(February 2011) (Learn how and when to remove this template message) </Td> </Tr> <P> North American telephone area codes 715 and 534 are state of Wisconsin area codes covering most of the northern part of the state . </P> <P> The main area code, 715, was created along with Area code 414 as one of the two original area codes assigned to Wisconsin in October 1947 . Due to northern Wisconsin's low population density, for a long time 715 was one of the few original area codes to have never been split or overlaid . By 2010, however, 715 was almost out of numbers due to the proliferation of cell phones and pagers, so 534 was created as an overlay in the summer of 2010 . </P>
