"car rt sort" on a mailing label means that the mailer has presorted the mail
not just by zip code but right down to the carrier's route ("car rt"), and
gets special low rates for so doing.  (Obviously, this only applies to large
quantities of bulk mail going to a concentrated area -- e.g. your annual IRS
forms package.)  Many commercial mailing lists are now available with
this information in them.
