Frequently asked questions
Common questions about Shopify barcode validation.
What barcode lengths are supported?
The checker flags barcode lengths outside common EAN-8, UPC-A, EAN-13, and ITF-14 lengths: 8, 12, 13, and 14 digits.
Does it validate check digits?
The first version focuses on numeric format and length. Check digit validation can be added later if barcode cleanup becomes a major workflow.
Are blank barcodes errors?
No. Blank barcodes are allowed because many Shopify catalogs do not use barcodes for every variant.
Can it fix barcode values?
It can auto-fix safe formatting cases. Ambiguous barcode problems are left as manual fixes.
