Abstract: The observed matter-antimatter asymmetry in the universe is a serious challenge to our understanding of nature. Baryon/lepton number violation (BNV/LNV) decays have been searched for in many experiments to understand this large-scale observed fact. We present the recent results from the BESIII experiment, including a search for BNV through $\Lambda-\bar{\Lambda}$ oscillation in the decays $J/\psi\to pK^-\bar{\Lambda}$ and $J/\psi\to\Lambda\bar{\Lambda}$. We also present searches for LNV in $D_s^+\to h^+h^0e^+e^-$ and $\omega/\phi\to\pi^+\pi^-e^+e^-$ decays, alongside probes into processes violating both baryon and lepton numbers simultaneously, such as $\Xi^0\to K^+e^-/K^-e^+$.
