Plain-language definition
Plain-language definition
A manufacturer-assigned identifier for one individual device or part.
Why it matters
Serials can be sensitive operational identifiers, so public displays should mask them when full disclosure is unnecessary.
Technical detail
A serial number identifies a specific unit within a product family and may support warranty, service, provenance, or loss-status checks.
Examples
- A repair intake records the device serial while the public listing shows only a masked value.
