South Carolina gets 854 overlay area code for coastal area

North American numbering plan administrator Neustar, Inc. (NYSE: NSR) said that an additional area code (854) has been assigned to the existing 843 area code that serves the coastal area of South Carolina, including the cities of Charleston, Hilton Head Island, Myrtle Beach, and Florence.

The new dialing pattern for the area will require 10-digit dialing for all local calls into, out of, and between the existing 843 area code and the new 854 area code. Toll calls will continue to require 1+10-digit dialing. Existing 843 telephone numbers will not change.

Neustar has forecasted that numbering resources in the 843 area code will be exhausted by the end of 2015. The South Carolina Public Service Commission has directed all local exchange service providers to activate the new area code to ensure the availability of numbering resources in a manner that is most efficient and least confusing for consumers, while minimizing possible disruption to consumers and businesses.
