We have searched and reviewed all multi-wavelength data available for the region towards the gamma-ray source 2FGL J2056. 7+4939 in order to constrain its possible counterpart at lower energies. As a result, only a point-like optical/infrared source with flat-spectrum radio emission is found to be consistent with all X-ray and gamma-ray error circles. Its structure is marginally resolved at radio wavelengths at the sub-arcsecond level. An extragalactic scenario appears to be the most likely interpretation for this object. © 2012 Springer Science+Business Media B.V.
