Split Area Code
This area code exists because its parent region ran low on available numbers: the parent territory was divided geographically, this code took over one part of it, and the parent kept serving the rest. Existing customers generally keep their numbers — only the code changes for the newly drawn region.
This area code was split from area code 901 (Memphis).
In service since: 12-Feb-2001
