“The 314”
St. Louis residents are proud of their code. March 14, written 3/14, is celebrated locally as “314 Day”, with events and deals around the city. Because 314 now covers only the city and the closest suburbs, the number has become a badge of being from St. Louis itself, as opposed to the wider region.

Is a Call From 314 a Scam?
A 314 number usually belongs to someone in St. Louis or the inner county. Hospitals, universities and large employers in the city all use it, and scammers borrow the code to look local.
Watch for these warning signs:
- Fake bank or card fraud alerts that ask for your PIN or passcode
- Calls about Medicare, health insurance or a car warranty you never asked about
- Messages that claim a family member is in trouble and needs money
- Pressure to stay on the line and act right now
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 314 call
- Hang up as soon as a call feels wrong. You do not owe a stranger an explanation.
- Verify the caller through an official number, not the one they give you.
- Block the number.
- Report scam calls at reportfraud.ftc.gov and register at donotcall.gov.
- Forward spam texts to 7726 (SPAM).
