Geo::GeoNames provides a perl interface to the webservices found at [1]. That is, given a given placename or postalcode, the module will look it up and return more information (longitude, lattitude, etc) for the given placename or postalcode. Wikipedia lookups are also supported. If more than one match is found, a list of locations will be returned.
