What does the acronym OIG stand for in postal service context?

In the postal service context, OIG stands for Office of Inspector General. This office is an independent agency within the United States Postal Service that aims to provide oversight and ensure integrity in postal operations. The OIG conducts audits, investigations, and assessments to prevent fraud, waste, and abuse within the postal system. It plays a vital role in maintaining transparency and accountability, helping to safeguard postal resources and improve efficiency.

The other options refer to terms that do not accurately represent the responsibilities or the structure associated with postal oversight. The Office of Internal Governance, Office of Integration and Guidance, and Office of Information Gathering do not exist in the same context and are not recognized within the framework of the U.S. Postal Service's operations. Thus, the Office of Inspector General is the correct and most relevant designation.
