Dialing 302
Wilmington, DE is currently served by the single area code 302, with no overlay. Ten-digit dialing (area code + seven-digit number) always works and is increasingly the norm nationwide; some local calls may still connect with seven digits. If a future overlay is added, 10-digit dialing would become mandatory.
From outside the US, dial +1 302 followed by the seven-digit number.
History of the 302 area code
302 is one of the original area codes assigned in 1947, when AT&T and Bell Laboratories created the North American Numbering Plan and divided the country into the first 86 numbering plan areas. It has served the Wilmington area ever since.
Is 302 a scam or spam risk?
302 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 302 number on your screen is no guarantee the caller is in Wilmington, DE or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
