  Using the known numbers and evolution of unobscured AGN, and assuming that
there is a large number of corresponding obscured AGN -- as expected if AGN
unification is correct -- we predict the infrared number counts of AGN. These
agree well with the observed GOODS Spitzer data at 3.6, 8 and 24 $\mu$m,
provided that the dust content of the obscuring torus is $\sim 2$x less than
assumed. This strongly supports the AGN unification picture, and implies a
large population of infrared bright obscured AGN at all redshifts and
luminosities.
