909 and the Inland Empire
The Inland Empire is one of the fastest-growing parts of California and a major hub for warehouses and trucking, thanks to its rail lines, freeways and an international airport in Ontario. Logistics, delivery and staffing companies there make and receive a huge number of calls, which is one reason 909 needed an overlay.
How to Dial a 909 Number
You need the area code for every call, even a local one.
- From the US or Canada: 1 + 909 + the seven-digit number
- From another country: your exit code + 1 + 909 + the seven-digit number
Is a Call From 909 a Scam?
Most 909 calls are local residents, employers and delivery services. Job-related scams are worth watching for here, especially texts that offer warehouse or delivery work and then ask for personal details or a payment.
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 909 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).
