We search for direct CP violation in flavor specific B→Kπ decays by measuring the rate asymmetry between charge conjugate modes.The search is performed on a data sample of 11.1× 106 BB̄ events recorded on the Υ(4S) resonance by the Belle experiment at KEKB. We measure 90% confidence intervals in the partial rate asymmetry ACP of -0.25<ACP(K± π±)CP(K± π0)CP(K± + π0)± π± and K± π0 final states, we conclude that -0.22 CP(K±±: + π0))
