  We report on a search for eleven lepton-number violating processes B+ -> X-
l+ l'+ with X- = K-, pi-, rho-, K*- or D- and l+/l'+ = e+ or mu+, using a
sample of 471+/-3 million BBbar events collected with the BaBar detector at the
PEP-II e+e- collider at the SLAC National Accelerator Laboratory. We find no
evidence for any of these modes and place 90% confidence level upper limits on
their branching fractions in the range $(1.5-26)\times 10^{-7}$.
