I don’t see where they are referred to as being National Panhellenic Conference (NPC). I only saw Panhellenic Council, which is a big difference. A member group of the NPC does have to meet the minimum requirements for membership. One of the criteria is that it is national in scope; 13 chapters with the youngest chapter being established no less then two years. A Collegiate Panhellenic Council can have member groups of almost any type of sorority. They can be NPC, NPHC, MCGLO, professional, local, or regional. As long as they are following their CPH constitution and by-laws, regarding membership, then it isn’t a problem.

Regarding similar names, it is more common then you may think. There are, for example, three national organizations named Delta Phi Epsilon. One is an NPC member. The other two are a related professional Foreign Service fraternity and sorority. There are many interesting threads about this subject.
