Area code 870, Telephone prefix in Arkansas, US
Area code 870 is a telephone prefix in Arkansas covering the eastern, southern and northern parts of the state, including cities such as Jonesboro, Pine Bluff and West Memphis. The territory reaches from the Delta plains in the east to the forested hills in the north and includes long stretches along the Arkansas River.
The prefix was created in 1997 by splitting the former area code 501 due to a shortage of available telephone numbers in the state. Since January 2024, ten-digit dialing has been required throughout the region as the new overlay code 327 was added.
The region connected by area code 870 includes agricultural communities, urban centers, and rural landscapes along the Arkansas River and Ouachita National Forest.
When dialing within the code area, the full ten-digit number must be entered since January 2024, even for local calls. The change occurred because of the introduction of the additional code 327, which covers the same geographic territory.
The geographic territory of area code 870 contains multiple counties including Craighead, Crittenden, and Mississippi, serving a population mix from cities to farmland.
