This add-on improves your product data by adding new fields:

As an administrator, you can choose where to display these fields: in both Admin and Customer areas, only in the Admin area, or not at all. This setting applies to both products and their variations.

Each product you sell online should have at least one of the following attributes, ideally both: Barcode (GTIN, UPC, ISBN, etc.) and Manufacturer Part Number (MPN). These identifiers make your products and ads appear more frequently in search results on platforms like Google and eBay, thereby helping people find and purchase your products more easily. Major online sales channels, like Amazon, often don’t allow product listings without them.

Barcode is a numeric code typically composed of 8, 12, 13, or 14 digits, depending on the region and use. This code should be a new or existing Global Trade Item Number (GTIN), such as UPC (12-digit, North America), EAN (8 or 13 digits, Europe), JAN (8 or 13-digit, Japan), or ISBN (13-digit, books), among others. Using GTIN ensures your products can be identified internationally.

Manufacturer Part Number (MPN) is a manufacturer-assigned code that helps improve product identification, especially when a GTIN is not available.

After identifying an item's Barcode and/or Manufacturer Part Number (MPN), you can add this information to the product's details. To do that, navigate to the Info tab on the product details page. There, you'll find the required fields:

Enter the values you require and click Update product.

Adding barcodes and MPNs for product variations works the same way as for regular products. Navigate to the Info tab on the product details page and fill the required fields.

Unlike the Product Variants add-on, the Product Variations add-on does not provide a unified interface for managing barcodes and MPNs across multiple products at once. Instead, it treats each product as a separate item, as it was specifically designed to work with auto parts catalogs that handle products this way. There is no need to worry about this, if you are using SEMA Data, AutoSync, ASAP Network, or any other provider to import products, as barcodes and MPNs will automatically be added to the right fields for every imported item.

Avoid confusing Attributes with the Barcode and MPN fields. When creating a product variation, you'll need to set up attributes, which can be added individually or as part of a predefined product class. Your X-Cart store likely offers multiple pre-installed attributes, including EAN and MPN , which can be found in the Global Attributes section (Catalog › Products › %Your_Item% › Attributes). However, these two attributes are for demonstration only and are NOT connected to the fields supplied through the Barcode and Manufacturer Part Number fields add-on. Do not use them to manage your product's Barcodes and MPNs.

If you wish to remove these fields, go to Catalog › Classes & Attributes › Global Attributes and click the Delete button. Be sure to save your changes afterward.

It is possible to add barcodes and MPNs for product variants.

To do that:

If you leave the barcode field blank for a variant, it will automatically use the barcode of the parent product. This default behavior is indicated in the captions below the column titles (see example below 👇🏻). However, if no Barcode or MPN is specified for the parent product, the corresponding field will remain blank by default.

The CSV file with product information (corresponding to products.csv generated when exporting Products) will include the following additional fields introduced by the Barcode and Manufacturer Part Number Fields add-on:

Variations. In X-Cart 5.6.x, product variations are treated as separate products that come as separate records (lines) in a CSV file.

The add-on adds four new attributes in the CSV files during export/import of product lists:

These attributes are linked to the fields displayed on the product details page. The first two are associated with the Barcode and Manufacturer Part # fields in the Info tab. The rest are related to similar fields located in the Variants tab. You can learn more about them here.

For a better understanding of the example below 👇🏻, we strongly recommend reading the article on importing product variants.

Variations. When using the Product Variations add-on, the CSV files won't include variantupcIsbn and variantmnfVendor fields, as these are not supported by the add-on.

The add-on provides additional filtering options in the Advanced Filters on the product search page, allowing you to narrow down results by barcode or manufacturer part number. If you search without selecting these checkboxes, the results may include products with similar codes in any field (title, description, or specifications). To find an exact item using its identifier, use the search field and check the relevant box ✅.

X-Cart 5.6.x

X-Cart 5.5.1.x

To access the add-on settings, navigate through the following path: Apps -› My Apps -› Barcode and Manufacturer Part Number fields -› Settings (The add-on must be installed and enabled in your store for the Settings link to appear).

Settings page. Here you can choose where to display Barcodes and MPNs. You can select to show them in both the Customer and Admin areas, only in the Admin area, or hide them entirely. The setting applies to both products and their variants.

X-Cart 5.6.x

X-Cart 5.5.1.x

After applying changes, save them by clicking Submit .

As long as the add-on settings specify that the barcode and MPN fields must be visible to both the admin and customer, the storefront visitors will see these details listed under the specifications tab on the product details page. Otherwise, these fields will not be displayed.
