History of the 321 Area Code
- 1947: all of Florida is in 305.
- 1988: Central Florida and the east coast become 407.
- 2000: Brevard County is split from 407 and becomes 321. At the same time, 321 is also overlaid on the Orlando area.
- Early 2000s: new 321 numbers stop being issued in the Orlando counties, so the code becomes mainly a Space Coast code.
- October 2021: ten-digit dialing becomes required in the part of 321 that is not shared with 407.
Three, Two, One, Liftoff
The code exists because a local resident asked for it. A space museum volunteer petitioned for 321 to be assigned to the Cape Canaveral area as a tribute to the countdowns that have launched so many spacecraft from there. Regulators agreed. It remains one of the few area codes in the country picked for its meaning, not just for being available. The Orlando side is covered in our 407 area code guide.
How to Dial a 321 Number
You need the area code for every call, even a local one.
- From the US or Canada: 1 + 321 + the seven-digit number
- From another country: your exit code + 1 + 321 + the seven-digit number
Is a Call From 321 a Scam?
A 321 number usually belongs to someone in Brevard County. Aerospace contractors, cruise lines sailing from the local port and beach rental agencies all call from 321. Free cruise and vacation calls imitate them.
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 321 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).
