However, this plan was never implemented and the area code is not projected to reach full capacity until the middle of 2021. As a result, 757 is one of the few urbanized area codes where seven-digit dialing is still possible, although not for much longer. In April 2019 it was announced that a plan for an overlay area code was proposed, with the current pool of numbers for the 757 code projected at the time to run out in late 2021. The timeline for implementing the overlay has not been announced yet. On February 5, 2020 it was announced that the overlay area code will be 948. This will make ten-digit dialing mandatory in 757/948. Now, the current pool of numbers for the 757 code is not projected to run out until the second quarter of 2023, delaying implementation of area code 948.
