The number still matters.

OpenCarrier.Network keeps the familiar North American–style NPA-NXX-XXXX number format. Each exchange owns an NPA (area code) and allocates numbers within it.

Modern underneath.

OCN rebuilds the telephone infrastructure with Internet technology while keeping the usability of the traditional network.

✆
