Barcode

Self-assigned EAN-13 / UPC-A numbers scan fine for internal stock control, but they are not valid for retail resale. That needs a licensed GS1 company prefix. Prefixes starting 02 or 20–29 are reserved for in-store use, which is why 200 is the default here.

Safety checks

Keep every SKU unique

Resolves collisions against existing SKUs too

Avoid lookalike characters

Keeps 0/O and 1/I/L out of {RAND} codes

Don't start with a digit

Spreadsheets silently drop leading zeros

Replace existing barcodes

Off: rows that already have a barcode keep it. Leave this off unless you mean to overwrite real GS1 numbers.

8–16 characters reads best on a shelf; 20 leaves room for a four-digit sequence. Shopify publishes no hard SKU limit. Amazon caps seller SKUs at 40. Set 0 to switch the check off.

Abbreviation library

One value=CODE per line. Used by the :abbr transform so everyone on the team shortens attributes identically.

Unrelated, but since you’re here

Appbrew builds mobile apps for Shopify brands. Nothing to do with SKUs or barcodes. This tool is free either way, no signup, no catch. If a mobile app happens to be on your roadmap, take a look. If not, enjoy the generator.
