The serial shipping container code (SSCC) is an 20-digit number used to identify logistics units. The SSCC is encoded in a barcode, generally GS1-128, and used in electronic commerce transactions.
The SSCC comprises an extension digit, a GS1 company prefix, a serial reference, and a check digit.
The SSCC is commonly used in the advance ship notice (ASN) EDI transaction.

The UCC / EAN-128 symbology and the associated Application Identifiers (AIs) are used to represent the SSCC, and any additional data required, in machine-readable form. UCC/EAN-128 is reserved exclusively for the encoding of data elements prefaced with an UCC/EAN Application Identifier. The AI that identifies the following data as an SSCC is 0 0.

Key to Table:
- ST - SSCC-18/128 Start Code (consisting of Start - C plus Function Code 1)
- AI - SSCC-18/128 Serial Shipping Container Application Identifier
- CT - Shipping Container Type
- MI - UCC/EAN Manufacturer ID Number including Number System Character proceeded by zero
- SN - Shipping Container Serial Number
- CD - Modulus 10 Check Character
- C1 - Modulus 103 Check Character (symbol character)
- SP - Stop Character
Note: The SSCC-18/128 Serial Shipping Container Code is a numeric-only application standard. Only numeric data (other than start, modulus 103 check digit, and Stop characters) are to be encoded in the symbol.
Barcode Segment Definitions
Start Code-C / Function Code 1 (ST)
This is the start code for the SSCC-18/128 Serial Shipping Container Code. It is comprised to two discreet non-data characters (Start Code-C immediately followed by Function Code 1). Typically, the proper start code for the SSCC-18/128 is automatically inserted by the label generation equipment, which properly supports the UCC symbology upon selection of UCC/EAN-128 or SSCC-18/128 with only numeric data to be encoded.
Application Identifier (A1)
The application identifier is a prefix used to define data fields. Each prefix uniquely identifies the meaning and the format of the data field following it. The application identifier assigned for the SSCC-18/128 Serial Shipping Container Code is 00. The human readable interpretation of the application identifier should be separated from the remainder of the symbol data by the use of parenthesis. The parentheses are not included in the encoded data.
Shipping Container Type (CT)
The one digit field identifies the type of serialized shipping container packaging. The following container type values are valid for the Consolidated Pick & Pack program: 0 Serial number shipping case or carton identification 1 Serial pallet (larger than case/carton).
Manufacturer ID Number (MI)
This seven-digit field contains the manufacturer's ID number assigned by the applicable UCC/EAN authority. The six-digit UPC manufacturer number is preceded by a zero to complete the seven-digit field.
Shipping Container Serial Number (SN)
The shipping container identifier is defined as a nine-digit serial number with a possible value from 000000000 to 999999999. The purpose of the serial number is to uniquely identify each shipping container (carton or pallet) packed by a supplier for a minimum of one year. The unique serial number approach allows for automatic referencing, by shipping container. Shipping containers will be uniquely identified by the 17-digit combination of a shipping container type, manufacturer ID number and a serial shipping container identification number.
The method for assigning the serial number is up to the supplier's discretion. However, the serial number must remain unique for a period of at minimum one-year for each Shipping Container Type and Manufacturing ID number.
Serialized container identification is specifically designed for use with the retail Electronic Data Interchange (EDI) systems. An EDI standard has been developed specifically for the Advanced Shipment Notification (ANSI ASC X12 Transaction Set 856).
Check Digits (CD & CI)
The SSCC-18/128 Serial Shipping Container Code utilizes two check digits the modulus 10 and the modulus 103. The two-digit numeric application identifier is not included in the modulus 10 calculation, only the remainder of the numeric data portion of the symbol is used to calculate the modulus 10 check digit. This check character, which is calculated and printed in human readable form, is to increase data integrity when manual (i.e. keyboard) data entry is used. The modulus 10 check character must be calculated prior to the modulus 103 check character as the resultant modulus 10 character is used during the calculation of the modulus 103 check character.
Stop Character (SP)
This non-data symbol character tells the scanner that it has reached the end of this SSCC-18/128 symbol.
