As of September 2014, the area code 976 had yet to be assigned to a city or state. It is a country-specific area code for the United States.
A list of area codes that have been developed but not assigned to specific places exists. These are created for future use in the event that a region becomes so densely populated that a new area code is required. A number of web pages can be used to look up the city and state to which an area code is assigned. AreaCode.org is one of these pages that is both accurate and current as of 2014.
