310 Area Code History
310 area code was made in 1991 in order to meet the increased needs for new telephone numbers in the area that has been using 213 area code. This area code is still in use in the same places as before. It was the beginning of 1997 when 310 area code was split to form 562 area code, since the need for new telephone numbers has increased again. In the following 1998, a relief plan had to be considered. After just several months, the plan was approved. The plan was to create an overlay area code. This was the first overlay of the codes that ever happened in California. Ten-digit dialing was mandatory in both 424 and 310.
