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 909 (San Bernardino).

In service since: 17-Jul-2004
