Data Fields in the IMb – Service Type ID (STID)
{"Image DocumentName": "Data Fields in the IMb \u2013 Service Type ID (STID)", "Image ImageDescription": "A 3-digit field used to identify the class of mail and any additional or special services requested for the piece such as OneCode ACS, IMb Tracing, or no service. Defines the mailpiece as Full-Service, Basic or Non-Automation. Used to determine the disposition of Undeliverable-As-Addressed (UAA) mail and the form of address correction desired by the mailer. The second field, the Service Type Identifier (STID) is a 3-digit field. Each 3-digit value corresponds to a particular mail class with a particular combination of services where mailers will indicate the class of mail and also request special services, such as IMb Tracing or OneCode ACS. In addition, the Postal Service anticipates supporting many combinations of classes and services using this field. The Service Type Identifier defines whether the Full-Service or Basic Option has been selected for a given mailpiece. Those interested in the IMb Tracing service for Full-Service or Basic mailpieces must subscribe and register with the IMb Tracing help desk, and indicate the request for the IMb Tracing service in the Service Type ID on the mailpiece. In addition, address correction information is also available for purchase for the Basic option through the OneCode ACS program. Now, let\u2019s look at the STID chart for First-Class Mail.
