Delaware area codes
Delaware has a single active area code. The original 1947 code was 302.
The busiest codes by active prefixes are 302 (Wilmington).
Time zone is uniform across the state's codes: Eastern.
A statewide single code is getting rare in the NANP — most states have long since added overlays. 302 still covers everything from Wilmington to New Castle on one code.
302, in service since 1947, anchors Wilmington, carries 650 active prefixes across 30 rate centers, split among 32 carriers. 494 of its prefixes are pooled — shared between carriers in thousands-number blocks. It is the only area code serving Delaware. NANPA projects its capacity to last until 4Q 2034. Local dialing is ten digits.
Numbers in the toll-free 8YY family are absent here by design: they carry no state assignment and answer anywhere in the US, Canada and the Caribbean.
