Area code 228
Area code 228 covers Biloxi, Mississippi. We hold 2,071 allocated blocks for it across 12 rate centres, split 46% mobile, 40% landline and 14% VoIP.
How far area code 228 reaches
Area code 228 covers 12 rate centres, so two 228 numbers are not always a local call to each other.
A rate centre is a billing boundary rather than a postal one, which is why an area code can span several and a single city can contain many. It is also why the code alone cannot place a subscriber beyond a rough region.
Mississippi is split across 4 area codes — 662, 601, 769, 228. By allocated blocks 228 is the 4th largest of them, holding 14% of the Mississippi total.
Where 228 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Ocean Spg and Xxxxxxxxxx are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.
