The California Public Utilities Commission is reminding everyone that starting at the end of the month, phone numbers with an 837 area code will begin to share the current 530 area. The overlay means both area codes will intermingle within the same geographical region. the transition will be made easier by the fact that it’s already necessary to enter an area code, even for local calls. The change is necessary because all of the seven number combinations following 530 are becoming used up.
