E56

E56 is a designation used in several distinct domains, and there is no single, universally defining meaning. The combination of a letter and numbers is a common way to label routes, products, courses, or datasets, and E56 is one example of such labeling.

In transportation, E56 denotes a route in the international European road network. The E-road network, overseen by the United Nations Economic Commission for Europe, assigns two- and three-digit numbers to cross-border highways. An E56 road is described in official routing documents as connecting multiple regions across participating countries, though its exact path and endpoints can be adjusted in updates to the network.

In manufacturing and technology, E56 is sometimes used as a model or part number by different vendors. In these contexts, the specifications, capabilities, and compatibility of an E56 item depend entirely on the manufacturer and the product family, so consulting the relevant datasheet or catalog is required.

In education and administration, E56 can appear as a course code, laboratory designation, or project identifier within institutions. Such usage varies by organization and does not imply a shared standard.

Because E56 is used in multiple, unrelated systems, the specific meaning is highly context-dependent. When encountering the label, it is best to consult the surrounding documentation or a field-specific index to determine what E56 refers to in that particular case.
