The Dialing Doughnut

California’s first doughnut-shaped area code split goes into effect today, with a new code--323--replacing all the current 213 numbers except in a three-mile-diameter region in downtown Los Angeles. Until Jan. 16, 1999, both area codes will still work in the area covered by the new change. After that, those dialing 323 locations will need to use the new area code.
