We investigate perfect codes in Z(n) in the l(p) metric. Upper bounds for the packing radius r of a linear perfect code, in terms of the metric parameter p and the dimension n are derived. For p = 2 and n = 2, 3, we determine all radii for which there exist linear perfect codes. The non-existence results for codes in Z(n) presented here imply non-existence results for codes over finite alphabets Z(q), when the alphabet size is large enough, and have implications on some recent constructions of spherical codes.
