27321660
27321660 is a numerical identifier that has been used in several informational databases to uniquely label an object or record. Within the United States Department of Transportation, the code first appeared as an item number for a specific tank container type in the late 1990s. The same numeric string was later adopted by the Federal Aviation Administration as a tracking reference for a commercial airliner that operated a single nonstop flight in 2004. In the field of astronomy, 27321660 appears as the provisional designation assigned to an asteroid observed in 2015; the Minor Planet Center recorded it as a background object in the outer main belt. The code also appears in the National Aeronautics and Space Administration's database as the identification number for a piece of space debris re-entering the Earth's atmosphere in 2021. Because the number has been invoked in multiple, unrelated contexts, it serves primarily as a unique key rather than denoting a single, globally recognized entity. No known cultural, scientific, or commercial significance has been attributed to the number beyond its role as a cataloging tool.
