seriennummer

Seriennummer (serial number) is a unique identifier assigned to a single item to distinguish it from all other units. It is used for identification, traceability, warranty management, service history, and recalls. Unlike model numbers or part numbers, which describe a product type, the serial number identifies a specific unit and its history.

Serial numbers appear in many formats, typically alphanumeric or numeric, and may include codes for manufacturer, production line, date, and a check digit. They can be printed, etched, stamped, or embedded in components, with optional encoding on barcodes or QR codes for easy scanning. In complex supply chains, the serial number is linked to data in enterprise systems such as ERP, CRM, or inventory management software.

Assignment and use. Serial numbers are usually generated during manufacturing or by authorized distributors and then registered in a database. Scanning or entering the number allows users to retrieve information about the unit, including production details, ownership, maintenance records, warranty status, and whether it has been recalled. Serial numbers also enable anti-counterfeiting measures when combined with tamper-evident labeling or secure databases.

Relation to other identifiers. A serial number identifies a single unit, while a model or product number defines a type. Batch or lot numbers indicate a production run, and Vehicle Identification Numbers (VINs) perform a similar function for vehicles at a higher level of aggregation.

Overall, Seriennummer serves as the fundamental unit-level identifier that supports traceability, ownership, and after-sales service across varied industries.
