The GeV $\\gamma$-ray emission is extended and spatially coincident with molecular clouds traced by CO emission. The broadband GeV to TeV emission of VER J2227+608 can be well fitted by a single power-law function with an index of 1.90$\\pm$0.04, without obvious indication of spectral cutoff toward high energies. The pure leptonic model for the $\\gamma$-ray emission can be marginally ruled out by the X-ray and TeV data.
