Geographic Coverage & Key Cities

The 302 area code covers the entire state of Delaware, including all three counties:

  • New Castle County: Cities like Wilmington and Newark
  • Kent County: Home to Dover, the state capital
  • Sussex County: Includes coastal towns like Rehoboth Beach and Lewes

Delaware has used this single area code since 1947, making it one of the original 86 area codes in the U.S. This simplicity provides a clear regional identity—when customers see “302,” they immediately know it’s Delaware. It connects approximately 990,000 residents and is projected to remain the only code in use until at least 2033.

This geographic consistency supports businesses targeting any part of Delaware, from corporate hubs in Wilmington to tourist services in Rehoboth. With no overlays or confusing number splits, your brand stays straightforward and recognizable.
