870 Area Code: Jonesboro & Pine Bluff, AR — Full Guide

Introduction

The 870 area code covers most of Arkansas outside the Little Rock and Northwest Arkansas metro areas, spanning the Delta, the Ozarks, and the state's southern border. Knowing the 870 area code matters whether you are checking an unknown call from Jonesboro, doing business across the Delta farming region, or trying to look local to hundreds of thousands of Arkansans outside the capital. This guide walks through the code's history, its major cities, Central Time calling windows, how to spot scam calls, and how to claim a local number in minutes. By the end, you will see why a trusted Arkansas prefix still beats any national or toll-free line.

What Is the 870 Area Code?

The 870 area code is a North American Numbering Plan (NANP) code that covers the largest geographic footprint of any Arkansas area code. It wraps around the Little Rock metro on nearly every side, reaching from the Mississippi River Delta in the east to the Ozark and Ouachita mountain regions in the north and south. Rather than a single metro identity, 870 represents dozens of small and mid-size cities spread across a mostly rural state.

What Geographic Area Does 870 Cover?

Area code 870 covers everywhere in Arkansas except the Little Rock metro (501) and the Fort Smith and Fayetteville-Springdale-Rogers region of Northwest Arkansas (479). That includes Crowley's Ridge and the Delta around Jonesboro and West Memphis, the Pine Bluff and Delta cotton and rice belt to the south, the Ozark foothills near Mountain Home, and the Texarkana and El Dorado communities along the southern border.

870 Area Code History: The 501 Split

Arkansas's numbering story starts with 501, assigned to the entire state in 1947 under the original North American Numbering Plan. For decades, one code was enough. By the mid-1990s, however, population growth and the rise of mobile phones and fax lines were draining the 501 pool statewide, and regulators needed a way to add capacity without disrupting the fast-growing Little Rock capital region.

The 1997 Split and the 2024 Overlay

On April 14, 1997, the state's outer regions split away from 501 to form the 870 area code, becoming Arkansas's second area code and leaving 501 to serve only the Little Rock metro. Northwest Arkansas followed in 2002 with its own split, 479. By the early 2020s, growth around Jonesboro and the Delta pushed 870 toward exhaustion again, and in 2024 the state added 327 as an overlay — similar to how 847 area code gained the 224 overlay in Chicago's suburbs. Existing 870 numbers did not change; residents simply began dialing all ten digits.

Cities and Communities in the 870 Zone

The 870 code spans a wide range of Delta farming towns, riverfront cities, and Ozark foothill communities. Here are the places that define the region.

Jonesboro and Crowley's Ridge

Jonesboro is the largest city in the 870 zone and the commercial hub of northeastern Arkansas, home to Arkansas State University and a growing healthcare and retail sector. Paragould, just north, serves as a secondary manufacturing and distribution center along Crowley's Ridge, a distinctive forested highland rising above the flat Delta farmland.

Pine Bluff and West Memphis

Pine Bluff anchors the Delta region south of Little Rock, historically tied to cotton and now home to a diversifying industrial base along the Arkansas River. West Memphis, directly across the Mississippi River from Memphis, Tennessee, serves as a major trucking and logistics hub thanks to its position at the intersection of two interstate highways.

Texarkana, El Dorado, and Mountain Home

Texarkana straddles the Arkansas-Texas border and shares its name and identity across both states, anchoring the southwestern corner of the 870 zone. El Dorado, once a booming oil town, remains a regional center for energy and manufacturing in south Arkansas. Mountain Home, in the Ozark foothills near the Missouri border, serves as a retirement and outdoor-recreation hub around Norfork and Bull Shoals lakes.

Time Zone and Calling Hours

The 870 region sits entirely in the Central Time Zone, the same clock as the rest of Arkansas. Standard time (CST) runs UTC−6 from the first Sunday in November through the second Sunday in March. Daylight saving time (CDT) runs UTC−5 from the second Sunday in March through the first Sunday in November. If you are calling from another zone, plan around a standard Central business day.

Why Businesses Choose an 870 Number

Most of Arkansas outside the capital answers to a local rather than a big-city identity, and a familiar 870 prefix signals that your business understands the region. Much like Mississippi's 601 area code does for Jackson, that local trust shows up directly in answer rates and callback conversions across rural and small-city Arkansas.

• Energy and manufacturing — El Dorado's oil and chemical sector depends on local numbers for vendor and contractor relationships
• Remote routing — forward an 870 number to any device anywhere and keep a genuine Arkansas presence with no office required

870 Scam Calls: How to Stay Protected

The 870 area code is a fully legitimate Arkansas code used every day by hundreds of thousands of residents, businesses, hospitals, and schools across the state. Like every NANP code, it can be spoofed — a scammer can display an 870 number with no real link to Arkansas. For official guidance on spoofed caller ID and your rights under federal law, see the FCC spoofing guide.

Common 870 Scam Patterns

Neighbor spoofing is the most common tactic — scammers show a local-looking 870 number to boost answer rates. IRS and Social Security impersonation scripts are widespread, auto-warranty robocalls stay relentless, and farm equipment or crop insurance scams target the Delta agricultural belt during planting and harvest season. Treat any unsolicited demand for fast payment as a warning sign.

How to Protect Yourself

• Never share bank account numbers, Social Security details, or one-time codes with an unsolicited 870 caller
• Government agencies and utilities never demand payment by gift card or wire — hang up if a caller insists
• Use a reverse-lookup service before returning any unfamiliar 870 number
• Register on the National Do Not Call Registry at donotcall.gov to cut down on telemarketing
