The audit is EasyLink's starting point: it checks every variant in your catalog and tells you exactly which barcodes are ready to become scannable codes.
Run an audit
Open EasyLink → GTIN audit.
Click Run audit (or Re-run audit).
EasyLink reads your whole catalog in the background — the page updates itself as it works. Large catalogs take a minute or two.
Reading the results
The Catalog health tiles show every variant classified into:
Status | Meaning |
|---|---|
Valid | A properly formed GTIN (UPC/EAN/GTIN-8/14) with a correct check digit — ready to publish |
Missing | The variant has no barcode at all |
Malformed | The right length for a GTIN, but the check digit is wrong — usually a typo |
Internal | A barcode that isn't a GTIN (custom codes, SKU-style values) — fine for internal use, but can't become a GS1 code |
Duplicate | The same barcode appears on more than one variant — each sellable variant needs its own GTIN |
Click any tile to filter the variant list. Each row links to the product in Shopify admin (to fix the barcode) and — for valid variants — to its EasyLink code page.
Keeping the audit fresh
You don't need to re-run the audit every time you edit a product. When you change a variant's barcode, title, or SKU in Shopify, EasyLink updates that row automatically within moments. Re-run the full audit after large imports or bulk edits.
Export
Click Export CSV to download the complete audit — every variant with its barcode, normalized GTIN, classification, and a plain-English issue description. Handy for sharing a cleanup list with your team or supplier.
