  We obtain the current constraint on the minimally extended varying speed of
light (meVSL) model by analyzing cosmic distance duality relation (CCDDR) of
it, $D_{L}/D_{A}(1+z)^{-2} = (1+z)^{b/8}$. 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-$\sigma$ 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.
