Area Code Prefix Change



Background


Background

The California Public Utilities Commission has mandated a split in the 909 area code because the supply of new phone numbers in the 909 area code is so low. Another area code must be added to make more phone numbers available. Splitting the present 909 area in two, generally along the Riverside/San Bernardino county line and adding a new area code – 951. Because the split line follows the boundaries of telephone service areas rather than exactly following county boundaries, you should check the list to see which prefixes will be in the 951 area code.
