nameplate

A nameplate is a plate or label attached to a device, piece of equipment, or surface that displays identifying information such as the product name, model, serial number, manufacturer, and technical specifications. Nameplates help identify, operate, maintain, and verify compliance for the item.

Nameplates are typically made of metal (brass, stainless steel, aluminum) or durable plastics and can be engraved, stamped, etched, printed, or embossed. They are affixed by screws, rivets, adhesives, or magnetic mounts and are designed to withstand wear, corrosion, and harsh environments. The data shown often includes electrical ratings (voltage, current, power), environmental or safety notices, certifications, and dates for service or revision.

Common applications include industrial machinery, electrical panels, consumer electronics, vehicles, and building doors or office plaques displaying a person’s name or role. In asset management, nameplates serve as identifiers for inventory tracking, maintenance planning, and regulatory documentation.

In some contexts, nameplate describes the official capacity or branding of an item, such as the nameplate capacity of a power plant or the visible signage of a company or product line. The term can also refer to a desk or door plaque bearing a person’s name and title.
