Why barcodes matter
Scanning replaces typing and guessing everywhere goods move: receiving, picking, packing, counting, checkout. The same GTIN also identifies products to marketplaces and shopping feeds, matching your listing to the catalog entry.

Questions
Where do product barcodes come from?
Retail GTINs are licensed through GS1, the standards body, so codes are globally unique; marketplaces increasingly verify against the GS1 registry. Internal-only barcodes for bins and SKUs, you print yourself.
Does every product need a GTIN?
Selling on marketplaces and shopping feeds, usually yes, with exemption processes for handmade and private label cases. Your own store alone, internal SKUs suffice.
