How to choose the right barcode type

A practical decision guide: retail GTINs, warehouse SKUs, cartons, pharma, books, and tiny industrial marks.

Match symbology to the ecosystem

Retail POS → EAN-13 or UPC-A. Internal warehouse SKUs → Code 128. Outer cartons → ITF-14. Tiny electronics → Data Matrix. Consumer URLs → QR Code. High-speed lines → DotCode.

Confirm scanner and partner requirements

Legacy partners may still require Code 39. GS1 trading partners care about allocated GTINs more than the generator brand. Pick the format your scanners and contracts already support, then standardize templates.
