Service Type Identifier
The Intelligent Mail barcode is used to identify mailpiece movement through the postal system and support any additional services requested for that mailpiece. The STID defines the mailpiece as full-service or basic (Nonautomation) and is also used to determine the disposition of undeliverable-as-addressed (UAA) mail and the form of address correction that a mailer desires if any.
The main attributes that determine which STID to use for Intelligent Mail barcoded mail are the
address correction services selected for the mailing, the mail class, and the service option. When deciding which STID to use in IMb, mailers need to know:
- The mail class.
- The address correction service (if any) that is desired.
- The service option – Full-Service or Basic/Nonautomation*.
- For IMb Tracing subscribers, whether IMb Tracing is desired**.
- The fees, if any, that will be associated with the use of each STID and/or ancillary service request.
With this information, mailers can reference Appendix A, which has comprehensive information to determine the appropriate STID to use for ancillary services preferred.
