940 Area Code: North Texas From Wichita Falls to Denton

Introduction

The 940 area code answers across North Texas — the counties that fan out north and northwest of the Dallas-Fort Worth metro, from the Red River down to the edge of the suburbs. It is the number that rings in Wichita Falls, on the Denton campuses, and across the ranchland and oil country in between.

This guide maps where the 940 prefix reaches, the industries that shape it — a major Air Force base, two university towns, and a deep agriculture-and-energy base — its Central Time calling window, its 1997 origin as a split from Fort Worth, and how to put a North Texas number in front of customers in minutes.

Where the 940 Area Code Reaches

The 940 area code covers North Texas, the band of counties sitting north and northwest of the Dallas-Fort Worth metro. It is a mix of two mid-sized anchor cities and a wide rural footprint of farms, ranches, and small towns.

• Wichita Falls — the largest city in the region, home to Sheppard Air Force Base and Midwestern State University
• Denton — the fast-growing university city on the northern edge of the DFW metro
• Gainesville — the Cooke County seat near the Red River and the Oklahoma line
• Vernon — the Wilbarger County seat anchoring the far northwest ranchland
• Nocona — the Montague County town long tied to leather goods and ranching

Because the footprint pairs university towns with open country, an area code 940 line can signal either a campus-city business in Denton or a working ranch-and-energy presence out toward Vernon. One prefix carries both identities across North Texas. The 817 area code guide covers the neighbouring ground.

Wichita Falls, Sheppard AFB, and the Regional Economy

Wichita Falls anchors the western half of the 940 area code as its largest city, built on a mix of military, education, and manufacturing. It sits near the Red River, roughly two hours northwest of Fort Worth.

Sheppard Air Force Base

Sheppard Air Force Base is the economic engine of Wichita Falls, one of the largest training installations in the Air Force. It hosts pilot training and technical schools that bring thousands of personnel, instructors, and contractors through the city each year.

Midwestern State University

Midwestern State University adds a public higher-education base to Wichita Falls, drawing students and faculty into the local economy. Together with regional healthcare and light manufacturing, the university keeps the western 940 area code market steady year-round. More detail sits on our Texas area codes page.

Denton, UNT, and the University Economy

Denton anchors the southern end of the footprint on the northern edge of the DFW metro. It is one of the fastest-growing cities in the region, powered by two large public universities and a lively music and arts scene.

University of North Texas and Texas Woman's University

The University of North Texas and Texas Woman's University together enroll tens of thousands of students in Denton, making higher education the dominant local employer. The campuses feed a professional workforce into the wider metro while keeping the city's own economy young and expanding.

For a business working the whole region, the 940 area code sits directly against Fort Worth's 817 area code to the south, and a full Texas area codes breakdown maps how the North Texas prefixes fit together.

Agriculture, Ranching, and the Rural North Texas Base

Beyond the two anchor cities, agriculture and ranching define much of the area code 940 footprint. The counties toward Vernon, Gainesville, and Nocona run on cattle, wheat, cotton, and the farm-and-ranch supply businesses that serve them.

Livestock auctions, feed and equipment dealers, and family ranching operations fill the rural stretches of North Texas. For these businesses, a familiar local number is how buyers, haulers, and suppliers recognize a caller as part of the regional trade rather than an outside cold call. An area code 940 line, rooted in these ranching and farm-supply communities, quietly tells a buyer that the caller understands the local market, its seasons, and the people who work it every day.

Oil, Gas, and Energy in North Texas

Oil and gas run through the 940 economy alongside agriculture, with production, service companies, and pipeline operations spread across the region. North Texas has a long history in energy, and the sector still supports drilling crews, field-service vendors, and equipment suppliers.

The state's official portal at texas.gov lists the agencies, permits, and business filings that govern Texas energy operators, ranchers, and vendors across the region.

Time Zone and Calling Hours for the 940 Area Code

The entire 940 area code observes Central Time — UTC-6 (CST) in winter and UTC-5 (CDT) during Daylight Saving. North Texas shares the clock with Dallas, Fort Worth, and the rest of the Central time band.

East Coast teams calling area code 940 are one hour ahead, so mid-morning outbound campaigns on the Eastern seaboard land comfortably inside the North Texas business day — plan around the single-hour gap.

940 History

The 940 area code was created in 1997 as a split from the Fort Worth 817 code. As wireless lines and second numbers drained the supply through the 1990s, the North Texas counties outside the Fort Worth metro were carved off into a new prefix.

Fort Worth and its immediate suburbs kept 817, while Wichita Falls, Denton, and the surrounding rural counties moved to 940. The split gave the growing North Texas region its own dedicated numbering space.

How to Get a 940 Area Code Number

1. 1Cloud phone platform — search available 940 numbers in real time and activate a line the same day, with no hardware and no technician visit.
2. 2Port your existing number — already run a 940 line on another carrier? Move it over without downtime and keep the number active through the transition.
3. 3Wireless SIM or landline carrier — valid for a single physical handset, but slower to provision and harder to scale seat by seat.

With letsdial, a 940 number provisions in under three minutes on a free trial, no credit card required, so a North Texas presence can be answering calls the same afternoon.

Call Trust in the North Texas Market

The 940 area code market runs on ranch-supply relationships, campus vendor channels, and base-area procurement — settings where an unknown out-of-state number gets screened before it is answered. A recognizable local prefix earns the first hearing, and in a region that fields constant cold outreach, that first impression often decides whether the conversation happens.

STIR/SHAKEN for Ranching, Education, and Energy

Apply STIR/SHAKEN attestation so every outbound 940 call arrives verified with your registered business name on screen. Register text campaigns for 10DLC compliance from day one and warm new numbers before scaling volume. With letsdial, a verified line that displays a real business name reads as North Texas-local rather than out-of-area.

A trusted 940 line is the difference between a ranch buyer or a base-area procurement officer picking up and routing the call straight to voicemail. That record is published in full as texas.gov.

Conclusion

The 940 area code covers a wide, working stretch of Texas — a major Air Force base, two busy university towns, and the ranch-and-energy country that runs between them. From Sheppard Air Force Base to the Denton campuses and the ranchland toward Vernon, it identifies a business as genuinely North Texan.

Standing up a line takes minutes on a cloud platform, with STIR/SHAKEN attestation so calls arrive verified rather than flagged. Put a North Texas number in front of ranchers, campus buyers, and energy vendors, and let a familiar prefix open the door before the first word.
