History of the 346 Area Code
Houston used only area code 713 for decades. On November 2, 1996 the suburbs were split off as 281. On January 16, 1999 the boundary was removed and 832 was added to the whole region.
Those three codes kept filling up, so 346 entered service on July 1, 2014 as a fourth overlay. A fifth code, 621, followed on January 23, 2025.

Is a Call From 346 a Scam?
Most 346 calls are from ordinary Houston homes, mobile phones and businesses. Because 346 is newer and less familiar, some people assume it is fake. It is a real Houston code, but like any code it can be spoofed.
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 346 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).
