123UL

123UL is a designation encountered in various, unrelated contexts, typically as a catalog code, model number, or internal identifier. There is no single, universally accepted meaning for the term, and its interpretation depends on the organization or industry that uses it. The presence of the letters “UL” in a code does not, on its own, guarantee any specific standard or certification.

In manufacturing and consumer electronics, 123UL frequently appears as a product or component code within catalogs and manuals. It may label devices, accessories, or hardware revisions. The suffix “UL” in such codes sometimes leads to assumptions of safety listing, but a 123UL code does not inherently indicate Underwriters Laboratories certification; any certification would require separate verification.

In software, data management, and documentation, 123UL can serve as a tag, release identifier, or dataset label. As with other internal identifiers, its primary purpose is to distinguish items within a system or workflow rather than to convey external specifications to end users.

Variants of the code, such as 123UL-A or 123UL-B, are commonly used to indicate revisions, regional versions, or feature differences. These variants are typically defined by the issuing organization and described in product sheets, firmware notes, or change logs.
