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.
Where 817 reaches — Fort Worth + the western Metroplex
The 817 / 682 footprint is anchored on Fort Worth and stretches out across:

- The HEB cities — Hurst, Euless, Bedford — three small contiguous suburbs (~150k combined).

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.

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