N American Numbering Plan

There is an organization that keeps track of all the telephone exchanges and numbering for N America. It is called the N American Numbering Plan.

There has to be interconnected planning on numbering for all countries in all continents to avoid overlapping area codes.

To help keep them separate, each country has an entry code and then area codes afterwards. If two countries had the same entry code it would cause a meltdown in the communications system.

So far we have avoided that!
