Service Type Identifiers (STIDs)

The Intelligent Mail barcode (IMb) 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 (non-automation) 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.

Who is STID for?

Mailers using the Intelligent Mail barcodes for letters and flats, both basic (non-automation) and Full-Service.

First Class Mail
Periodicals
Standard Mail

Description

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

Mailers that include a Basic Nonautomation STID requesting electronic address corrections (ACS) must complete the ACS™ Enrollment Form to set up an account for fulfillment and billing of OneCode ACS or a SingleSource account for both Full-Service and OneCode ACS notices.

IMb Tracing customers interested in receiving the mail piece tracking data must contact the IMb Tracing Help Desk to register any new MIDs or add/change any new STIDs in their subscription.

With this information, mailers can reference Appendix A, which has comprehensive information to determine the appropriate STID to use for ancillary services preferred.
