817 Area Code: Fort Worth, Texas — Cities, Overlay & Business Guide

The 817 area code is the telephone code for Fort Worth, Texas, and the western half of the Dallas–Fort Worth metroplex — all of Tarrant County plus surrounding Johnson, Parker, Hood, and Wise counties, on Central Time.

It has served the region since 1953, and it remains the number locals associate with Sundance Square, the museum row of the Cultural District, and the historic Stockyards where cattle drives still move down Exchange Avenue. From downtown office towers to the stadium lights of Arlington, an 817 number signals genuine Tarrant County roots.

This guide explains what the 817 area code covers, which cities and districts sit inside it, how the 682 overlay changed local dialing, where the neighboring Dallas and North Texas codes begin, what powers the Fort Worth economy, and the exact steps a business anywhere can follow to activate an 817 number without opening a local office.

817 is the North American Numbering Plan code assigned to Fort Worth, Arlington, and the surrounding communities of Tarrant County in North Texas. It was carved out of the original 214 territory in 1953, when the Dallas–Fort Worth region had grown too large for a single code, and it has anchored the western side of the metroplex ever since.

Today the code shares its footprint with the 682 overlay, which means every local call is dialed with the full ten digits.

• Dialing format: (817) 555-0123
• International format: +1 817-555-0123
• Time zone: Central Time (CT) — UTC−6 Standard, UTC−5 Daylight Saving
• Year introduced: 1953

The code covers Fort Worth itself along with Arlington and a ring of Tarrant County communities between the two cities. The footprint stretches from historic districts north of downtown to the entertainment corridor along Interstate 30, taking in office parks, rail yards, universities, and some of the most visited attractions in Texas.

Downtown

Downtown Fort Worth centers on Sundance Square, a walkable district of restored early-twentieth-century buildings filled with offices, theaters, restaurants, and plazas. It is the civic and commercial heart of the code, home to corporate headquarters, the convention center, and the courthouse that closes the view down Main Street.

Cultural District

West of downtown, the Cultural District is Fort Worth's museum row — a cluster of internationally regarded art and science museums set among gardens and boulevards. The district also hosts the annual stock show and rodeo, blending fine art with the city's western heritage in a way few American neighborhoods can match.

Stockyards

The Stockyards National Historic District preserves the brick streets, cattle pens, and saloons of Fort Worth's livestock era. Twice-daily cattle drives, western-wear shops, and honky-tonk music halls make it one of the most recognizable places carrying the prefix, and a working reminder of how the city earned the nickname Cowtown.

Arlington

Arlington sits between Fort Worth and Dallas and serves as the metroplex's entertainment hub. Major-league ballparks, a landmark football stadium, and one of the country's original theme parks sit within a few miles of each other, alongside a large public university and a long-standing automotive assembly presence.

Counties and Communities the 817 Code Serves

Beyond the Fort Worth–Arlington core, the prefix reaches across the western metroplex counties. Anyone checking whether a local number will land in the right market can use the list below as a quick reference for the cities the code covers.

• Tarrant County — Fort Worth, Arlington, Mansfield, Grapevine, Euless, Bedford, and North Richland Hills
• Johnson County — Cleburne and Burleson
• Parker, Hood, and Wise counties — Weatherford, Granbury, and Decatur
• Shared 682 overlay territory — every community above can also receive a 682 number on the identical footprint

Growth across Tarrant County eventually consumed the supply of new 817 prefixes, so regulators added 682 as an overlay rather than splitting the region. The overlay covers exactly the same territory, which means a neighbor, a competitor, or a second line in the same building may carry 682 while established numbers keep 817. Because two codes share one map, ten-digit dialing is mandatory for every local call.

The eastern half of the metroplex belongs to Dallas, where 214, 972, and the 469 area code layer over one another in a three-way overlay serving Dallas and its suburbs. To the north and west, the 940 code covers North Texas communities such as Denton and Wichita Falls. Crossing between these codes is not a long-distance event — the whole metroplex dials ten digits and shares one local calling culture.

• 682 — the overlay sharing the exact same Fort Worth–Arlington footprint as 817
• 214 / 469 / 972 — the Dallas-side codes covering the eastern metroplex
• 940 — North Texas, including Denton and communities toward the Red River

The code observes Central Time (CT) — UTC−6 during Standard Time and UTC−5 during Daylight Saving Time, which runs from mid-March to early November. Fort Worth keeps the same clock as Chicago, Houston, and the rest of the American heartland.

Central Time is a practical scheduling position for a business line. Mornings overlap comfortably with the East Coast and afternoons still catch California working hours, so a Fort Worth number can serve customers coast to coast inside a single business day without anyone taking calls at odd hours.

Fort Worth pairs its western heritage with heavyweight industry. The city builds aircraft, moves freight for much of the continent, and manages energy operations across Texas basins — and companies courting that market often begin by putting a local business phone number in front of Tarrant County customers, because a familiar prefix earns the first callback.

Aviation & Defense

Fighter jets are assembled on the west side of the city, and major airline headquarters sit within the metroplex, making aviation the region's signature industry. Defense contractors, avionics suppliers, and maintenance specialists cluster around these anchors, drawing engineering talent from across the country to Tarrant County.

Rail & Logistics

One of the nation's major freight railroads calls Fort Worth home, and the city's rail yards and intermodal terminals help move goods between coasts, the Gulf, and Mexico. Distribution centers and trucking operations fan out from the metroplex, sustained by its position at the crossroads of several interstate corridors.

Energy

Fort Worth sits atop the Barnett Shale, and basin operations and services remain woven into the local economy. Exploration firms, field-services companies, pipeline operators, and the law and finance professionals who support them keep energy a steady pillar of the city's business scene alongside its newer growth industries.

The pattern mirrors the 314 area code, where the St. Louis economy shapes number demand in much the same way.

Cloud phone providers make a Fort Worth number available to any business, anywhere, with no Texas address required. The whole process takes minutes and follows three steps.

1. 1Choose a provider — pick a cloud phone service such as MeraTalk that offers Fort Worth numbers, and create an account online.
2. 2Pick a number — search available 817 numbers and select a combination that is easy for customers to remember.
3. 3Activate and route — complete verification, then point the number at any destination; calls ring on any device, from a desk phone in Arlington to a laptop or mobile app overseas.

Once live, the number works exactly like any local line. Customers dial (817) 555-0123 from within the US, while international callers use +1 817-555-0123, and features such as auto-attendant, call recording, and CRM integration can be layered on from day one.

Reaching Fort Worth from another country follows the standard North American pattern. The caller dials their country's international exit code, then the US country code 1, then the full ten digits beginning with 817. On any mobile phone worldwide, entering +1 817 followed by the seven-digit line number connects directly without needing the local exit code.

• From the UK or most of Europe: 00 + 1 + 817 + seven-digit number
• From Mexico: 00 + 1 + 817 + seven-digit number
• From any mobile phone: +1 817 followed by the seven-digit number

Central Time makes scheduling easy for most international callers. A 4 PM call from London lands at 10 AM in Fort Worth, while callers in Mexico — a major trading partner for the metroplex's rail and manufacturing sectors — share the same or a neighboring clock and can reach Tarrant County businesses throughout the working day.

A familiar Fort Worth prefix on caller ID is exactly what fraudsters count on. Through caller ID spoofing, a scammer anywhere in the world can display a Tarrant County number, betting that residents will pick up what looks like a local school, clinic, or utility.

• Fake toll-road violation calls and texts targeting Texas drivers
• Utility disconnection threats demanding immediate payment by gift card
• Event ticket scams around Arlington's stadium district on game days
• One-ring callback bait designed to trigger costly return calls

The safest habit is simple: treat an unexpected request for money or personal details as suspect regardless of the caller ID, hang up, and call the organization back on its published number. Suspicious calls can be reported to the FCC or FTC, and carrier-level spam filtering blocks many of them automatically.
