What Changed With 324?

How to Dial a 904 Number
Because more than one area code can serve the same streets, always dial the full ten-digit number.
- From the US or Canada: 1 + 904 + the seven-digit number
- From another country: your exit code + 1 + 904 + the seven-digit number
Is a Call From 904 a Scam?
A 904 call normally comes from a resident or business in the Jacksonville area. The city has a large port, several military bases and many banking and insurance offices, so service calls from 904 are common.
Watch for these warning signs:
- A recorded voice that says an account is locked or suspended
- A caller who wants payment by gift card, wire transfer or crypto
- A text with a link about a delivery, a toll or a refund
- A request for a one-time code that was just sent to your phone
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 904 call
- Let unknown numbers go to voicemail. A real caller leaves a message.
- Look up the company and call the number on its website.
- Block the number on your phone.
- Report scam calls at reportfraud.ftc.gov and register at donotcall.gov.
- Forward spam texts to 7726 (SPAM).
