Before the implementation of
number pooling, area code 757 was projected to run out of numbers as early as 2002. A plan was developed that would have created a concentrated overlay in the Hampton Roads metro area leaving all of the Eastern Shore in 757. This would have made
ten-digit dialing mandatory in southeastern Virginia. However, this plan was never implemented. In 2019, area code 757 was projected to exhaust its numbering resources by late 2021, triggering planning for mitigation of central office code exhaustion, and the announcements of planning for an
overlay complex, and the selection of area code 948 in 2020. An overlay was chosen over the option of splitting 757. A split could have meant Virginia Beach, Chesapeake, and Norfolk, for example, retaining 757 and the rest of the area changing to 948, or vice versa. The NANPA decided, and the State Corporation Commission agreed, that simply requiring everyone to dial ten digits instead of seven would have caused far fewer problems than the inconveniences that would be caused by an area code split. ==In popular culture==
