The 228 area code covers Biloxi, Mississippi, Central time zone, and dates back to September 15, 1997. Note that porting and VoIP mean a 228 number can be used from anywhere — the code marks where the number was assigned.

271 central-office prefixes are currently active in this code, spread across 42 code-holding carriers. Thousands-block pooling applies to 195 prefixes, so a single prefix can belong to several carriers. Its prefixes map to 11 distinct rate centers.

NANPA projects numbering capacity to exhaust in 3Q 2105.

Dialing: 7D locally, 10D to other codes.

To check where a specific 228 number was issued, look up its six-digit prefix; to check who is actually calling, ignore the display and verify through an official callback number — caller ID is assertable and routinely spoofed.

228 was created from 601 in 1997.

FAQ

Is 228 a toll-free number?

No. 228 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 228 run out of numbers?

NANPA's current forecast projects exhaust in 3Q 2105 — decades of capacity remain.

Why am I getting spam calls from 228 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 228 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 228 number from?

228 is assigned to Biloxi and surrounding areas of Mississippi in the Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
