Delaware's area codes have undergone significant changes over the years. Originally, the state was served by a single area code, 302, which was established in 1947. As telecommunications needs grew, an overlay area code, 302, was introduced in 1996 to ensure a sufficient supply of phone numbers without affecting existing ones. This overlay allowed Delaware to accommodate the proliferation of mobile phones and other devices while maintaining the familiarity of the original area code. These changes in Delaware's area codes reflect the evolving telecommunications landscape in the state, ensuring seamless communication for its residents and businesses.
