# Barcode Generation Issues

### Problem
You generated barcodes, but some products still do not have a barcode or the generated barcodes are not what you expected.

###### Check 1 — Check the products
Go to:
**Generate & Print → Choose Products**
Select the products or variants that need a barcode.
Make sure you selected the correct products before generating.

| **Note:** Some generation options can create new barcode values for existing products. Check the option carefully before clicking **Generate**.

###### Check 3 — Check the barcode format
Go to:
**Settings → Barcode**
Check the **Barcode Format** or related barcode generation settings.
Make sure the selected format is supported by your workflow and scanner.

###### Check 4 — Generate again
After checking the settings:
1. Return to **Generate & Print**.
2. Select a small number of products.
3. Generate the barcodes.
4. Check the generated values in Shopify.

### Result
The selected products should have the expected barcode values.

| **Tip:** Test with 1–2 products before generating barcodes for your entire store.
