The Serial Shipping Container Code (SSCC) is an 18-digit number used to identify logistics units. In order to automate the reading process, the SSCC is often encoded in a barcode, generally GS1-128, and can also be encoded in an RFID tag. It is used in electronic commerce transactions.
The GS1 Identification Key is used to identify physical locations or legal entities. The key comprises a GS1 Company Prefix, Location Reference, and Check Digit. Location identified with GLN could be a physical location such as a warehouse or a legal entity such as a company or customer or a function that takes place within a legal entity.
For instance, the UPC-A barcode for a box of tissues is "036000241457". The last digit is the check digit "7", and if the other numbers are correct then the check digit calculation must produce 7. Add the odd number digits: 0+6+0+2+1+5 = 14. Multiply the result by 3: 14 × 3 = 42. Add the even number digits: 3+0+0+4+4 = 11.
The weight at a specific position in the EAN code is alternating (3 or 1) in a way, that the final data digit has a weight of 3 (and thus the check digit has a weight of 1). All Global Trade Item Number (GTIN) and Serial Shipping Container Code (SSCC) codes meet the next rule:
A GS1-128 barcode encoding GTIN, best before date and batch number. GS1-128 (formerly known as UCC/EAN-128) is a subset of Code 128 and is used extensively worldwide in shipping and packaging industries as a product identification code for the container and pallet levels in the supply chain.
The Global Trade Item Number (GTIN) is an identifier for trade items, developed by the international organization GS1. [1] Such identifiers are used to look up product information in a database (often by entering the number through a barcode scanner pointed at an actual product) which may belong to a retailer, manufacturer, collector, researcher, or other entity.
A mapping of GS1 identifiers to URNs to be used in EPCIS (see EPCIS 1.2 section 6.4 Identifier representation). The latest TDS version defines the following GS1 Identification Keys: Global Trade Item Number (GTIN), including RCN-8, GTIN-8, GTIN-12, GTIN-13, ISBN, ISMN, ISSN for a class of products, goods or services; GTIN + Batch/Lot (LGTIN)
GS1 is a not-for-profit, international organization developing and maintaining its own standards for barcodes and the corresponding issue company prefixes. The best known of these standards is the barcode, a symbol printed on products that can be scanned electronically. GS1 has 118 local member organizations and over 2 million user companies.
