(870 & 327 overlay; see the next row for information about changes in Arkansas for 2027)
future expansion of overlay area code (327)   In 2027 the entire state of Arkansas will merge into a single “boundary elimination” overlay of area codes 501 & 479 & 870 & 327. Area code 501 already had 10D local calls, and 870 & 327 changed over with the first overlay; area code 479 will keep 7D until the boundary elimination overlay. Exact implementation details are still to be determined. ; (Early reports suggested that the boundary elimination was planned for 2025, but the plans were clarified: network preparation will begin in 2025, but the actual boundary elimination will take place in 2027.)
