If you’ve ever gotten a call from a number starting with 817, you were likely being contacted by someone in the heart of North Texas. But the 817 area code is much more than just a three-digit prefix—it’s the primary telephone identifier for the western half of the Dallas-Fort Worth Metroplex, anchored by the historic and rapidly growing city of Fort Worth.
In this guide, we’ll break down everything you need to know about the 817 area code, from its fascinating history and geographic reach to the current telecommunications landscape and common scams to watch out for.
Where is Area Code 817 Located?
The 817 area code is located in north-central Texas, serving most of the western portion of the Dallas-Fort Worth Metroplex. The largest and most prominent city within its coverage is Fort Worth, often referred to as “Cowtown” due to its rich Western heritage. Beyond Fort Worth, 817 is the area code for a diverse mix of cities, including Arlington, Mansfield, Grapevine, and North Richland Hills.
The region operates on Central Time (CT). This means it follows Central Standard Time (CST, UTC-6) during the fall and winter and switches to Central Daylight Time (CDT, UTC-5) in the spring and summer to observe Daylight Saving Time. So, if you’re doing business with someone in the 817 area, be sure to account for that time difference.
The History of the 817 Area Code
The story of area code 817 is a testament to the explosive growth of Texas. It was created in 1953 when the eastern half of the original area code 915 was split off, with small portions possibly coming from area code 214. At the time, 817 covered a massive swath of central Texas, stretching to the Red River.
As the Dallas-Fort Worth Metroplex boomed in the late 20th century, the region’s need for new phone numbers grew exponentially. On July 25, 1997, area code 817 was drastically reduced in a three-way split. The northern portion of its territory, including Wichita Falls and Denton, became area code 940, while the southern portion, including Waco and Killeen, became area code 254. This reduced 817 to essentially its current footprint around Fort Worth.
However, the region’s rapid growth didn’t stop. Just a few years later, the 817 area code was once again at risk of running out of numbers. To solve this, area code 682 was introduced on October 7, 2000, as an overlay for the entire 817 territory.
Major Cities and Counties in the 817 Area Code
Today, the 817 area code (alongside its 682 overlay) covers a dynamic region that includes several counties and dozens of cities. Here’s a breakdown of its coverage:

Economic Significance and Local Culture
The 817 area code is a major economic engine for Texas. Fort Worth alone has emerged as one of the fastest-growing cities in the United States, nearly doubling its population since 2000. It is home to several major corporations, including American Airlines, GM Financial, and significant operations for Lockheed Martin and AT&T. Meanwhile, Arlington houses the University of Texas at Arlington (UTA) and the massive GM Assembly plant.
Culturally, the region offers a unique blend of the Old West and modern sophistication. Fort Worth’s cowboy culture is on full display at the Fort Worth Stock Show and Rodeo, the longest-running event of its kind in the country. At the same time, its renowned Cultural District features the Modern Art Museum and the Kimbell Art Museum, cementing its reputation as the “City of Cowboys and Culture”.
Scams and Spam Calls: Staying Safe in the 817
Like many high-growth metropolitan areas, the Dallas-Fort Worth region is a major target for phone scams. The 817 area code is frequently used by scammers through a practice known as “neighbor spoofing,” where they fake a local number to trick you into answering.
Data shows that over 82 million robocalls have been placed to 817 numbers in 2026 so far, which equates to roughly 42.7 calls per person affected.
Here are some of the most common 817 area code scams to be aware of:
-
Social Security Arrest Scams: Callers pretend to be from the Social Security Administration, threatening arrest or freezing your bank account due to fraudulent activity.
-
Fake Lawsuit Threats: Scammers claim to be process servers with legal documents for you, creating panic to extort money or information.
-
Auto Warranty Robocalls: Pre-recorded messages claiming your car’s warranty is about to expire, pressuring you to make an immediate payment.
Safety Tip: If you receive an unsolicited call from an unknown 817 number, do not answer it. If the call is legitimate, the person will leave a voicemail. Never give out personal information or payment details over the phone to an unsolicited caller.
Telecommunications Today: The 682 Overlay and 10-Digit Dialing
Because area code 682 is an overlay (meaning it covers the exact same geographic area as 817), it is now mandatory to dial all 10 digits (the area code + the 7-digit number) for every local call you make within the region. You can no longer dial just 7 digits. This is a permanent change that ensures the region continues to have a sufficient supply of phone numbers for its growing population and businesses.
If you’re a business owner looking to establish a local presence in Fort Worth or the surrounding area, securing a phone number with the 817 area code is a powerful way to build trust and credibility with local customers.
Conclusion
The 817 area code is more than just a number; it’s a symbol of the dynamic, historic, and rapidly expanding western half of the Dallas-Fort Worth Metroplex. From its origins as part of a massive territory in 1953 to its modern-day overlay with 682, the story of 817 is the story of Texas growth itself. Whether you’re a resident, a business owner, or just someone who received a call from “Cowtown,” understanding this area code gives you a unique glimpse into one of the most vibrant regions in the United States.
Frequently Asked Questions About the 817 Area Code
1. Is area code 817 a toll-free number?
No. It is a standard local geographic area code for north-central Texas. Calls to an 817 number are treated like any other local or long-distance call, depending on your phone plan and location. It is not toll-free like 800, 833, 844, etc.
2. Do I have to dial 10 digits for 817 numbers?
Yes. Because the 682 area code overlays the exact same region as 817, 10-digit dialing (817 + the 7-digit number) is required for all local calls, even if both parties have 817 numbers. Dialing just 7 digits will not complete the call.
3. What time zone is the 817 area code in?
It follows Central Time (CT) – Central Standard Time (CST, UTC-6) from November to March, and Central Daylight Time (CDT, UTC-5) during daylight saving time (March to November).
4. Is area code 817 the same as 682?
No, but they serve the same region. 817 is the original area code for Fort Worth and western DFW. 682 was added in 2000 as an overlay, meaning new phone numbers in the same geographic area are assigned either 817 or 682. Both codes coexist and cover the exact same cities.
5. How can I get a phone number with the 817 area code?
You can request an 817 number from most major phone carriers (AT&T, Verizon, T-Mobile, Spectrum, etc.), as well as VoIP providers like Google Voice, RingCentral, or Grasshopper. Availability depends on current number inventory. Businesses often choose 817 to establish a local Fort Worth presence.
6. Is the 817 area code only for cell phones?
No. 817 serves all types of phone lines – landline, cell phone, VoIP, and business lines. Like all geographic area codes, numbers are assigned without regard to device type.
7. What should I do if I get a spam call from an 817 number?
Do not answer if you don’t recognize the number. If you do answer and it’s a robocall or scam, hang up immediately. You can block the number and report it to the FTC (ftc.gov/complaint) or the FCC. Using a call-blocking app or your carrier’s spam filter can also help.
8. Why do I keep getting calls from 817 numbers if I don’t live in Texas?
Scammers often use neighbor spoofing – they fake a local-looking area code (like 817) to trick you into answering, even if you live elsewhere. If you have no connection to Fort Worth, these are almost certainly spam calls. Ignore or block them.
9. Will the 817 area code run out of numbers?
It was close to exhaustion in the late 1990s, which led to the introduction of the 682 overlay in 2000. With 10-digit dialing and two codes sharing the same territory, the region has a much larger pool of numbers. However, due to continued population growth, additional overlays or relief measures could be considered in the distant future.
10. What are the most famous landmarks in the 817 area code?
Some of the most iconic include:
-
Fort Worth Stockyards (historic cattle drives)
-
AT&T Stadium (Dallas Cowboys, Arlington)
-
Globe Life Field (Texas Rangers, Arlington)
