Accurate prediction of geo-neutrinos from the crust serves as a necessary prerequisite in determination of the geo-neutrino flux from the mantle. In this work, we report the non-negligible oscillation effect in the calculation of the crustal geo-neutrinos, which is usually approximated as a constant average in the previous calculations. An underestimate of around 1-2 TNU for the geo-neutrino signal is observed because of the oscillatory behavior within the local crustal region of around 300 km. Besides, the signal correction given by the Mikheyev-Smirnov-Wolfenstein oscillation from that based on vacuum oscillation is around 0.1%-0.3% for the local crust. This work reminds that the exact oscillation possibility in matter should be considered for future prediction of the local crustal geo-neutrinos.
