Area Code 323 History - California

Significant events for area code 323

1998 Area code 213 was split, with area code 323 becoming a "doughnut" around 213 (central Los Angeles).
2017 The 1998 split will be reversed in August, effectively making 213 and 323 overlays to each other. The reason: 323 has run out of numbers while 213 has an excess of numbers.
