We report the result of a search for the rare decay B0\u2192\u3b3\u3b3 in 426\u2009\u2009fb-1 of data, corresponding to 226 710^6 B0B\u305 0 pairs, collected on the \u3a5(4S) resonance at the PEP-II asymmetric-energy e+e- collider using the BABAR detector. We use a maximum likelihood fit to extract the signal yield and observe 21-12+13 signal events with a statistical significance of 1.8\u3c3. This corresponds to a branching fraction B(B0\u2192\u3b3\u3b3)=(1.7\ub11.1(stat.)\ub10.2(syst.)) 710-7. Based on this result, we set a 90% confidence level upper limit of B(B0\u2192\u3b3\u3b3)<3.2 710-7
