FAQ

Where is a 302 number from?

302 is assigned to Wilmington and surrounding areas of Delaware in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 302 a toll-free number?

No. 302 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.

Will 302 run out of numbers?

NANPA's current forecast projects exhaust in 4Q 2034 — decades of capacity remain.

Why am I getting spam calls from 302 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 302 number does not prove the call originated there — see our guide to spotting spoofed calls.
