Morphology

license + number

The meaning 'a unique alphanumeric code that authorizes a product' is directly derivable from combining 'license' (an authorization) with 'number' (an identifying numeric code); the phrase denotes the numeric identifier associated with a license. This is a straightforward, compositional noun-noun compound found across languages and common in software contexts, so a B1 learner who knows both words will readily infer the meaning.

Etymology

The noun license number comes from the numbers and letters shown on a car's metal plate. People or police write that number down to find the owner or report a car, so it is used to 'identify' a vehicle.
