We obtain the current constraint on the minimally extended varying speed of light (meVSL) model by analyzing cosmic distance duality relation (CCDDR) of it, DL/DA(1+z)-2 = (1+z)b/8. We use the Pantheon type Ia supernova (SNIa) data, the Hubble parameter H(z) using the cosmic chronometers approach, and the cosmic microwave background (CMB) distance priors from the latest Planck data. We find that the current data show the 1-σ deviation from the standard CCDDR. Thus, this provides the constraint on meVSL model and future precision observations might be able to put stronger constraints on it.
