 Western Riverside County was split off from 909 into area code 951 on July 17, 2004.
 Originally on that same date, the area retaining the 909 area code was to be overlaid by a new area code 752.
 However, this overlay plan was shelved prior to the 909/951 split, and area code 752 was returned to the NANPA numbering pool to be assigned at a later date.
