Area Code Breakdown & Regional Mapping
731 – West Tennessee Code
Area code 731 was created in 2001 when it split from 901, serving rural West Tennessee including Jackson, Dyersburg, and Union City. It covers Jackson and Madison County as a single, non-overlaid area code.
Neighborhoods & Local Coverage
Jackson’s 731 code covers a city anchored by a historic Downtown around the Madison County Courthouse and the revitalized district near the AMP amphitheater. The Casey Jones Village, honoring the legendary railroad engineer, and the campuses of Union University and Jackson State draw visitors and students to the city.
Beyond downtown, the same code reaches the North Jackson commercial corridor along the interstate, the residential neighborhoods around the medical district, and the surrounding Madison County countryside. As the hub of rural West Tennessee, the 731 code ties Jackson to the smaller towns across the region.
Local Dialing Rules, Time Zone & International Format
Because 731 is a single area code with no overlay, Jackson still permits 7-digit dialing for local calls, though 10-digit dialing (area code + number) always works. Memphis to the southwest uses 901.
A note on Tennessee time: Jackson sits in the Central Time Zone, like the rest of West Tennessee. Only the eastern third of the state — Knoxville, Chattanooga, and the Tri-Cities — is on Eastern Time, an hour ahead.
To call Jackson from outside the United States, dial your country’s exit code, then the U.S. country code +1, followed by the 10-digit number (for example, +1 731 XXX-XXXX). From inside the U.S. and Canada, simply dial 1 before the 10-digit number for long-distance calls.
Major ZIP Codes Covered
The 731 service area spans many of Jackson’s core ZIP codes, including 38301, 38305, and 38308.
Spam & Scam Call Warnings in Jackson
Jackson residents report spoofed 731 robocalls impersonating utilities like JEA (Jackson Energy Authority), the IRS, and delivery services. Fake-warranty and Medicare robocalls also target the area’s older population.
| Scam Type | What to Watch For |
|---|---|
| Neighbor Spoofing | Calls that mimic a local 731 prefix to look familiar. |
| Utility / Toll Scams | Threats to shut off power or demand toll payment via gift cards. |
| IRS / Government | Robocalls claiming legal action — agencies never call to demand instant payment. |
Red flag: Any caller who pressures you to pay immediately with gift cards, wire transfers, or cryptocurrency is almost certainly running a scam. Hang up and verify through an official number.
