FIM or Facing Identification Mark patterns are another type of postal bar code used in automated mail processing by the U.S. Postal Service. FIM patterns are used for automatic facing and canceling of mail that does not contain a stamp or meter imprint (business reply mail, penalty mail, etc.). They also provide a means of separating business and courtesy reply mail from other letters. Three FIM patterns are currently in use. FIM-A is used on courtesy reply mail that has been preprinted with PostNET bar codes. FIM-B is used on business reply, penalty and franked (government) mail that is not preprinted with PostNET bar codes. FIM-C is used on business reply, penalty and franked mail that has been preprinted with PostNET bar codes. FIM patterns are placed in the upper right corner along the top edge and two inches in from the right edge of letters and cards.
