Auto EAN Generator helps store owners automatically generate valid EAN-13 barcodes for products that are missing both EAN and UPC values. This is especially useful for stores with large catalogs imported from other systems or vendors, where barcode data is often incomplete or missing entirely.

You can bulk-generate EAN codes in one click. The module ensures each generated barcode follows the EAN-13 standard, producing a clean 12-digit base number and computing a valid check digit for accuracy.

The tool only targets products with both EAN and UPC fields empty, so it never overwrites existing data. You can safely re-run the process as your catalog grows or new products are added.

EANs are stored in the native ean field in OpenCart's product table, so there is no need to modify your database structure. This module works well alongside tools like Admin Product Barcode Viewer.

This is fully compatible with OpenCart 3.x.
