Morphology
The meaning 'personal identification number' is directly and transparently derivable from 'PIN' (itself denoting a numeric access code) plus 'number'; the phrase is merely redundant (a pleonasm) rather than idiomatic. This compositional structure is straightforward and common in everyday use, so a B1 learner who knows both constituents will understand it immediately.
Etymology
PIN number comes from the letters PIN, which stand for 'Personal Identification Number', a short secret code you type to open bank accounts or phones. Saying PIN number repeats the word 'number', but it still means the short secret code used to access secure accounts.
