History of the 661 Area Code
- 1947: Southern California is in 213.
- 1957: 805 is created when 213 is reduced in size. It includes the coast and the inland valleys.
- February 13, 1999: the eastern, inland part of 805 is split off as 661.
Since the split, 805 has been a coastal code and 661 an inland one. The coastal side is covered in our 805 area code guide.
Three Regions, One Code
The places inside 661 are quite different from each other. Bakersfield is a center for oil and farming at the southern end of the Central Valley. Santa Clarita is a suburban city just north of Los Angeles, known for film production and a large theme park. Lancaster and Palmdale sit in the high desert of the Antelope Valley, where the aerospace industry is a major employer. A 661 number could come from any of the three.
How to Dial a 661 Number
You need the area code for every call, even a local one.
- From the US or Canada: 1 + 661 + the seven-digit number
- From another country: your exit code + 1 + 661 + the seven-digit number
Is a Call From 661 a Scam?
A 661 call is usually a local household or business. Job offers by text, solar panel sales calls and fake utility shut-off warnings are the kinds of unwanted calls to be careful with.
Watch for these warning signs:
- Threats of arrest, a lawsuit or a service shut-off unless you pay today
- Offers of a prize, a loan or a job that need a fee first
- Callers who already know part of your details and ask you to “confirm” the rest
- One-ring calls that try to make you call back
Caller ID can be spoofed, so the number on your screen does not prove where a call comes from.
What to do with an unknown 661 call
- Do not answer numbers you do not know.
- Never share a PIN, password or passcode with someone who called you.
- Block repeat callers and turn on your carrier spam filter.
- Report scam calls at reportfraud.ftc.gov and register at donotcall.gov.
- Forward spam texts to 7726 (SPAM).
