That 346 Area Code Spam Call Is Probably a Houston Spoof—Here is Why

That 346 Area Code Spam Call Is Probably a Houston Spoof—Here is Why

You’re sitting at dinner, your phone vibrates on the table, and you see a number starting with 346. It looks local if you're in Southeast Texas. You pick up. Silence. Then, a click. A robotic voice starts rambling about your "expired car warranty" or a "suspicious charge on your Amazon account." It’s annoying. Actually, it’s more than annoying; it’s a constant digital trespass.

The 346 area code isn't inherently evil. It’s just a Houston overlay. Since 2014, it has served the same massive footprint as 713, 281, and 832. But for some reason, area code 346 spam has exploded lately. Scammers love it because it carries the "neighbor effect." When you see a 346 number, your brain registers it as a person in a suburban Houston office or a neighbor in Sugar Land, not a call center in a different hemisphere.

Why 346 Numbers Are a Goldmine for Scammers

Scammers aren't random. They are calculated. They use VoIP (Voice over Internet Protocol) technology to "spoof" their caller ID. This means they can make a call from anywhere in the world and force your phone to display a 346 number.

Why 346? Because it’s newer. While many people have blocked the older 713 or 281 sequences, 346 still feels fresh enough to be a legitimate new business or a friend who just moved to Katy. According to data from call-blocking services like YouMail and Hiya, Houston consistently ranks in the top five most targeted cities for robocalls in the United States. In some months, Houstonians receive over 100 million spam calls. That is a staggering amount of noise.

The "neighbor spoofing" tactic relies on a simple psychological trick: familiarity. You’re 20% more likely to pick up a call if the area code matches your own or a nearby region. The scammers know this. They buy blocks of 346 numbers or just spoof them entirely to bypass the "Scam Likely" filters that carriers like T-Mobile or Verizon try to maintain.

The Most Common 346 Scams Hitting Your Phone Right Now

It’s rarely a "wrong number." Most of these calls follow a script. Honestly, they’re pretty predictable once you know what to listen for.

The "Public Utility" Threat
This one is big in Houston. You’ll get a call from a 346 number claiming to be from CenterPoint Energy or a similar local utility. They tell you your power will be cut off in 30 minutes unless you pay a "past due balance" via a prepaid debit card or Zelle. It's a lie. Real utility companies don't call you to demand immediate payment via gift cards. Ever.

The Amazon/ICD Order Fraud
"Your account has been charged $799 for a Macbook Pro." That’s the hook. They want you to panic. They want you to press "1" to talk to a "representative" who will then ask for your login credentials or remote access to your computer to "cancel" the order.

The Medicare/Health Insurance Push
Since Houston has a massive medical center and a large elderly population, 346 numbers are frequently used to peddle fraudulent back braces or "free" medical screenings. These are often fishing expeditions for Social Security numbers.

The Technical Reality of VoIP Spoofing

We need to talk about how this actually happens. It isn't a guy with a bunch of cell phones. It’s a server. Using SIP (Session Initiation Protocol) trunking, a scammer can generate thousands of calls per second.

The FCC has tried to fight this with the STIR/SHAKEN framework. This sounds like a James Bond reference, but it's actually a set of technical standards. Basically, it’s supposed to "sign" calls so your carrier knows they are legitimate. But there’s a loophole: "gateway" providers. Smaller, less regulated phone companies often let these calls onto the US network without proper verification. That’s why your phone still rings even though the government said they "fixed" the problem years ago.

How to Tell if a 346 Call is a Scam

You can't always tell by the number alone. But the behavior of the caller is a dead giveaway.

  1. The "Can you hear me?" trick. If they start with this, hang up. They want a recording of you saying "Yes" to authorize fraudulent charges later.
  2. Sense of Urgency. If the voice on the other end is rushing you, threatening arrest, or claiming an "emergency," it’s 99% a scam.
  3. The "Dead Air" Pause. Scammers use autodialers. When you pick up, the system takes a second to route the call to a human. If you say "Hello" and there is two seconds of silence before someone speaks, just hang up.

Real Solutions to Silence the 346 Spam

Stopping area code 346 spam requires a multi-layered defense. You can't just block one number because the scammers will just use a different one five minutes later.

Carrier-Level Blocking

Most major carriers have free apps that are actually decent.

  • AT&T ActiveArmor: Blocks known fraud calls before they even ring.
  • T-Mobile Scam Shield: Provides a "Scam Block" feature that you can toggle on.
  • Verizon Call Filter: Identifies and filters out high-risk callers.

Third-Party Apps

If your carrier isn't doing enough, look at apps like RoboKiller or Hiya. RoboKiller is interesting because it uses "answer bots" to waste the scammer's time. It answers the call with a recording of a confused person, keeping the scammer on the line so they can't call someone else. It’s a bit of digital karma.

Phone Settings (The "Nuclear" Option)

If you’re fed up, go to your iPhone settings and turn on "Silence Unknown Callers." On Android, it’s "Block numbers from unknown callers." This will send any call from a number not in your contacts straight to voicemail. If it’s a real person from a 346 number, they’ll leave a message. If it’s a robot, they won't.

It feels like the law is toothless here. The Telephone Consumer Protection Act (TCPA) exists, and the FCC hands out massive fines—sometimes in the hundreds of millions of dollars. But here is the problem: the people making these calls are often in jurisdictions where US law doesn't matter.

Think of it like a game of whack-a-mole. The FCC shuts down one "gateway" provider in Florida, and two more pop up in Eastern Europe or Southeast Asia the next day. The cost of making these calls is essentially zero. Even if only one out of 10,000 people falls for the "IRS" or "Amazon" scam, the criminals make a profit.

Actionable Steps to Protect Your Data

You should treat your phone number like your Social Security number. Don't give it out to every website that asks for it.

  • Use a Google Voice number for online shopping or public forms. It’s free and has its own spam filtering.
  • Never hit "2" to be removed. On a spam call, this just tells the computer that your number is "active," which makes it more valuable. They will sell your number to even more scammers.
  • Report the number. Use the FTC’s Report Fraud website. While it won't stop the next call, it helps the government track which providers are letting the most spam through.

The 346 area code is a part of Houston's identity now. It's too bad it has been hijacked by bad actors. By understanding that these calls are almost always spoofed and using the "silence unknown" settings on your device, you can reclaim your peace of mind.

Check your "Recent Calls" list right now. If you see a string of 346 numbers you don't recognize, don't call them back out of curiosity. It’s just a bot waiting for a live human to engage. Block them, report them, and move on with your day.


Immediate Next Steps for Protection:

  1. Enable "Silence Unknown Callers" in your phone’s system settings to immediately stop the ringing.
  2. Download your carrier’s official security app (Scam Shield, ActiveArmor, or Call Filter) to verify if the 346 calls are flagged as "Potential Spam."
  3. Register your number on the National Do Not Call Registry, though keep in mind this only stops legitimate telemarketers, not actual criminals.
  4. Audit your "Blocked Contacts" list once a month to ensure you haven't accidentally silenced a legitimate local business you actually need to hear from.
