Consolidation will result in a new postal zip code.

Fact:  No factual source is cited to support this statement.  It is a variation on the "We'll lose our post office" rumor (see rumors 6 and 38), and is entirely fabricated. The most applicable case-study in this regard is again, Iron River.  Before consolidation there, Iron River and Stambaugh each had a separate zip code.  Thirteen years later, they still do today.
