Do All Manufactured Products Contain a Serial Number?

Not all manufactured products contain a serial number. Serial numbers are used for inventory and identification purposes, according to Computer Hope. Products with a high risk of counterfeiting often feature serial numbers.

Manufacturers use serial numbers to make it easier to find replacement parts for a specific product, states Computer Hope. These numbers are also valuable tools used in quality control and a way to identify stolen or counterfeit products. Some examples of manufactured products that have serial numbers include computers, mobile phones, televisions and other electronic devices. Software products also have serial numbers to make it difficult for individuals to distribute unauthorized copies.
