Morphology

social + security + number

The phrase literally combines 'Social Security' (an institutional/program name) + 'number', so a learner can infer it is a number associated with a social-security program. However, understanding that 'Social Security' refers to a specific government identification/program (and that 'security' here is an institutional, not literal, sense) requires world knowledge beyond the literal word meanings, so it is not fully transparent to all B1 learners.

Etymology

Social Security number: The name Social Security number comes from when the U.S. government gave each worker a unique number to record their Social Security payments and work history. Think of it as a personal code that lets officials find your files, so today it means your 'official ID number'.
