When implementing Scan4Transport, user organisations use the GS1 2D barcodes (GS1 DataMatrix and GS1 QR code). Data elements encoded within these barcodes must comply with the current rules for GS1 barcodes.

To ensure global use of Scan4Transport, Non-Latin characters and a space character may be included in the barcode using the percent encoding approach described in section 10. These “special characters” are characters that are not included in the character set allowed for the specific type of barcode.

A Scan4Transport label SHALL include a GS1-128 barcode encoding the SSCC along with the two-dimensional barcode containing Scan4Transport data elements.

When creating a Scan4Transport compliant transport label an SSCC (00) is the required identifier.

If the 2D barcode is intended to support ship-to address information, the following data elements are recommended as a minimum:

■ SSCC (00)

■ Ship-to / Deliver-to address line 1 (4302)

■ Ship-to / Deliver-to postal code within a single postal authority (420)

The GS1 Company Prefix is included at the beginning of the GS1 identification keys and so establishes global uniqueness (see section 9 for more information).

■ The GS1 Company Prefix SHALL only be used to issue keys by or on behalf of the company that is the licensee of the GS1 Company Prefix, in accordance with the key allocation rules specified in GENSPECS section 4 Application rules and management practices.

An individual Global Identification Number for Consignment is a unique number, which remains the same for the life of a grouping of logistics or transport units to which it is assigned. When assigning a GINC, the rule is that an individual GINC number must not be reallocated within one year of the shipment date from the freight forwarder assigning the GINC to a transport. However, prevailing regulatory or industry organisation specific requirements may extend this period.
