Houston is a city defined by its constant growth and dynamic energy. As millions of people have flocked to the metro area, the demand for new phone numbers has surged, leading to the introduction of new area codes. If you’ve recently seen a call from the 346 area code, you might be curious about where it’s from and who might be calling.
This number is a core part of Houston’s telecommunication network, serving residents and businesses across the sprawling metropolis. People look up this code for many reasons, from verifying a local business to checking if an unknown call is a potential scam. Let’s see where the 346 area code comes from and why it matters to Houston.
What is the 346 Area Code?
An area code is the three-digit prefix that identifies a specific geographic region within a larger telephone network, as managed by the North American Numbering Plan Administrator (NANPA). The 346 area code is one of several codes serving Houston, Texas, and its surrounding communities.
It functions as an “overlay” area code. An overlay is introduced when an existing area code runs out of available phone numbers. Instead of splitting the geographic region into two separate zones, a new code is added to cover the exact same area. This means multiple area codes can serve the same neighborhood. In Houston, the 346 area code shares its territory with the 713, 281, and 832 codes, ensuring the region has enough phone numbers for its growing population.
Here is a quick comparison of Houston’s primary area codes:
| Area Code | Introduced | Type | Key Cities Served |
|---|---|---|---|
| 713 | 1947 | Original | Houston (primarily inside Loop 610 initially) |
| 281 | 1996 | Overlay | Pasadena, Sugar Land, Baytown |
| 832 | 1999 | Overlay | Katy, Pearland, The Woodlands |
| 346 | 2014 | Overlay | Greater Houston Metro Area |
| 621 | 2025 (Planned) | Overlay | Future Use for the entire Houston area |
The History of Houston’s Area Code Overlay System
Houston’s journey through multiple area codes tells a story of incredible expansion. For nearly 50 years, one code was enough to serve the entire region. But as the city boomed, so did the need for more phone lines, fax machines, and eventually, mobile devices.
The area’s population growth, now at approximately 7.4 million people in the metro area as of 2024, drove the need for this multi-layered system. Projections from the FCC and the Texas Public Utility Commission (PUC) consistently showed that number exhaustion was imminent, prompting the addition of new codes to keep the city connected.
Here’s a brief timeline of how Houston’s area codes evolved:
- 1947: The original 713 area code is established, covering Houston and its nearby towns.
- 1996: To address number shortages, the 281 area code is created. It initially formed a ring around the central 713 zone.
- 1999: The system shifts again. The 832 area code is introduced as an overlay for the entire 713/281 region, and 10-digit dialing becomes mandatory for all local calls.
- 2014: With continued growth, the 346 area code is launched, overlaying the same vast territory as the other three codes.
- 2025: A new overlay, the 621 area code, is planned to be activated to provide another layer of number capacity for the decades to come.

Location and Coverage of the 346 Area Code
The 346 area code doesn’t belong to a single, isolated city. Instead, it blankets the entire Greater Houston metropolitan area. If you get a 346 number, you could be anywhere from the bustling downtown core to a quiet suburban neighborhood.
Major cities and towns where you will find the 346 area code include:
- Houston
- Pasadena
- Pearland
- Katy
- Sugar Land
- The Woodlands
- Cypress
- Baytown
- Tomball
- Spring
This territory spans several major counties, including Harris, Fort Bend, Montgomery, Brazoria, Galveston, and Liberty counties. Within Houston itself, a 346 number is just as likely to belong to someone in affluent River Oaks as it is to a business in the vibrant cultural hubs of Midtown or The Heights.
Time Zone and Dialing Information
All phone numbers within the 346 area code operate on the Central Time Zone (CT).
- During standard time, it is on Central Standard Time (CST).
- During Daylight Saving Time, it switches to Central Daylight Time (CDT).
In 2025, Daylight Saving Time begins on March 9 and ends on November 2.
Because 346 is part of an overlay system, 10-digit dialing is mandatory for all local calls. This means you must dial the full area code + seven-digit number, even if you are calling your next-door neighbor. A call from a 346 number to a 713, 281, or 832 number is still a local call, not a long-distance toll call. This rule applies to landlines, mobile phones, and VoIP systems alike.
Common Scams and How to Handle Unwanted 346 Calls
Unfortunately, the prevalence of numbers from large metro areas makes codes like 346 a target for scammers. Scammers use technology to “spoof” local numbers, making it appear that a call is coming from your area to increase the chances you’ll answer. The FTC noted in 2024 that codes from major cities like Houston are frequently used in these schemes.
Some common scams associated with spoofed 346 numbers include:
- “Hello?” Bait Calls: Scammers call and say nothing, waiting for you to speak. They may be using a robocaller to verify that your number is active for future scam attempts.
- Impersonation Scams: Callers pretend to be from the IRS, Social Security Administration, or a local utility company, demanding immediate payment to avoid penalties or service disconnection.
- Delivery Text Scams: You receive a text message, seemingly from a service like FedEx or Amazon, claiming there’s an issue with a delivery. The message includes a phishing link designed to steal your personal information.
- Phishing Links: Both calls and texts may try to direct you to malicious websites that mimic legitimate businesses to capture your login credentials or financial details.
Spoofing makes it easy for a scammer anywhere in the world to appear as if they are calling from Houston. This anonymity is why it’s crucial to be cautious with any unsolicited call.
How to Block and Report Spam Calls
You have several tools at your disposal to fight back against unwanted calls from spoofed 346 numbers.
- Use Your Phone’s Built-in Features: Both iPhone and Android devices allow you to block individual numbers directly from your recent calls list. For a more robust solution, enable the “Silence Unknown Callers” feature on your iPhone or a similar call-screening function on your Android.
- Leverage Carrier Filters: Major carriers offer free services to help filter spam. Check out AT&T Call Protect, Verizon Call Filter, or T-Mobile’s Scam Shield.
- Download Third-Party Apps: Apps like Truecaller, Hiya, and RoboKiller use global databases to identify and block known spam numbers before your phone even rings.
- Report Scams: Help authorities track and stop scammers by reporting unwanted calls and texts to the FTC Complaint Assistant and the Texas Attorney General’s office.
Why Your Business Needs a Houston (346) Area Code Number
For businesses operating in or targeting the Houston market, having a local phone number is a powerful asset. Research shows that people are far more likely to answer calls from a local number—some studies indicate up to 83% of individuals prefer it over a toll-free or out-of-state number. A 346 area code number instantly establishes a local presence, building trust with potential customers.
Getting a local number is both easy and affordable, thanks to Voice over Internet Protocol (VoIP) providers. For as little as $5 to $15 per month, services like Dialpad, Tresta, and Grasshopper can provide your business with a 346 number packed with features like call routing, voicemail transcription, and analytics. This also boosts your local SEO, as search engines often use phone numbers to verify a business’s location for “near me” searches.
How to Get a 346 Area Code Number
Securing a 346 number for your business or personal use is a straightforward process with a VoIP provider.
- Choose a Provider: Select a VoIP service that fits your needs. Popular options include Aircall, Tresta, and Dialpad.
- Search for Numbers: Use the provider’s online portal to search for available phone numbers with the 346 area code.
- Complete Verification: Provide your business or personal information to register the number.
- Configure Your Settings: Set up features like call forwarding, business hours, and a professional voicemail greeting.
- Port Your Existing Number (Optional): If you already have a number you want to keep, most providers can port it to their service for free. This process typically takes 3-5 business days.
Keep in mind that a 346 number is a standard local line, not a toll-free number. Callers from outside the Houston local calling area may incur long-distance charges.
