That is usually too late. Once your products move across channels, countries, or warehouse partners, barcode quality stops being an admin task and starts becoming part of your operational foundation. The right barcode setup helps you: - reduce manual errors - speed up inbound receiving - create a cleaner data foundation across systems - improve lot, expiry, and serial number tracking - scale more easily across sales channels, warehouses, and countries This is exactly what the GS1 standard was built for. GS1 barcodes are not just about getting a product scanned. They help make sure every system involved in selling, storing, and shipping your product knows exactly what it is. ## What is a GS1 barcode? A GS1 barcode has two parts worth separating in your head: the **identifier** and the **format**. The identifier is a **GTIN** (Global Trade Item Number). It's a unique number assigned to one specific product variant, your 250ml bottle, your size-M blue t-shirt, your 1kg supplement bag with vanilla taste. Each variant gets its own GTIN, issued through GS1, and no other product anywhere in the world shares that number. The format is the barcode itself: the visual pattern of bars that encodes the GTIN so scanners can read it. The most common formats are **EAN-13** (13 digits, standard across Europe and most of the world) and **UPC-A** (12 digits, standard in North America). Same idea, different regional conventions. Why this distinction matters: the GTIN is the product's identity, and the barcode is just one way to carry it. The same GTIN can also be embedded in a 2D code, sent in a product feed to Google Shopping, listed in an Amazon catalog, or stored in your ERP. Once a product has a GTIN, every system in your supply chain has a shared way to refer to it, without anyone needing to agree on internal SKUs or product names. That's the real value of GS1. Not the bars on the box, but that a retailer in Berlin, a marketplace in Paris, and a 3PL in London can all recognize your product as the same item, instantly, without ever talking to each other.   ![GS1 barcode strucuture](https://blog.getbyrd.com/hs-fs/hubfs/GS1%20barcode%20strucuture.png?width=1200&height=800&name=GS1%20barcode%20strucuture.png) ## How to get GS1 barcodes as a manufacturer or brand owner If you make or own the product, the right path is to register directly with your local GS1 member organization, for example [GS1 Germany](https://gs1.eu/create-account/) or [GS1 UK](https://www.gs1uk.org/). Avoid third-party barcode resellers. Recycled or unofficial codes can cause listing suppression on marketplaces and create traceability problems down the line. Once registered, you receive a **GS1 Company Prefix**. This is a unique number tied to your brand, and it forms the base of every GTIN you create. From there, you assign a unique GTIN to each product variant. For example: - a 250ml bottle gets a different GTIN than the 500ml version - a blue t-shirt in size M gets a different GTIN than the same shirt in size L - a multipack usually needs a different GTIN than the single unit One thing worth knowing: GS1 standards require a new GTIN whenever a product is new to market or has a meaningful change in packaging. Barcode governance should sit with your product and operations teams, not only with whoever designs the box. If you resell products rather than manufacture them, work with the GTIN the brand owner already assigned and verify it through the [Verified by GS1 database](https://www.gs1.org/services/verified-by-gs1) when needed. ## How to use GTINs as a merchant The smartest move is to make the GTIN the shared product identity across your shop, marketplaces, ERP, and 3PL. That means the same product identifier should be used wherever product data moves between systems or companies. This matters because GTINs are not only useful in warehouse operations. They are also important for marketplace and shopping feed performance. Google, for example, uses unique product identifiers such as GTINs to distinguish products in the global marketplace, and product variants such as different sizes or colors need their own unique identifiers. For growing brands, this creates a cleaner foundation from day one: > A valid GTIN helps marketplaces, retailers, warehouses, and logistics partners speak the same product language. ## What changes in the warehouse This is where GS1 becomes operationally valuable in a way that basic barcodes simply cannot match. A basic internal barcode usually answers one question: **Which SKU is this?** GS1 barcodes can go further. For example, GS1-128 barcodes can carry the product identity alongside additional information such as batch or lot number, expiry date, or serial number. That makes warehouse processes faster and less error-prone. - **Faster inbound receiving**Warehouse teams can scan structured product data instead of checking and entering details manually. - **Fewer manual errors**Product identity, batch numbers, expiry dates, and serial numbers can be captured directly from the barcode. - **Less re-labeling**If the manufacturer label already contains the right data, the warehouse does not need to create workarounds. - **Better lot and expiry tracking**This is especially important for [supplements, food products](https://www.getbyrd.com/en/food-beverages), [cosmetics](https://www.getbyrd.com/en/beauty-health), [pet supplies](https://www.getbyrd.com/en/pet-supplies), and other items where FIFO or FEFO processes matter. - **Cleaner operations across multiple warehouses** Standardized identifiers make it easier to transfer stock, work with multiple fulfillment locations, and keep data consistent. - **Identifiers that scale beyond the product** GS1 also covers cases (ITF-14) and logistics units such as pallets or parcels (SSCC), not just individual items. The big advantage is not the barcode itself. It is the data quality behind it. > Warehouses don't lose time on scanning. They lose time on everything that happens when a scan isn't enough. --- --- ## Why GS1 barcodes matter for growing brands Barcode strategy is fulfillment strategy. The earlier you standardize product identification, the easier it becomes to scale without friction. For brands, that matters when: - **Adding a second sales channel.** The first marketplace usually accepts whatever identifiers you give it. The second one almost always demands valid GTINs, and listings get suppressed without them. - **Entering a regulated category.** Supplements, cosmetics, food, and pet products bring lot tracking, expiry dates, and traceability requirements that are far easier to meet when the data is already encoded in the barcode. - **Adding a second warehouse.** Stock transfers, cross-location picking, and consistent reporting all depend on every system referring to the same product in the same way. Internal SKUs alone stop working at this point. - **[Switching or upgrading 3PLs.](https://www.getbyrd.com/en/3pl-switch)** A migration with clean GS1 data takes days. A migration without it turns into weeks of re-labeling, mapping, and exception handling. - **Selling cross-border in the EU.** Different countries, different carriers, different retail partners, all of which assume GS1 as the baseline. The pattern is consistent: brands rarely run into barcode problems when they're small. They run into them the week they try to do something new. Putting the foundation in place beforehand is the difference between a launch and a scramble.   ## Can byrd handle GS1 barcodes in fulfillment? Yes. [byrd's fulfillment solution](https://www.getbyrd.com/en/fulfillment) supports GS1 barcodes across the entire warehouse process. Inbound receiving, stock management, pick and pack, and outbound shipping all work with GS1-compliant labels and identifiers. If your products carry EAN-13, ITF-14, or GS1-128 labels, byrd's systems can read and process them as part of the operational workflow. For merchants who [track lots](https://blog.getbyrd.com/en/lot-tracking?hsLang=en), [serial numbers](https://blog.getbyrd.com/en/serial-number-tracking?hsLang=en), or best-before dates, byrd captures that data at scan time using the Application Identifiers encoded in GS1-128 barcodes. That means FIFO-driven picking, lot traceability, and expiry management are handled automatically rather than manually. As mentioned above, that is especially valuable for categories such as: - [Supplements and food products](https://www.getbyrd.com/en/food-beverages) - [Cosmetics and beauty products](https://www.getbyrd.com/en/beauty-health) - [Pet supplies](https://www.getbyrd.com/en/pet-supplies) If you ship across multiple EU countries or work with [multiple warehouse locations](https://www.getbyrd.com/en/european-fulfillment-network), GS1 compliance also makes cross-location stock transfers and carrier handoffs significantly cleaner. For e-commerce brands shipping between 1,000 and 100,000 orders a month across Europe, byrd combines GS1-ready warehouse operations with straightforward integrations into [Shopify](https://www.getbyrd.com/en/shopify-fulfillment), [Shopware](https://www.getbyrd.com/en/shopware-fulfillment), and many more [shop systems, marketplaces, and modern ERP systems](https://www.getbyrd.com/en/all-integrations), so the infrastructure works without building it yourself. ## Conclusion GS1 barcodes are more than a packaging detail. They are a practical way to create cleaner product data, reduce manual errors, and make warehouse processes faster. For growing brands, this matters long before fulfillment becomes complex. The earlier you standardize your product identifiers, the easier it becomes to expand across channels, markets, and warehouse locations. A barcode may look small on the packaging, but the operational impact behind it can be significant.  ---     ## As seen on               [![Getbyrd](https://blog.getbyrd.com/hubfs/raw_assets/public/Getbyrd_May2021/images/Footer_logo.svg "Getbyrd")](https://getbyrd.com/en/) - Services - [Fulfillment](https://getbyrd.com/en/fulfillment) - [New Businesses](https://getbyrd.com/en/new-businesses) - [Established Retailers](https://getbyrd.com/en/established-retailers) - [Enterprises](https://getbyrd.com/en/enterprise) - [European Fulfillment Network](https://getbyrd.com/en/european-fulfillment-network) - Integrations - [Amazon FBM](https://getbyrd.com/en/amazon-fulfillment) - [Billbee](https://getbyrd.com/en/billbee-fulfillment) - [Mirakl](https://getbyrd.com/en/mirakl-fulfillment) - [ChannelEngine](https://getbyrd.com/en/integration-channelengine) - [PlentyONE](https://getbyrd.com/en/plentymarkets-fulfillment) - [PrestaShop](https://getbyrd.com/en/integration-prestashop) - [Shopify](https://getbyrd.com/en/shopify-fulfillment) - [Shopware](https://getbyrd.com/en/shopware-fulfillment) - [WooCommerce](https://getbyrd.com/en/woocommerce-fulfillment) - [Xentral](https://getbyrd.com/en/xentral-integration) - Locations - [Logistics Locations Europe](https://getbyrd.com/en/european-fulfillment-network) - [UK](https://getbyrd.com/en/european-fulfillment-network/uk) - [Austria](https://getbyrd.com/en/european-fulfillment-network/austria) - [France](https://getbyrd.com/en/european-fulfillment-network/france) - [Germany](https://getbyrd.com/en/european-fulfillment-network/germany) - Partner - [Become a partner](https://getbyrd.com/en/partnerships) - About us - [Team](https://getbyrd.com/en/team) - [Blog](https://blog.getbyrd.com/en) - [Our Customers](https://getbyrd.com/en/references) - [Press](https://getbyrd.com/en/press) - [Career](https://getbyrd.com/en/jobs) - [Sustainability](https://getbyrd.com/en/sustainability-at-byrd) - Additional links - [Terms and Conditions](https://getbyrd.com/en/tac) - [Privacy Policy](https://getbyrd.com/en/privacy) - [Imprint](https://getbyrd.com/en/imprint) - [Contact](https://getbyrd.com/en/contact) - [Help](https://support.getbyrd.com/en/knowledge-base) ```json { "@context" : "https://schema.org", "@type" : "BlogPosting", "author" : { "@type" : "Person", "name" : "Phillip Pitsch", "url" : "https://blog.getbyrd.com/en/author/phillip-pitsch" }, "dateModified" : "2026-06-30", "datePublished" : "2026-04-28", "description" : "GS1 barcodes help brands reduce warehouse errors, speed up inbound, and create cleaner product data.
