Applications of Serial Numbering

For more details on this topic, see Numbering scheme.

Serial numbers identify otherwise identical individual units with many, obvious uses. Serial numbers are a deterrent against theft and counterfeit products, as they can be recorded, and stolen or otherwise irregular goods can be identified. Banknotes and other transferable documents of value bear serial numbers to assist in preventing counterfeiting and tracing stolen ones.

They are valuable in quality control, as once a defect is found in the production of a particular batch of product, the serial number will identify which units are affected.
