Service Type Identifier (STID) Table Effective February 23, 2019

The STID (Service Type Identifier) is a three-digit numeric code used within the Intelligent Mail® barcode (IMb™) on a mailpiece that identifies the address correction or other electronic services desired. The STID Table allows you to determine which STID to use based on the mail class, address correction option, use of IMb Tracing™ and whether the mail contains a Full Service or Basic IMb.
