serienummers

Serial numbers are unique identifiers assigned to individual items to distinguish one unit from another within the same product line. They enable traceability across the life cycle of a product, from manufacture through distribution, sale, and service. A serial number may encode information such as the manufacturer, production facility, date, and a unique sequence, or it may be a random string.

In practice, serial numbers come in many formats. Some are purely numeric, others alphanumeric, with lengths that vary by industry. Some use check digits or embedded codes to detect errors or convey production data. Many products carry serial numbers on labels, engraving, or embedded in electronic circuitry; accompanying barcodes, QR codes, or RFID tags allow automated data capture.

Serial numbers are assigned at or near production and are recorded in enterprise systems such as manufacturing execution, ERP, or CRM platforms. The linkage between a serial number and the product’s metadata—model, batch, purchase history, service records—facilitates warranties, recalls, asset management, and aftermarket support. They also enable recalls by identifying potentially affected units quickly.

They are distinct from lot or batch numbers, which identify groups of items produced under similar conditions. They may be used together with other identifiers such as model numbers or VINs. Standards and practices for serial numbers vary by industry, with common aims including uniqueness, traceability, and interoperability through barcodes and other data carriers.

Privacy and security considerations arise because serial numbers can enable tracking of individual items and their ownership. Careful handling and access controls help prevent misuse.
