Service Type Codes<br />
To make it easier for shippers to use multiple special services, we have<br />
expanded the service combinations that can be included in a single barcode.<br />
Table B is a matrix of current active Service Type Codes (STCs) for the<br />
Delivery <strong>Confirmation</strong> service, Signature <strong>Confirmation</strong> service, and Integrated<br />
Barcode programs. STCs are designated within a barcode to identify the<br />
class of mail and/or type of special services included on the mail item.<br />
Consult Domestic Mail Manual (DMM) R900 or Notice 123, Ratefold, for the<br />
appropriate fees for each added service. Rate information is also available at<br />
the Postal Service Web site www.usps.com.<br />
<strong>Confirmation</strong> Service Type Codes<br />
The Service Type Code consists of the two characters immediately following<br />
the Application Identifier (<strong>91</strong>) in the Package Identification Code (PIC) of a<br />
barcode using the UCC/EAN Code 128 barcode symbology. If you are using<br />
one of the alternate barcode symbologies (USS Code 128, USS Code<br />
Interleaved 2 of 5, or USS Code 3 of 9), it will be the first two characters of<br />
the PIC.<br />
A Service Type Code of 50 has been reserved for use in the Electronic File<br />
Number field of the Header Record.<br />
