490000002

490000002 is a nine-digit numeric identifier used in various information systems to uniquely designate an item, record, or event. As a neutral numerical string, it carries no inherent meaning outside the context in which it is assigned.

In commercial and inventory environments, codes of this type function as internal product identifiers or stock-keeping units (SKUs). They enable tracking across procurement, warehousing, and sales processes even when product descriptions change. In data management and information systems, such numbers often serve as surrogate keys or transaction identifiers within databases and log files, allowing records to be linked without exposing sensitive details.

In bibliographic and archival settings, similar numeric identifiers may appear as part of catalog entry numbers or asset tags, but 490000002 itself does not correspond to an established international standard by itself. In software development and testing, the string may be used as a placeholder or test value to simulate IDs.

Because there is no fixed universal meaning, determining what 490000002 refers to requires examining the surrounding metadata: the database schema, the application, or the documentation where the identifier is used. If encountered in practice, consult the system's data dictionary or contact the data steward for the authoritative interpretation.
