SKU Generation Issues
Problem
The generated SKU is incorrect, missing, duplicated, or does not follow the format you expected.
Check 1 — Check SKU settings
Go to:
Settings → SKU
Review your SKU generation settings, including:
- Prefix
- Suffix
- Data abbreviation
- Variant-related options

Check 2 — Check the product information
Go to Generate & Print and select the affected product.
Make sure the product and variant information required by your SKU structure is available.

Check 3 — Check existing SKUs
Open the product in Shopify Admin → Products.
Check whether the product or variant already has a SKU.
Check 4 — Test with one product
Generate a SKU for one product first.
Check whether the result follows your expected structure.
Result
If the test SKU is correct, you can continue with the remaining products.
