Barcode Elements<br />
This section describes the individual data elements that comprise the various<br />
barcodes that may be used for Delivery <strong>Confirmation</strong> and Signature<br />
<strong>Confirmation</strong> services and all integrated barcode solutions. If UCC/EAN Code<br />
128 barcode symbology is used, a two-character Application Identifier (AI) is<br />
also required. A UCC/EAN Code 128 barcode contains a variable length<br />
sequential package ID. All other symbologies have a fixed length of 20<br />
characters. See Table G-1 for data elements.<br />

Data<br />
Application Identifier (UCC/EAN Code 128 only)<br />
Service Type Code — 2 digits<br />
Customer ID — 9-digit D-U-N-S Number<br />
Sequential Package ID — 8 digits<br />
(This field may vary in length up to 8 digits if the<br />
UCC/EAN Code 128 barcode symbology is used.)<br />
Check Digit — MOD 10<br />

Start Code<br />
Function One<br />
(UCC/EAN Code 128 only)<br />
MOD 103 (Code 128 only)<br />
Stop Code<br />
Start Code<br />
All barcodes must have a Start Code. USS Code 128 and UCC/EAN Code<br />
128 begin with a Start Code C. The start character is not shown in the<br />
human-readable presentation, nor is it manually keyed or transmitted.<br />
Function One<br />
The Function One (FNC1) numeric character for UCC/EAN Code 128 must<br />
follow the symbol start character and is part of the symbology overhead. The<br />
FNC1 is also used to concatenate successive UCC/EAN Code 128 barcode<br />
symbols and must precede an AI. The FNC1 character is not part of the<br />
human-readable character set, nor is it manually keyed or transmitted as<br />
data.<br />
Application Identifier<br />
This is a two-digit code within UCC/EAN Code 128 only for the Package<br />
Identification Code (PIC) and the electronic file number.<br />
The AI for confirmation services is <strong>91</strong> and must be shown as part of the<br />
human-readable printed data for the tracking barcode. If concatenation is<br />
used to include the package routing code (destination ZIP Code), then the AI<br />
of 420 must also be shown as part of the human-readable print for the routing<br />
