NPA 757 split from 804

Area code 757 was established on July 1, 1996, as a geographic split from 804. The new code served the Hampton Roads metropolitan area and the Eastern Shore, while 804 continued to serve central Virginia. The split was implemented to address number exhaustion in the rapidly growing southeastern region of Virginia.
