The UCC Serial Shipping Container Code specification calls for a 19 digit UCC/EAN 128 code with an
additional Mod 10 Check digit (20 digits in all). The Mod 10 Check digit is calculated the same as the
Interleaved 2 of 5 example in Appendix D. It is the data length as well as the MOD 10 check digit that
distinguishes the UCC Serial Shipping Container Code from other UCC /EAN 128 bar codes.
Scanning the appropriate bar codes on the RF Terminal Setup Menu enables UCC/EAN 128; or you can use
the keypad in the PROGRAMMING MODE “Change Setup” option. If UCC/EAN 128 is enabled, you will
be able to read both standard Code 128 bar codes as well as the UCC/EAN 128 bar codes with the Function
1 character and the Mod 10 check character.
UCC-128 Shipping Container Code
If UCC/EAN-128 is enabled on the R/F Terminal reader, all Function 1 codes are transmitted as ]C1. In
addition, should you be reading a 20 digit Shipping Serial Container code, the Mod 10 check digit is also
compared with the computed Mod 10 value to give further assurance of no substitutions. The UCC/EAN-
128 Shipping Serial Container Code is a subset of UCC-128 or EAN-128 adopted for voluntary marking of
shipping boxes with the exact serial number of the box, (used with EDI typically to identify a specific boxes
contents. The code consists of the following format:
Start C not transmitted
Function Code 1 transmitted
2 Digit Qualifier transmitted
7 Digit Data Portion transmitted
1 Digit Mod 10 Check Digit* transmitted-
1 Digit Modulus 103 not transmitted
Stop Code not transmitted
*Calculated using 19digits-UPC method
The UCC 128 specification is used extensively by the retail industry. If you have a requirement for a UCC
128 Serial Shipping Container bar code, be sure to follow the specification as closely as possible as many
