Editing Serial number (section)

[[File:TMP246M-M-352F serial number 20170608.jpg|thumb|Serial number of a [[laptop]] computer]] In [[smartphone]]s, serial numbers are extended to the integrated [[Electronic component|components]] in addition to the electronic device as a whole, also known as serialization. This gives unique individual parts such as the screen, battery, [[Integrated chip|chip]] and camera a separate serial number. This is queried by the software for proper release for use.{{clarify|date=September 2023}} This practice by manufacturers limits the ''serial '''number''''' electronic devices.

===Serial numbers for intangible goods===
Serial numbers may be used to identify individual physical or intangible objects; for example, [[computer software]] or the right to play an online multiplayer game. The purpose and application is different. A software serial number, otherwise called a [[product key]], is usually not embedded in the software but is assigned to a specific user with a [[software license | right to use]] the software. The software will function only if a potential user enters a valid product code. The vast majority of possible codes are rejected by the software. If an unauthorized user is found to be using the software, the legitimate user can be identified from the code. It is usually not impossible, however, for an unauthorized user to create a valid but unallocated code either by trying many possible codes, or [[reverse engineering]] the software; use of unallocated codes can be monitored if the software makes an [[Internet]] connection.
