The same calculation from GTIN (EAN/UCC) format is used to GLN, SSCC, GSRN, GSIN and GCN .

Is possible to create one module for all formats. What you think?

Hi @thiagola92,

The GTIN codes are already supported in the stdnum.ean module. Recently a stdnum.gs1_128 module was also added that can be used to validate and build GS1-128 barcode values.

I think that mostly leaves GSIN and SSCC which are currently not yet implemented.

I belive this can be close, because GSIN and SSCC are mentioned in:
