# WooCommerce: A Complete Guide on How to Set GTINs (and Why You Should)
Introduction
In the world of e-commerce, product identification is crucial. Not only does it help you manage your inventory effectively, but it also significantly impacts your product visibility online. One of the most important product identifiers is the Global Trade Item Number (GTIN). This article will guide you through everything you need to know about setting up GTINs in WooCommerce, explaining what they are, why they matter, and how to add them to your products. Setting up GTIN correctly can help increase your product’s discoverability and drive more sales.
What is a GTIN and Why is it Important?
A GTIN (Global Trade Item Number) is a unique identifier used internationally to identify a specific product. Think of it as a product’s fingerprint. There are different types of GTINs, depending on the region and type of product, including:
- UPC (Universal Product Code): Primarily used in North America (GTIN-12).
- EAN (European Article Number): Used in Europe and other regions (GTIN-13).
- JAN (Japanese Article Number): Used in Japan (GTIN-13).
- ISBN (International Standard Book Number): Used for books (GTIN-13).
- ITF-14: Used for outer cases or shipping containers (GTIN-14).
Why are GTINs Important for WooCommerce Stores?
* Improved Product Discoverability: Search engines like Google use GTINs to understand and categorize products accurately. Providing correct GTINs significantly improves your product’s ranking in search results and shopping ads.
* Enhanced SEO: GTINs help search engines match user queries with the correct product listings. This improves your SEO and brings more qualified traffic to your store.
* Increased Sales: Better visibility in search results and shopping platforms directly translates to more potential customers and increased sales.
* Integration with Google Shopping: GTINs are required for many products to be listed on Google Shopping. If you want to leverage this powerful platform, you *must* have GTINs.
* Enhanced Product Matching: Marketplaces and comparison shopping engines use GTINs to match products with the correct information and prevent duplicate listings.
How to Add GTINs to WooCommerce Products
There isn’t a built-in GTIN field in WooCommerce by default, but you can easily add this functionality using plugins or custom coding. Here are a few popular methods:
1. Using a WooCommerce GTIN Plugin
This is the easiest and most recommended method, especially if you’re not comfortable with code. Several excellent plugins are available in the WordPress plugin repository. Here are a few options:
* Product GTIN (EAN, UPC, ISBN) for WooCommerce by WebToffee: A popular, user-friendly plugin specifically designed for adding GTIN fields to your WooCommerce products. It supports various GTIN formats (EAN, UPC, ISBN) and integrates seamlessly with the WooCommerce interface.
* EAN for WooCommerce by Oscar Gare: A lightweight plugin that adds an EAN/GTIN field to your product pages.
* Custom Field Suite: While not specifically for GTINs, Custom Field Suite is a powerful plugin that allows you to add custom fields to your products, including GTIN fields. This provides more flexibility but requires a bit more configuration.
Steps to Add a GTIN Using a Plugin (Example using “Product GTIN (EAN, UPC, ISBN) for WooCommerce by WebToffee”):
1. Install and Activate the Plugin: Go to your WordPress Check out this post: How To Upload Price Tables To Woocommerce dashboard, navigate to *Plugins* > *Add New*, search for “Product GTIN (EAN, UPC, ISBN) for WooCommerce by WebToffee”, install, and activate it.
2. Configure the Plugin (Optional): Most plugins offer settings to customize the field label, validation rules, etc. Check the plugin’s settings page (usually found under *WooCommerce* in your WordPress dashboard).

3. Add GTIN to Products: Edit your product in WooCommerce. You will now see a new field (usually labeled “GTIN”, “EAN”, or “UPC”, depending on the plugin) where you can enter the product’s GTIN.
4. Save Your Product: Click “Update” to save the product with the GTIN.
2. Adding GTINs Using Custom Fields
If you prefer a more hands-on approach or want greater control over the field, you can add GTINs using custom fields. This requires a bit of PHP coding.
/**
function add_gtin_product_field() {
woocommerce_wp_text_input(
array(
‘id’ => ‘_gtin’,
‘label’ => __( ‘GTIN (EAN/UPC)’, ‘woocommerce’ ),
‘placeholder’ => ‘Enter GTIN here’,
‘desc_tip’ => ‘true’,
‘description’ => __( ‘Enter the Global Trade Item Number (GTIN) for this product.’, ‘woocommerce’ )
)
);
}
/
* Save the GTIN field value
*/
add_action( ‘woocommerce_process_product_meta’, ‘save_gtin_product_field’ );
function save_gtin_product_field( $post_id ) {
$gtin = sanitize_text_field( $_POST[‘_gtin’] );
if ( ! empty( $gtin ) ) {
update_post_meta( $post_id, ‘_gtin’, $gtin );
}
}
Explanation:
1. `add_gtin_product_field()`: This function adds a text input field labeled “GTIN (EAN/UPC)” to the “General” tab of the WooCommerce product data meta box.
2. `woocommerce_wp_text_input()`: This is a WooCommerce function that creates a formatted text input field.
- `id`: The unique ID for the field (`_gtin`). The underscore indicates it’s a custom field.
- `label`: The label displayed next to the field.
- `placeholder`: Text displayed inside the field when it’s empty.
- `desc_tip`: Enables a tooltip description.
- `description`: The text displayed in the tooltip.
3. `save_gtin_product_field()`: This function saves the value entered in the GTIN field to the post meta table when the product is saved.
4. `sanitize_text_field()`: Sanitizes the input to prevent malicious code injection.
5. `update_post_meta()`: Updates the product’s post meta with the sanitized GTIN value.
How to Use This Code:
1. Add the Code to `functions.php`: The easiest way is to add this code to your theme’s `functions.php` file. Important: Be very careful when editing `functions.php`. It’s best to use a child theme to avoid losing changes during theme updates. Alternatively, use a code snippets plugin.
2. Edit Your Products: After adding the code, edit your WooCommerce products. You will see the new “GTIN (EAN/UPC)” field in the “General” product data section.
3. Enter GTIN Values: Enter the correct GTIN for each product.
4. Save Your Products: Save the product to store the GTIN value.
3. Importing GTINs via CSV
If you have a large product catalog, adding GTINs manually can be time-consuming. You can use a CSV import/export plugin (such as the built-in WooCommerce CSV importer/exporter or a more advanced plugin like WP All Import) to bulk update your products with GTINs.
Steps:
1. Choose a CSV Import/Export Plugin: WooCommerce has a built-in importer/exporter. Consider WP All Import for more advanced features.
2. Prepare Your CSV File: Create a CSV file with the following columns (at a minimum):
- `ID`: The product ID.
- `SKU`: The product SKU.
- `_gtin`: (If using the custom field method) or the GTIN field name as defined by your plugin.
3. Import Your CSV File: Use the chosen plugin to import the CSV file into WooCommerce. Map the columns in your CSV file to the corresponding fields in WooCommerce (including the GTIN field).
Considerations and Best Practices
- Accuracy is Key: Ensure the GTINs you enter are 100% accurate. Incorrect GTINs can negatively impact your product visibility and may even lead to penalties on some platforms.
- Valid GTINs: Use a GTIN validator to ensure the GTINs are properly formatted and valid. There are several free online GTIN validators available.
- Keep GTINs Updated: If a product’s GTIN changes (e.g., due to packaging changes), update the GTIN in your WooCommerce store accordingly.
- Consider Using a GTIN Database: For large catalogs, consider using a GTIN database or API to automatically look up GTINs based on product information (e.g., brand, model number).
- Check Google Merchant Center Diagnostics: If you’re using Google Shopping, regularly check the “Diagnostics” section in your Google Merchant Center account to identify any issues related to GTINs (e.g., missing GTINs, invalid GTINs).
Conclusion
Adding GTINs to your WooCommerce products is a critical step for improving your online visibility, boosting your SEO, and increasing your sales. By using the methods outlined in this article (plugins, custom fields, or CSV import), you can easily integrate GTINs into your WooCommerce workflow and take your e-commerce store to the next level.
