Noun
en-noun|sg=PIN number

Usage notes
"PIN number" is a pleonasm as the "N" of "PIN" stands for "number".
The use of "PIN number" rather than "PIN" is widespread but is avoided by careful speakers and writers.
Some people may argue that "PIN number" is not redundant, as it avoids confusion with the word pin.
