History of Area Code 854

Area code 854 began service on October 19, 2015. The North American Numbering Plan Administrator added it as an overlay to area code 843. That change meant new phone numbers in the same region could receive either 843 or 854.

Area code 843 had served the region since 1998, when it was split from area code 803. The 854 overlay was created because the 843 region needed more phone numbers. After the overlay began, 10-digit dialing became required for local calls in the 843 and 854 service area.
