You could use a spatial joint. ArcGIS Desktop

but how do i join if i don't have common id on both files.

The Spatial Join works by joining information based on location, which is different than an attribute join (an attribute join is typically based on a common ID field).  So don't worry about not having a common ID.

Quick thought - a couple of processes come to mind that would probably work:

1.  Do a "Spatial Join":

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

2.  Alternatively, run an Identity (Geoprocessing tool):

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

Be sure to mark Tim Witts' post as the correct solution.  Both so he gets credit for it (he beat me to it) and so others who search on this topic see that an answer was found.

Thanks,
