We have searched the WISE mid-IR catalog to identify counterparts of yet unassociated bright Fermi-LAT g-ray sources located in the Galactic plane. These GeV sources could have a galactic origin, most likely, orthey could be extragalactic objects such as blazars, or even a new type of g-ray emitter. The key to understand these objects and determine their physical nature is the identification of their counterparts at other wavelengths. Due to the deficit of blazars discovered so far in the Galactic plane, it is expected that many of the unassociated Fermi sources are blazar. We have searched into these g-ray unidentified sources looking for non-thermal emission in the IR. We have found only 1 out of 10 g-ray Fermi sources to have a WISE blazar candidate within their position error regions.
