Abstract:
A method and apparatus for detecting a stale number. A stale number detection device obtains a call number, a call number contact creation date, and a call number issue date for the call number. The stale number detection device determines that a stale number state exists when the call number issue date is later than the call number contact creation date. The stale number detection device generates a stale number notification based on the stale number state.
