Delaware was assigned a single area code in 1947: 302, covering the entire state. For 78 years 302 has carried all of Delaware — Wilmington in the north, Dover in the middle, Rehoboth and the beaches in the south — the First State served by its first and only area code.
Delaware is one of only 11 US states that have never received an additional area code. Its small geography (49th of 50 by area), small population (45th of 50), and stable cellular density mean 302 has covered the state without splits or overlays for nearly eight decades.
Despite being one of the smallest states, Delaware is one of the most economically important — half of all publicly-traded US companies and 60%+ of Fortune 500 firms are incorporated in Delaware. Every corporate registered agent uses 302, making it one of the most-dialed corporate-services area codes in the country.
Delaware's 302 area code appears on more US corporate documents than any other prefix. Over 60% of Fortune 500 companies and roughly half of all US publicly-traded firms are incorporated in Delaware (despite being the 2nd-smallest state) because of the state's favorable corporate law and Court of Chancery. Every registered agent of those companies uses a 302 phone number.
