect the accounting categories defined by the AIC Codes. This distinction is crucial for maintaining accurate financial records and ensures that all accounting practices comply with established protocols. Therefore, invoices do not fit within the typical structure of AIC Codes, making this choice the correct answer.
