Full Form of OUO
What is OUO?
OUO stands for Official Use Only, a security marking used on government and public sector documents in India to indicate that the content is intended solely for official purposes and should not be shared with the public or unauthorized personnel. It is a restricted access classification, lower than confidential but higher than unclassified, and is commonly applied to internal memos, policy drafts, reports, and correspondence that contain sensitive but not secret information. In Indian bureaucracy, OUO markings guide document handling, ensuring that files are not circulated beyond the designated officers or departments. This practice is prevalent across central and state government offices, public sector undertakings, and regulatory bodies. For competitive exams like UPSC Civil Services or Staff Selection Commission, understanding document classifications including OUO is relevant for questions on office procedures and government administration. The marking helps maintain administrative efficiency and protects operational details from premature disclosure, balancing transparency with the need for secure governance.
