No towns meet the strict definition of “Arkansas – Missouri Bordering Towns”
Note that no incorporated towns or cities actually straddle the Arkansas–Missouri state line. Do not expect a list of single municipalities that sit in both Arkansas and Missouri at once. Under that strict definition, the search returns no entries.
Understand why this happens. State borders are legal lines set by history, rivers, and surveys. Local governments are incorporated inside one state or the other. Federal and state place databases (for example, USGS GNIS and the U.S. Census) record each town in a single state. That makes “one town in both Arkansas and Missouri” a category that rarely exists and, in this case, does not exist.
Consider close alternatives and near matches. Find towns that lie very close to the state line but remain wholly in one state. Look for unincorporated communities that sit near county lines or river crossings. Also look at examples from other state pairs to see the difference: Texarkana (Arkansas–Texas) and Kansas City (Missouri–Kansas) are well-known cities that do straddle state lines. For Arkansas–Missouri, the practical options are (1) lists of Arkansas towns that border or lie near the Missouri line, (2) lists of Missouri towns that border or lie near the Arkansas line, or (3) paired nearby towns on opposite sides of the border.
Explore those alternatives instead: create a county-by-county list of communities along the Arkansas–Missouri boundary, map towns within a set distance of the line, or compile paired towns on each side of the border using authoritative sources (USGS GNIS, U.S. Census, and state DOT/county GIS).
