modelnummer

Modelnummer, or model number, is a stable identifier assigned by a manufacturer to designate a specific product design or version. It distinguishes a product family from other designs and is used in catalogs, parts lists, warranties, and technical specifications. It is not unique to individual units, unlike a serial number, which identifies a single item.

Model numbers are typically alphanumeric and may include hyphens or slashes. They can reflect the product line, revision level, or regional variant, but the exact scheme varies by company. The model number is usually printed on the product nameplate, packaging, manuals, or the device’s software or firmware update interface.

A model number differs from other identifiers such as a serial number and a stock-keeping unit (SKU). A serial number identifies a specific unit in the field, while a SKU is an internal retailer or distributor code. In some cases, a product sold in different regions shares the same model number with regional suffixes or variant codes to distinguish differences in specifications or labeling.

Uses and implications: Consumers rely on model numbers to verify compatibility with spare parts, accessories, and service limits. Manufacturers use them to manage warranties, recalls, and support documentation. When seeking assistance or ordering parts, providing the model number helps ensure accurate identification.

Localization: The term is used in multiple languages and may appear as modellnummer, modelnummer, or similar forms depending on locale. The concept spans industries such as electronics, appliances, automotive, and machinery. See also: serial number, SKU, part number.
