What Is the 661 Area Code?

History of the 661 Area Code

The Split from 805

Before 1999, the location of 661 area code didn’t exist as a separate entity. The entire region used the 805 area code, which originally covered a massive portion of Southern and Central California.

On February 13, 1999, the 661 area code officially came into service. This split occurred due to:

• Rapid population growth in the Bakersfield and Antelope Valley regions
• Increased demand for telephone numbers from businesses
• The proliferation of cell phones, fax machines, and pagers
• Projected exhaustion of available 805 numbers

The split divided the 805 area code territory, with 661 taking the inland and northern portions while 805 retained the coastal areas including San Luis Obispo, Santa Barbara, and Ventura.

Overlay Considerations

Unlike some California area codes that have received overlay codes (where multiple area codes serve the same geographic area), the 661 region hasn’t yet required this solution. However, telecommunications experts predict that continued population growth may eventually necessitate an overlay code.

When overlays occur, residents must dial ten digits (area code plus number) even for local calls. As of now, the location of 661 area code remains the sole area code for its territory.
