Quick answer: Area code 731 is the telephone prefix for West Tennessee, covering Jackson, Dyersburg, Union City, Paris, and Savannah across roughly 20 counties. Created on February 12, 2001, as a geographic split from area code 901, it operates in the Central Time Zone. There is no overlay on 731 — it is the sole area code for the entire region, though ten-digit dialing is still required for every call.
What area code 731 covers across West Tennessee
Area code 731 covers the entire western portion of Tennessee outside the immediate Memphis metro area — a region stretching from the Mississippi River east toward the Tennessee River, and from the Kentucky border south to the Mississippi state line.
Unlike many newer area codes, 731 was created as a geographic split rather than an overlay, meaning it occupies its own dedicated territory with no other code layered on top. Every community inside the 731 boundary uses only this one area code, and no overlay has been introduced since its creation in 2001.
Pairing a 731 number with a 629 area code Nashville presence creates a natural West-to-Middle Tennessee corridor, connecting West Tennessee's agriculture and manufacturing base with Nashville's healthcare, entertainment, and finance economy.

Jackson, Dyersburg, and the cities sharing a 731 number
The 731 territory spans roughly 20 counties across West Tennessee, dividing naturally into a central Jackson corridor, a northwestern lakes region, and a southern river corridor.
Madison County and the Jackson corridor:
- Jackson — The largest city in the 731 territory and the region's commercial, healthcare, and higher-education hub, home to Union University and Jackson State Community College
- Humboldt (Gibson County) and Milan (Gibson County) — Regional agricultural and manufacturing communities
Northwestern lakes region:
- Union City (Obion County) — A manufacturing and logistics center near Reelfoot Lake
- Dyersburg (Dyer County) — Anchored by West Tennessee Healthcare's Dyersburg Hospital and a strong agricultural processing base
- Paris (Henry County) — Home to the annual World's Biggest Fish Fry and gateway to Kentucky Lake
Southern river corridor:
- Savannah (Hardin County) — Located on the Tennessee River, close to the Shiloh National Military Park
- Brownsville (Haywood County) — Near the Toyota Motor Manufacturing megasite and a growing automotive supply chain
- Bolivar (Hardeman County) and Selmer (McNairy County) — Rural manufacturing and agricultural communities
| Sub-region | Key communities |
|---|---|
| Madison County / Jackson corridor | Jackson, Humboldt, Milan, Trenton |
| Northwestern lakes region | Union City, Dyersburg, Paris, Martin |
| Southern river corridor | Savannah, Brownsville, Bolivar, Selmer |
From 901 to 731: West Tennessee's 2001 area code split
Area code 901 was one of the original area codes assigned in 1947, covering the entire western third of Tennessee, including Memphis. For over five decades, 901 served both the dense Memphis metro market and the far more rural counties stretching east toward the Tennessee River.
By the late 1990s, explosive growth in wireless subscriptions across Shelby County was pushing 901 toward exhaustion. Rather than force Memphis itself to split again, the Tennessee Public Utility Commission coordinated with NANPA to carve out the surrounding rural counties into a new code. Area code 731 was activated on February 12, 2001, becoming Tennessee's sixth distinct area code, while 901 was retained exclusively for Memphis and Shelby County.
Because 731 was created as a clean geographic split rather than an overlay, no existing West Tennessee number changed area codes a second time, and the region has needed no additional overlay code since.
| Milestone | Detail |
|---|---|
| 1947 | Area code 901 assigned to all of West Tennessee, including Memphis |
| Late 1990s | Wireless growth in Shelby County pushes 901 toward exhaustion |
| February 12, 2001 | Area code 731 splits off for West Tennessee outside Memphis |
| Today | No overlay has been required since the 2001 split |

Placing a call within the 731 area code
Ten-digit dialing is standard across the entire 731 territory, even for calls between two numbers in the same city.
| Calling scenario | Format |
|---|---|
| Any local call in the 731 territory | 731-XXX-XXXX (ten digits) |
| Anywhere else in the US or Canada | 1-731-XXX-XXXX |
| International call to a 731 number | +1 731 XXX XXXX |
Time zone: The entire 731 territory observes Central Time — the same zone as Memphis, Nashville, and St. Louis. Businesses coordinating between Jackson and the surrounding river and lakes counties never need to account for any time difference within the region.
Why West Tennessee businesses choose a 731 number
A 731 area code number positions a business inside a diverse regional economy spanning automotive manufacturing, food processing, healthcare, and higher education.
Key reasons to establish a 731 area code number:
- Toyota Motor Manufacturing Tennessee and the Memphis Regional Megasite — Automotive assembly and an expanding supplier network across Haywood and surrounding counties support strong demand for logistics, staffing, and industrial services firms
- West Tennessee Healthcare — Anchored by Jackson-Madison County General Hospital and Dyersburg Hospital, the region's largest healthcare network supports a substantial medical, insurance, and professional services economy
- Union University and Jackson State Community College — Jackson's higher-education base drives steady demand in student services, housing, and professional employers
- Agriculture and food processing — Cal-Maine Foods, Tyson Foods, and the West Tennessee Farmers Cooperative anchor a deep grain, poultry, and food-processing supply chain across the region
- UCaaS virtual West Tennessee presence — Businesses targeting the 731 territory's manufacturing, healthcare, or agricultural markets from outside Tennessee can establish immediate Jackson-area credibility through a Unified Communications as a Service (UCaaS) platform, provisioning a 731 number with cloud-hosted voice, video, messaging, and analytics routed to any device worldwide; pairing a 731 number with a 618 area code Southern Illinois presence creates a natural rural manufacturing-and-agriculture corridor connecting two Midwest-adjacent supply chains
Nationwide scam campaigns using 731 area code numbers
Area code 731 is a legitimate telephone prefix serving West Tennessee residents and businesses — but Tennessee ranks among the highest states in the country for robocall complaints per capita, and 731 numbers are frequently spoofed for nationwide campaigns rather than purely local targeting.
Most frequently reported 731 scam types:
- Debt reduction and relief robocalls — The dominant complaint category tied to 731 spoofing, with prerecorded calls offering to erase credit card or loan debt in exchange for upfront fees
- Government and business imposter scams — Callers pose as government agencies or well-known companies to extract personal or financial information
- Medical and prescription fraud — Calls offering discount medications or fake insurance enrollment, targeting seniors in particular
- Home improvement and utility scams — Unsolicited offers for repairs, solar panels, or energy assistance that request upfront payment for services never delivered
Staying protected: No legitimate government agency or healthcare provider demands immediate payment over the phone. Report suspected 731 scam calls to the FTC at reportfraud.ftc.gov and to the Tennessee Attorney General's Office.

Does 731 have an overlay?
No. Area code 731 has never required an overlay since its creation in 2001. It remains the sole area code for its entire West Tennessee territory, though ten-digit dialing is still mandatory nationwide.
When was the 731 area code created?
Area code 731 was created on February 12, 2001, as a geographic split from area code 901. Tennessee's original 901 code was assigned to the entire western third of the state, including Memphis, in 1947. Rapid wireless growth in Shelby County prompted the split, with 901 retained for Memphis and 731 assigned to the surrounding rural counties.
What time zone is the 731 area code in?
Area code 731 is in the Central Time Zone. All counties in the 731 territory observe Central Standard Time (UTC−6) in winter and Central Daylight Time (UTC−5) during daylight saving time, the same zone as Memphis, Nashville, and St. Louis.
Can I get a 731 number for a business outside Tennessee?
Yes. Virtual phone providers and UCaaS platforms offer 731 area code numbers to businesses and individuals regardless of physical location. A virtual 731 number establishes authentic West Tennessee presence, routes all calls to any device anywhere in the world, and connects your business with the region's manufacturing, healthcare, and agricultural markets without a physical Tennessee office.
Is the 731 area code associated with scam calls?
Area code 731 is a legitimate telephone prefix for West Tennessee, but Tennessee ranks second in the nation for robocall complaints per capita, and 731 numbers are frequently spoofed for nationwide scam campaigns rather than purely local targeting.
The most heavily reported fraud types include debt reduction robocalls, government and business imposter scams, medical and prescription fraud, and home improvement scams. Any unsolicited call demanding upfront payment or personal information is a scam regardless of caller ID.
Why is 731 used so often in nationwide robocall campaigns?
Research shows the 731 area code has one of the lowest in-state targeting rates among Tennessee area codes, meaning scam operations frequently use spoofed 731 numbers to reach targets across the entire country rather than West Tennessee residents specifically. This makes an unexpected call from a 731 number no more likely to be local than one from any other area code.
