AB123

AB123 is an alphanumeric identifier used across multiple domains to label items, events, or records. It has no fixed meaning on its own, and the interpretation depends on the context or issuing organization.

In transportation, AB123 can appear as a service number for a flight, train, or bus. Airlines and rail operators assign such codes to identify specific routes, schedules, or entities within their systems.

In manufacturing and retail, AB123 frequently serves as a part number, model code, or catalog identifier. It links to product specifications, compatibility data, and version history in catalogs and inventories.

In government or policy contexts, AB123 may denote a bill number or regulation code, with its exact status depending on jurisdiction, legislative session, and associated documentation.

In science and commerce, AB123 can be a catalog number for a chemical, a reagent, or a dealer's product code, or an internal reference in research datasets. Interpretation requires source metadata.

Because AB123 is not unique to a single reference, reliable identification depends on context, accompanying identifiers, and source documentation.
