ERC
An
ERC is an
easily recognizable code for the
North American Numbering Plan. This applies to all area codes that end in double digits, such as 800, 877, 900, 700, and others not yet assigned. The state of
Nevada requested that its new area code be "lucky" 777, but this was denied by
NANPA because it is an ERC, to be used only for special purposes like inward
WATS.
ERC is also a political party in Catalonia, in full Esquerra Republicana de Catalunya
ERC (European Rugby Cup) is the organisation that runs the Heineken Cup.
