  "abstract": "The distances of Fast Radio Burst (FRB) sources are currently unknown. We show that the 21-cm absorption line of hydrogen can be used to infer the redshifts of FRB sources, and determine whether they are Galactic or extragalactic. We calculate a probability of $\\sim 10\\%$ for detecting a 21-cm equivalent width $\\gtrsim 4 ~\\mathrm{km}~\\mathrm{s}^{-1}$. The forthcoming SKA observatory provides ideal prospects for detecting our predicted signal.",
