description: Based on 7.33 fb$^{-1}$ of $e^+e^-$ collision data taken at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we measure the branching fraction of $D^{*+}_s\to D^+_sπ^0$ relative to that of $D^{*+}_s\to D^+_sγ$ to be $(6.16\pm 0.43\pm 0.19)\%$. The first uncertainty is statistical and the second one is systematic. By using the world average value of the branching fraction of $D^{*+}_s\to D^+_se^+e^-$, we determine the branching fractions of $D^{*+}_s\to D^+_sγ$ and $D^{*+}_s\to D^+_sπ^0$ to be $(93.57\pm0.44\pm0.19)\%$ and $(5.76\pm0.44\pm0.19)\%$, respectively.
