Facing Identification Mark

The facing identification mark (FIM) serves to orient and separate certain types of First-Class Mail during the facing-canceling process.

• FIM A is used for Courtesy Reply Mail and Meter Reply Mail, and must have a pre-printed barcode.
• FIM B is used for Business Reply Mail without a barcode.
• FIM C is used for Business Reply Mail with a barcode.
• FIM D is for IBI Meters and PC Postage systems, no barcode required
• FIM E is for mail that goes out with Customized Services and must use an Intelligent Mail barcode

The Facing Identification Mark barcode is designated by the USPS to assist in automatically processing mail. These are the vertical bars located to the left of the stamp on many preprinted envelopes.

Postal Indica

Printed indicia, instead of an adhesive postage stamp or meter stamp that shows postage prepayment by an authorized mailer. You can apply for a permit with the United States Postal Service here.

Postage indica designation on male denotes postage payment through the United States Postal Services, requiring a permit number through them.

Postal Endorsements

These lines of text will inform the United States Postal Service of additional requests in the case that the mail is undeliverable. When these services are used, there is an additional fee to the USPS, information on the fees can be found here.

Ancillary service endorsements are used by mailers to request an addressee's new address and to provide the USPS with instructions on how to handle undeliverable-as-addressed pieces. They are the same for each class of male, though there are different costs associated with the various services. (See usps.com for postage rates).
