In Washoe County they say “Nevada Concealed Weapons Permit” but our Sheriff’s Office calls them “CCW” on their website and in their offices.

While the statue explicitly states permits are "Concealed Firearm Permit", the common and widespread usage of CWP and CCW has made all three interchangeable. Well, that's my 2 cents.
