817 Area Code: The Number That Says Fort Worth

Quick answer: The 817 area code covers Fort Worth and Tarrant County — the western half of the Dallas–Fort Worth Metroplex. That includes Fort Worth, Arlington, Mansfield, Grapevine, the HEB cities (Hurst, Euless, Bedford), Keller, North Richland Hills, Burleson, plus the outer counties of Johnson (Cleburne), Parker (Weatherford), and Hood (Granbury). It's been the Fort Worth code since 1953, sits in Central Time, and shares its territory with the 682 overlay (added in 2000). 10-digit dialing is required for every local call.

What is the 817 area code?

If you've ever pulled up a Fort Worth number on caller ID, the chances are it started with 817.

It's the original area code for the western half of the DFW Metroplex — Tarrant County and the suburban + rural counties just beyond it.

This guide comes from My Country Mobile (MCM), a virtual phone provider that issues local numbers across the US.

A few facts that make 817 stand out from the broader DFW numbering landscape:

• Original code since 1947 — 817 was one of the NANP's founding area codes, assigned to all of Texas west of the Dallas corridor at launch.
• Shared with 682 — the 682 overlay was added in 2009 when 817 approached exhaustion; both codes cover the identical territory today.
• Tarrant County anchor — Fort Worth, Arlington, and the surrounding suburbs form the densest concentration of 817 lines in the state.
• Distinct from Dallas — Dallas proper runs on 214 and 972; an 817 number signals western Metroplex, not downtown Dallas.

Where 817 reaches — Fort Worth + the western Metroplex

The 817 / 682 footprint is anchored on Fort Worth and stretches out across:

Tarrant County (the core)

• Fort Worth — Tarrant County seat, 5th-largest city in Texas (~950,000 people). Home of the Stockyards, TCU, Texas Wesleyan, and the western half of DFW International.
• Arlington — between Fort Worth and Dallas (~395,000 people). AT&T Stadium (Cowboys), Globe Life Field (Rangers), Six Flags Over Texas, UT Arlington.
• Mansfield — fastest-growing Tarrant suburb (~75,000). Top-rated school district.
• Grapevine — DFW Airport-side town (~50k). Main Street historic district.
• The HEB cities — Hurst, Euless, Bedford — three small contiguous suburbs (~150k combined).
• Keller, North Richland Hills, Burleson, Crowley, Saginaw, Watauga, Colleyville, Southlake, Trophy Club, Roanoke, Westlake.

Outer counties

• Johnson County — Cleburne, Burleson edges, Joshua, Alvarado.
• Parker County — Weatherford, Aledo, Willow Park.
• Hood County — Granbury, Tolar.
• Wise County — Decatur, Bridgeport.
• Palo Pinto County — Mineral Wells.

How 817 and 682 work together

The Fort Worth side of the Metroplex went on a single area code for 47 years. Then in 2000, regulators layered a second code on top:

1953: 817 splits from 214

When Texas got its second area code, 817 was carved out of 214 (Dallas) to give Fort Worth and the western Metroplex their own identity.

2000: 682 overlay added

By the late 1990s, mobile phones, fax lines and exurban growth pushed 817 toward exhaustion. Rather than re-carve the region, the Texas PUC added 682 as an overlay on top of 817 — same territory, second pool of numbers.

What it means for you

• Existing 817 numbers stayed 817. Nobody renumbered.
• New numbers issued after 2000 can come from either pool. Today, most fresh western-DFW lines are 682.
• A 682 number is not "lesser" than 817 — they cover identical geography.
• 10-digit dialing is mandatory for every local call.

The 817 time zone

817 runs on Central Time — the same clock as Chicago, Houston, and Mexico City.

• Central Standard Time (CST): UTC−6 (winter)
• Central Daylight Time (CDT): UTC−5 (summer)

Reference clock — when it's 12:00 PM in 817 (Fort Worth):

For outbound calls to 817 from the East Coast, target 10 AM to 6 PM Eastern to land inside a Fort Worth workday.

Why an 817 number helps your business

A 817 line tells a Tarrant County customer you're part of the western DFW community — not a faraway call center.

• Higher pickup rates on outbound. Familiar local prefixes get answered; unknowns go to voicemail.
• Geo-targeted ads land harder when the call-back number is local. An 817 on a billboard reads as a neighbor.
• Vanity numbers double as advertising — 817-COWBOYS, 817-FORTWORTH, 817-ARLINGTON, 817-MANSFIELD.

Fort Worth sits at a crossroads of industries that all rely on local trust: defense contractors, aviation-adjacent businesses, healthcare systems, and a booming logistics hub along I-35W. In each of these sectors, a recognizable 817 prefix can be the difference between a returned call and a missed opportunity.

What a local 817 number does for your bottom line:

• Builds credibility instantly — prospects in Tarrant County recognize 817 as home territory; that familiarity reduces call screening and voicemail drop-off.
• Supports multi-location businesses — hold dedicated lines for Fort Worth, Arlington, and Mansfield without running separate carriers or accounts.
• Pairs with call routing — forward your 817 line to any cell, desk phone, or team softphone, so no lead goes unanswered during peak hours.
• Scales affordably — add additional 817 seats as your team grows, from a solo freelancer to a regional call center.

And because it's a virtual number, you can hold an 817 line while based anywhere with internet.

Fort Worth's economic growth and the 817 opportunity

Fort Worth has been one of the fastest-growing major cities in the United States for the past decade. Understanding the scale of that growth matters for any business evaluating a local 817 presence — a market this size generates demand across nearly every service category.

Fort Worth's population recently crossed one million, making it the fifth-largest city in Texas. The city consistently ranks among the top metros for job creation and corporate relocations. Tarrant County added more than 100,000 residents between 2015 and 2023, with high-growth corridors in Mansfield, Keller, and North Richland Hills pulling in young families and relocating employees.

Key developments driving economic activity across the 817 region:

• Alliance Texas — a 27,000-acre master-planned development in far north Fort Worth hosting distribution centers for Amazon, FedEx, and BNSF Railway, one of the most active industrial corridors in the US Southwest
• Panther Island — a $1.2 billion redevelopment project along the Trinity River expected to generate significant commercial and residential investment through the late 2020s
• Near Southside — Fort Worth's densest employment corridor outside downtown, anchored by major medical campuses and the hospital district employing tens of thousands of Tarrant County residents
• Texas Motor Speedway corridor — NASCAR events and convention traffic along I-35W drive year-round demand for local hospitality, event, and transport businesses

For businesses targeting this market, an 817 number signals that you are part of the Fort Worth community — not an out-of-state vendor. In a city growing this fast, new residents actively seek local service providers across every category. A recognizable area code is often the first credibility signal that gets your call answered rather than ignored.

817 vs 682: choosing the right number for your Fort Worth business

Fort Worth businesses have a choice that most US cities don't offer: two area codes — 817 and 682 — covering the exact same Tarrant County territory. Since both codes reach every western DFW phone identically, the decision comes down to perception, availability, and branding rather than geography.

Why 817 carries more name recognition

817 has been the Fort Worth code since 1953, appearing on decades of business cards, storefronts, and billboards across Tarrant County. When a long-time resident sees 817 on caller ID, the association is immediate — this is a local number. That recognition is a real asset for businesses projecting established local roots.

When 682 makes more sense

682 was added as an overlay in 2000, and most new numbers assigned in western DFW now come from the 682 pool. The prefix is entirely normal for Fort Worth businesses — many of the region's largest employers run 682 lines. For a business launching fresh, a 682 line works just as well operationally and typically offers better vanity number availability.

How to decide between 817 and 682:

• Choose 817 if your brand emphasizes long-standing Tarrant County presence, or if you are targeting established residents who strongly identify with the legacy prefix
• Choose 682 if 817 availability is limited for the number combination you want, or if your audience skews younger and has less attachment to the original code
• Hold both if you operate multiple locations or departments — a dedicated 817 line for Fort Worth proper and a 682 line for Arlington or Mansfield helps route inbound calls more precisely
• Either works for vanity numbers — popular combinations like COWBOYS, FORTWORTH, and ARLINGTON appear in both pools; search live inventory to see what is currently available

Both codes receive identical carrier treatment and STIR/SHAKEN support — no technical difference exists between them. The choice is purely about brand positioning and availability. When unsure, starting with 817 and adding a 682 line later is a low-cost way to test both before committing.

How remote and distributed teams use virtual 817 numbers

A virtual 817 number is not only for businesses located in Fort Worth. Remote teams, out-of-state companies, and distributed workforces can project a credible local presence in Tarrant County without opening a physical office.

How virtual 817 numbers work

A virtual phone number is a cloud-hosted line that forwards calls to any device — a cell phone, desk phone, or softphone app — wherever the recipient is. The caller sees 817 on their caller ID with no indication the person answering is outside Fort Worth. Outbound calls display 817 as well.

Common remote use cases for 817 numbers

• Out-of-state sales teams targeting Tarrant County accounts: carry an 817 line on a cell phone and reach Fort Worth prospects from a number they recognize and are more likely to answer
• E-commerce businesses serving Fort Worth customers: publish an 817 number as your customer service contact so local shoppers reach a familiar local line
• Staffing and recruiting firms placing candidates in the DFW Metroplex: an 817 number signals that you specialize in the Fort Worth market, not a generic national operation
• Field service companies managing Tarrant County technicians: assign dedicated 817 lines to regional coordinators who dispatch jobs without requiring a central Fort Worth office

What to look for in a virtual 817 provider

Look for these capabilities when choosing a virtual 817 provider:

• Flexible call routing — forward calls to different devices or team members by time of day, call volume, or department
• Voicemail-to-email transcription — transcribed voicemails delivered to your inbox so no Fort Worth lead goes unread or unactioned
• Number porting — the ability to bring an existing 817 number to the platform if you already have a local line with established recognition
• STIR/SHAKEN A attestation — verified caller ID so outbound calls are not flagged as spam before a Fort Worth prospect ever has a chance to answer
