Barcode System for Amazon Sellers: FBA and Beyond

Mastering the Barcode System for Amazon Sellers

Fast-growing Amazon sellers can no longer rely on spreadsheets or sporadic scanning. Today's marketplace demands precision and compliance – requirements fulfilled by an effective barcode system for amazon sellers that serves as the backbone for both FBA and merchant-fulfilled operations.

Amazon's ecosystem depends on barcodes to track millions of products through complex fulfillment networks. Sellers must understand various barcode types, meet strict amazon fba barcode requirements, implement error-free labeling, and select appropriate tools to succeed.

This guide navigates essential barcode knowledge, from decoding UPC, EAN, GTIN, and FNSKU codes to establishing warehouse workflows that prevent costly errors. We'll explore label printing best practices, compliance pitfalls, and achieving barcode tracking system functionality across multiple sales channels.

Throughout these sections, you'll discover how Finale Inventory offers integrated solutions designed specifically for Amazon sellers' unique challenges.

The Role of Barcodes in Amazon Success

Barcodes serve as the invisible backbone of Amazon's operational excellence, driving the incredible fulfillment speed and accuracy that both sellers and customers have come to expect. In Amazon's ecosystem, barcodes transform physical products into digitally trackable assets that can be seamlessly monitored throughout the entire supply chain.

Merchant-Fulfilled vs. FBA Workflows

For merchant-fulfilled sellers, barcodes primarily facilitate inventory tracking within their own warehouses. These sellers manage their own barcode systems, scan products during picking, and handle shipping labels. The accuracy of their inventory counts directly impacts their ability to maintain strong seller ratings.

In contrast, FBA (Fulfillment by Amazon) leverages barcodes more extensively. When inventory arrives at Amazon fulfillment centers, each item is scanned, verified, and assigned a specific storage location. These barcodes enable Amazon's algorithms to optimize storage and create efficient picking paths, reducing errors and processing time.

The integration of proper barcode protocols directly affects your metrics. Sellers with consistent barcode implementation see fewer inventory discrepancies, faster shipping times, and ultimately higher seller ratings – which can boost visibility in Amazon's search results.

For businesses seeking a comprehensive approach, implementing a complete barcode inventory system creates the foundation for reliable tracking across all sales channels. Those looking to fine-tune processes will find barcode inventory management provides deeper controls to enhance fulfillment operations.

Decoding Amazon Barcode Types: UPC, EAN, GTIN, FNSKU

When selling on Amazon, understanding the various barcode systems is essential for inventory success. Each code serves a specific purpose in the e-commerce logistics ecosystem.

Universal Product Codes (UPC)

UPCs are 12-digit numeric codes primarily used in North America. Manufacturers purchase these from GS1, and they identify products across retail channels. Before listing on Amazon, verify code authenticity using a upc validator to prevent errors.

European Article Numbers (EAN)

EANs are 13-digit numeric codes used internationally. These function similarly to UPCs but are more common in Europe and global markets. Amazon accepts EANs for international sellers.

Global Trade Item Numbers (GTIN)

GTINs represent the overarching family of product identifiers that include both UPCs and EANs. When Amazon requests a GTIN, sellers can provide either a valid UPC or EAN.

Fulfillment Network Stock Keeping Unit (FNSKU)

For sellers using Amazon FBA, amazon fba barcodes typically default to FNSKUs. These Amazon-specific identifiers link directly to your seller account and prevent commingling inventory with other sellers.

When creating listings in amazon seller central barcode options determine how products are identified within Amazon's fulfillment network. FNSKUs often supersede manufacturer UPCs because they provide Amazon-specific tracking capabilities.

Externally Visible Barcodes	Internal Warehouse Barcodes
UPC/EAN (on retail packaging)	FNSKU (Amazon warehouse label)
Manufacturer barcodes	Location identifiers
Shipping labels	Sortation codes

Using proper barcode inventory management processes ensures your Amazon operation maintains accuracy from listing creation through final delivery.

Navigating Amazon FBA Barcode Requirements and Compliance Risks

Amazon's barcode requirements are stringent but essential for smooth fulfillment operations. Understanding these specifications helps prevent costly delays and penalties.

Amazon's Current Barcode Specifications

Amazon fba barcode requirements include:

Print resolution: Minimum 300 DPI
Quiet zone: 0.25 inches of white space around the barcode
Size requirements: 1-2 inches in height, proportionally sized
Placement: Flat surfaces only, never on corners or seams

Quality barcode printing equipment is recommended to avoid scanning failures.

Protection Through Compliance

Proper amazon compliance barcoding serves as a safeguard by enabling Amazon to:

Track products throughout their warehouse network
Accurately fulfill orders
Process returns correctly
Prevent commingling with similar products

Non-compliant barcodes increase the risk of unfulfillable returns where products can't be properly identified.

Consequences of Non-Compliance

Failing to meet requirements can result in:

Receiving delays from manual processing
Additional labeling fees ($0.20-$0.30 per unit)
Stranded inventory that can't be sold
Account performance penalties

For this reason, many successful sellers implement barcode inventory systems ensuring compliance throughout their supply chain.

Printing & Applying Labels for FBA Shipments

Sending inventory to Amazon FBA requires precise label management to ensure your products move efficiently through the fulfillment network. Mastering product labeling for Amazon is a critical skill that directly impacts your selling success.

Implementation steps

Start by determining whether to generate labels through Seller Central or your warehouse management system. Seller Central provides a straightforward option for smaller sellers, generating compliant labels directly from your inventory list. For businesses with higher volume, a third-party WMS integration can automate this process, reducing manual steps and potential errors.

Printer selection significantly impacts label quality and durability. Thermal printers are the industry standard for Amazon sellers because they produce clear, scan-ready barcodes without ink costs. Choose label materials that adhere well to your product packaging but won't damage items if removal is necessary. Waterproof options are essential for products that might experience temperature changes during shipping.

Before applying labels to your entire inventory, always test several samples using a barcode scanner for inventory to verify readability. Poor scannability will trigger rejection at Amazon's receiving docks, causing costly delays.

For optimal application:

Print labels in batches matching your packing workflow
Verify each label is scannable before applying
Position labels on a flat, accessible surface of the product
Avoid placing over existing barcodes or critical product information
Document your labeling process for training and quality control

New sellers without established product codes should explore a reliable barcode generator to create compliant GTINs for their products. These unique identifiers are required for Amazon listing creation and must follow GS1 standards for marketplace acceptance.

Common Pitfalls: Mismatched Codes, Double Labeling & Unreadable Tags

Establishing an effective Amazon FBA operation means avoiding these common barcode pitfalls:

Wrong SKU-to-barcode mapping: When products receive incorrect barcodes, inventory discrepancies and customer complaints follow. Solve this with systematic verification scans at multiple workflow points to catch mismatches before shipment. A proper barcode tracking system ensures products match their digital identifiers.
Double labels causing mis-reads: Overlapping labels confuse scanners. Teach proper peel-and-stick best practices, emphasizing complete removal of old labels before applying new ones.
Smudged labels after transit: Environmental factors can make barcodes unreadable. Use quality thermal printing equipment and implement pre-shipment quality checks to ensure barcode labels remain scannable throughout fulfillment.

Proactive preparation prevents these errors, ensuring smooth inventory flow through Amazon's fulfillment centers while avoiding account penalties.

Integrating a Barcode System for Amazon Sellers Into Daily Warehouse Workflows

Amazon sellers face unique inventory challenges that require precise tracking to maintain good marketplace standing. A properly implemented barcode system transforms chaotic operations into a streamlined process with accountability at every step.

Workflow deep dive

Receiving: When inventory arrives, team members can immediately validate each FNSKU against expected inventory and assign storage locations with a simple scan. This initial validation prevents costly errors before products enter your fulfillment pipeline.

Wave or batch order picking: With mobile-guided instructions, pickers follow the most efficient path through your warehouse, reducing walking time and eliminating errors. For complex operations, see our guide on order picking implementation.

Packing & shipping: The final verification scan before carrier hand-off prevents customer dissatisfaction by:

Cross-referencing picked items against order details
Validating package weights to catch quantity errors
Generating carrier-compliant shipping labels with tracking

KPI tracking: Monitor essential metrics like mis-pick rate, pick velocity, FBA inbound accuracy, and inventory location accuracy to drive continuous improvement. Amazon sellers who implement these performance measures see measurable improvements in their seller metrics, particularly addressing the "wrong item sent" defect rate that impacts account health.

Multi-Channel Inventory Visibility Beyond Amazon

Amazon sellers often manage inventory across multiple sales channels, making a unified barcode inventory system essential for accurate tracking and operational efficiency.

Expansion angles

Using one barcode per SKU across Shopify, eBay, and Amazon creates a single source of truth for your products. When receiving inventory, one scan updates quantities across all platforms, preventing costly overselling incidents and simplifying warehouse operations.

The sync logic between channels becomes critical when managing both FBA and FBM inventory. Effective barcode inventory management systems automatically adjust available quantities when items are committed to either fulfillment method, ensuring you never promise the same inventory twice.

For businesses handling regulated or high-value products, implementing serial or lot number tracking provides enhanced visibility. This advanced functionality, explored in our barcode tracking system guide, enables precise traceability throughout your supply chain.

Multi-channel barcode systems reach their full potential when paired with platform-specific tools like a shopify barcode scanner that synchronize physical inventory with digital storefronts in real-time.

Frequently Asked Questions

What barcode system does Amazon use?

Amazon primarily uses two barcode systems: UPCs/GTINs for product identification and FNSKUs (Fulfillment Network Stock Keeping Units) for warehouse management. UPCs are standard retail barcodes required for product listings, while FNSKUs are Amazon-specific barcodes applied to products sent to fulfillment centers. These FNSKUs help Amazon track your specific inventory separately from identical products from other sellers. If you use Amazon's labeling service, they'll apply FNSKUs for you, though this incurs additional fees.

Can I create my own barcode to sell on Amazon?

No, you cannot simply create your own barcodes for Amazon listings. Amazon requires authentic UPC, EAN, ISBN, or GTIN codes purchased from GS1, the official global barcode issuing organization. Using unauthorized "cheap" barcodes from resellers violates Amazon's terms and can result in listing removal or account suspension. In limited circumstances, you can apply for a GTIN exemption if your products genuinely don't qualify for standard barcodes, but this is the exception rather than the rule.

How to get barcodes for Amazon?

To get legitimate barcodes for Amazon:

Purchase official UPC/EAN codes from GS1 (www.gs1.org) – the only Amazon-approved source
Register for a company prefix based on your anticipated product volume
Assign individual barcodes to each product variation (size, color, etc.)
Generate the barcode images using barcode generator software or GS1's tools
Apply for a GTIN exemption only if your product category qualifies

Avoid barcode resellers, as Amazon now validates codes against the GS1 database.

Do I need a GS1 barcode to sell on Amazon?

Yes, Amazon requires GS1-issued barcodes (UPC, EAN, JAN, or ISBN) for most product listings. While Amazon previously accepted barcodes from any source, they now validate codes against the GS1 database. Using unauthorized barcodes risks listing removal and account penalties. The only exceptions are products that qualify for GTIN exemptions (like private label, handmade, or certain categories) or if you're using manufacturer barcodes for products you're authorized to sell. GS1 membership requires annual fees, but it's considered an essential business expense for legitimate Amazon sellers.

Are suppliers required to have UPC or ISBN barcodes for items/books being sold on Amazon?

Yes, suppliers must provide valid UPC barcodes for general items and ISBN barcodes for books when selling on Amazon. These identifiers are mandatory for product listings and catalog matching. Books must have ISBNs, while most other products require UPCs or EANs. If you're sourcing wholesale products, legitimate suppliers should include these barcodes on packaging. For private label products, you'll need to obtain your own GS1-issued barcodes. Non-compliance can result in listing issues or removal.

Does Amazon have a GTIN Exemption Policy?

Yes, Amazon does offer a GTIN (Global Trade Item Number) Exemption policy for specific situations. You can apply for this exemption when your products genuinely cannot use standard barcodes, such as handmade items, private label products with small production runs, or certain category-specific items. To request an exemption, you must submit a form in Seller Central with detailed product information and evidence explaining why your items cannot use standard identifiers. Approval is not guaranteed and Amazon evaluates each request individually.

What does the seller need to know about the two barcodes on the labels they printed?

When sellers print Amazon labels, they often include two barcodes: the product barcode (UPC/EAN) and the Amazon FNSKU barcode. The product barcode identifies what the item is across all retail channels, while the FNSKU identifies this specific unit as belonging to your seller account within Amazon's system. The FNSKU prevents commingling your inventory with other sellers' identical products. When shipping to FBA, the FNSKU must be clearly visible and scannable. If both barcodes appear on your label, ensure they're properly spaced to avoid scanning confusion.

Do you need to use an FNSKU for your Amazon product?

Using FNSKUs for your Amazon products is highly recommended, though not always mandatory. FNSKUs prevent your inventory from being commingled with other sellers' identical products, protecting you from potential quality issues, customer complaints, and account problems stemming from another seller's items. If you opt out of using FNSKUs (called "stickerless commingled inventory"), Amazon will treat identical products as interchangeable across sellers. For brand owners, unique products, and quality-sensitive items, using FNSKUs is the safer choice despite the additional labeling step.

How to create an FNSKU?

To create FNSKUs for your Amazon products:

Log into Seller Central and navigate to "Inventory" → "Manage Inventory"
Find the product and click "Print Item Labels" or select multiple items and use "Action" → "Print Item Labels"
Choose your label specifications (number of labels, paper type)
Download and print the PDF containing your FNSKU barcodes
Alternatively, create FNSKUs during the FBA shipment creation process when selecting labeling preferences

Each FNSKU is unique to both your seller account and the specific product.

How to label your products with an FNSKU barcode?

To properly label products with FNSKU barcodes:

Print labels on white, non-reflective label paper (standard sizes: 1" x 2", 1" x 3", or 2" x 3")
Ensure 300 DPI print quality for reliable scanning
Apply labels flat (not wrapped around corners) on a clean, dry surface
Cover any existing barcodes completely to prevent scanning confusion
Place labels in a consistent, accessible location that won't damage the product
For polybags, place labels outside the bag on a flat surface
For multipacks, label the outer packaging, not individual items

Properly applied labels reduce rejection rates at Amazon fulfillment centers.

What does Amazon require for barcode labeling?

Amazon's barcode labeling requirements include:

Labels must be printed at 300+ DPI on non-reflective white labels
Barcodes must be scannable with proper quiet zones (margins) around them
Each product variation needs a unique barcode (size, color, etc.)
Labels must completely cover any original barcodes
FNSKUs must be visible and not wrapped around corners or edges
For FBA shipments, the label must match the exact product in your shipment plan
Expiration dates must be visible on applicable products
Polybags must have suffocation warnings and barcodes outside the bag

Non-compliance can result in refused shipments or additional service fees.

How do I print labels that meet Amazon’s requirements?

To print Amazon-compliant labels:

Use a thermal or laser printer (inkjet printers often produce lower quality barcodes)
Set print quality to at least 300 DPI
Use proper label sizes (1" x 2", 1" x 3", or 2" x 3" are standard)
Select non-reflective white label paper with permanent adhesive
Test scan barcodes before applying to ensure readability
Avoid stretching or distorting the barcode image
Print from Amazon's provided PDF files without rescaling
Ensure proper contrast (black bars on white background)

A barcode generator tool or specialized label software can help create professional-quality labels consistently.

Can I use the same barcode for Amazon and my own store?

Yes, you can use the same product barcode (UPC/EAN) for both Amazon and your own store, which actually helps maintain consistent inventory tracking across channels. The UPC identifies the product itself, regardless of where it's sold. However, for fulfillment processes, you'll use different systems: Amazon uses FNSKUs for their warehouses, while your own store will likely use your internal SKU system for barcode inventory management. When using a barcode inventory system, ensure it can associate multiple identifiers (UPC, FNSKU, internal SKU) with the same product to prevent confusion.

What happens if my barcode is unreadable at an Amazon warehouse?

If your barcode is unreadable when it arrives at an Amazon fulfillment center, several things might happen:

Amazon may reject the entire shipment, returning it at your expense
They might apply their own labels and charge a per-item labeling fee ($0.20-$0.30 per unit)
Your inventory could be marked as "unfulfillable" and held in limbo
Processing may be significantly delayed, affecting your selling ability

To avoid these issues, always use high-quality printers, proper label materials, and test scan barcodes before shipping. Consider using a dedicated barcode printing system rather than standard office printers for better reliability.

How do I track inventory across Amazon and other channels?

To effectively track inventory across Amazon and other sales channels:

Implement a centralized inventory management system that syncs with all your sales channels
Use a consistent SKU structure across platforms for easy cross-reference
Configure real-time inventory updates to prevent overselling
Utilize barcode scanning for accurate receiving, picking, and shipping processes
Set buffer stock levels for popular items to account for sync delays
Regularly reconcile inventory counts between physical stock and digital records
Consider solutions like Finale Inventory that specialize in multi-channel inventory synchronization

This approach creates a single source of truth for your inventory regardless of sales channel.

How can I avoid double labeling errors?

To avoid double labeling errors when preparing Amazon inventory:

Establish a standardized workflow for product labeling
Use a barcode scanner to verify each product before applying new labels
Completely cover original barcodes when applying FNSKUs to prevent confusion
Train staff on proper label placement and the importance of covering existing codes
Implement quality control checks before shipment to catch mistakes
Consider using a barcode inventory system that tracks which products have already been labeled
Use different colored labels for different purposes to visually distinguish them
Batch similar products together to reduce context-switching errors

These practices significantly reduce costly rejections and returns.

Which barcode scanners work best for FBA prep centers?

For FBA prep centers, the most effective barcode scanners are:

Wireless Bluetooth scanners like Zebra DS2278 for mobility around packing stations
2D-capable scanners that can read both traditional barcodes and QR codes
Industrial-grade scanners with image capture for documenting condition issues
Mobile computer scanners (e.g., Zebra TC series) that integrate scanning with inventory apps
Hands-free presentation scanners for high-volume processing stations

Look for scanners with Amazon-compatible data formatting, rugged construction for warehouse environments, and quick reconnection capabilities. A quality shipping barcode scanner pays for itself through improved accuracy and efficiency.

How does a barcode system improve FBA preparation efficiency?

A barcode system dramatically improves FBA preparation efficiency by eliminating manual data entry and verification steps. Warehouse staff can scan products to instantly confirm correct items, apply accurate labels, and verify proper packaging. Batch scanning capabilities allow for processing multiple units simultaneously, while integration with inventory management software ensures stock levels remain accurate. Advanced systems like Finale Inventory provide FBA-specific workflows that guide workers through Amazon's preparation requirements, reducing errors by up to 95% and processing shipments up to 4x faster than manual methods.

What’s the difference between using Amazon’s labeling service versus managing barcodes in-house?

Amazon's labeling service offers convenience but at a cost of $0.20-$0.30 per unit, which quickly adds up for high-volume sellers. While it eliminates the need for label printers and application time, it relinquishes control over label placement and quality. In-house labeling gives you complete oversight of the process, allows for quality control checks, integration with your existing inventory system, and significant cost savings at scale. For sellers shipping 1,000+ units monthly, implementing an in-house barcode system typically delivers ROI within 3-6 months through combined labor and fee savings.

How can Finale Inventory help Amazon sellers manage barcodes more effectively?

Finale Inventory helps Amazon sellers manage barcodes more effectively by providing a comprehensive system that bridges Amazon's requirements with efficient warehouse operations. The software automatically generates and tracks FNSKUs while maintaining relationships with UPCs and internal SKUs, preventing costly identification errors. Its mobile barcode scanning app guides warehouse staff through FBA prep processes with step-by-step verification, ensuring compliance with Amazon's strict requirements.
