How to create a new asin in amazon Standard Identification Number (ASIN) for a custom product on Amazon is essential for sellers who want to list unique or private-label items. An ASIN serves as a unique identifier that differentiates your product from others in the marketplace, ensuring accurate tracking, categorization, and searchability. If you’re introducing a custom product, this step is crucial for branding and visibility.

In this guide, we’ll break down the entire process into manageable steps, ensuring you can create a custom ASIN without hassle.


What Is an ASIN, and Why Is It Important for Custom Products?

An Amazon Standard Identification Number (ASIN) is a 10-character alphanumeric code that Amazon assigns to each product in its catalog. For custom products, the ASIN is a key component that ensures your listing is unique and accurately reflects your product’s identity.

  • For custom products: Unlike generic or existing items, custom products require unique ASINs to differentiate your offerings and showcase your brand.
  • ASIN benefits: It helps with inventory management, prevents product mismatches, and enhances visibility in Amazon’s search results.

When Do You Need a New ASIN for a Custom Product?

You’ll need to create a new ASIN if:

  1. You’re launching a completely new product that isn’t currently listed on Amazon.
  2. Your product is a private-label or custom-branded item.
  3. You’re bundling items in a unique way (e.g., a skincare set with your custom branding).
  4. Your product has unique variations, such as different sizes, colors, or configurations.

Step-by-Step Guide to Creating an ASIN for Your Custom Product

Step 1: Prepare Product Information

Before creating an ASIN, gather all the essential details about your product. This includes:

  • Product Title: Clearly describe your product, including brand name, key features, and variations.
  • Product Description: Write a detailed overview of your product’s features, benefits, and uses.
  • Key Features (Bullet Points): Highlight 3–5 key selling points in a concise format.
  • Specifications: Provide size, color, weight, materials, and any other relevant details.
  • Images: Ensure you have high-quality images that meet Amazon’s guidelines (white background, minimum 1000×1000 pixels, and multiple angles).
  • Identifiers: Prepare a Global Trade Item Number (GTIN) like UPC or EAN. If your product qualifies for a GTIN exemption, apply for one in advance.

Step 2: Log in to Amazon Seller Central

Once you have the necessary details, log in to your Amazon Seller Central account. If you don’t have an account yet, you’ll need to sign up as a seller and choose between individual or professional plans.


Step 3: Search for Similar Products

Before creating a new ASIN, ensure your product isn’t already listed in Amazon’s catalog. Use the search function in Seller Central to check by entering a product name, UPC, or other identifiers. If no matching product exists, you can proceed to create a new ASIN.


Step 4: Navigate to “Add a Product”

In the Seller Central dashboard:

  1. Click on the “Inventory” tab.
  2. Select “Add a Product.”
  3. Choose the option: “I’m adding a product not sold on Amazon.”

This will direct you to the product creation page where you can generate a new ASIN.


Step 5: Choose the Correct Category

Amazon’s categories are vast, so selecting the right one ensures your product appears in relevant searches. Use Amazon’s category selector tool to narrow down your options. For example, if you’re selling custom kitchenware, ensure it’s listed under “Home & Kitchen > Kitchen Accessories.”


Step 6: Enter Product Details

This step is critical for creating a compelling and accurate listing. Provide the following details:

  1. Product Name: Include relevant keywords, such as “Custom Bamboo Cutting Board with Personalized Engraving.”
  2. Brand Name: Use your brand’s official name. If you’re not using a registered trademark, ensure consistency across listings.
  3. Manufacturer: Specify your business or the entity producing the item.
  4. Description: Write an engaging description that emphasizes what makes your custom product unique.
  5. Key Features: Add bullet points highlighting unique aspects, such as durability, eco-friendliness, or personalization options.

Step 7: Upload High-Quality Images

Visuals are key to attracting customers. Follow Amazon’s image guidelines, which include:

  • A white background for the main image.
  • At least 1000×1000 pixels to enable zoom functionality.
  • Additional images showcasing multiple angles, usage scenarios, and key features.

Step 8: Set Pricing and Inventory

Determine a competitive price for your product based on market research and production costs. For inventory:

  • If you use FBA (Fulfillment by Amazon): Ship your products to Amazon’s warehouses for storage and fulfillment.
  • If you use FBM (Fulfillment by Merchant): Manage inventory and shipping yourself.

Step 9: Apply for a GTIN Exemption (If Needed)

If your custom product does not have a GTIN (e.g., UPC or EAN), you can apply for a GTIN exemption through Seller Central. This is common for private-label products or handmade items. Ensure you have proof of branding, such as images with your logo.


Step 10: Review and Submit Your Listing

Before finalizing, double-check all details for accuracy and completeness. Preview how your product will appear to customers and make adjustments as needed. Once satisfied, click “Save and Finish.” Amazon will review your submission, and upon approval, your product will receive a unique ASIN and go live on the marketplace.


Pro Tips for Creating an Effective ASIN

  1. Optimize Your Listing for SEO: Use relevant keywords in the product title, description, and bullet points to improve visibility.
  2. Focus on Branding: Custom products thrive on strong branding. Ensure your logo and branding elements are prominent in images and descriptions.
  3. Highlight What Makes Your Product Unique: Emphasize features or benefits that differentiate your product from competitors.
  4. Comply with Amazon Guidelines: Avoid listing violations by adhering to Amazon’s rules on images, descriptions, and pricing.
  5. Monitor Performance: Use Amazon’s Seller Central tools to track your listing’s performance and make data-driven optimizations.

Common Mistakes to Avoid

  1. Failing to Check for Existing Listings: Always search Amazon’s catalog before creating a new ASIN to avoid duplication.
  2. Incomplete Product Details: Missing information can delay approval or lead to poor customer trust.
  3. Poor Quality Images: Subpar visuals can deter potential buyers and hurt your conversion rate.
  4. Ignoring SEO: Without proper keywords, your product may struggle to rank in search results.
  5. Overlooking GTIN Requirements: Ensure you have a valid UPC or apply for a GTIN exemption if necessary.

Why Creating a Unique ASIN Matters for Custom Products

A unique ASIN is essential for protecting your brand, ensuring accurate product representation, and boosting search visibility. For custom products, it’s also a way to assert ownership and prevent other sellers from piggybacking on your listing.


Conclusion

Creating an ASIN for your custom product on Amazon may seem daunting, but breaking it into manageable steps simplifies the process. From gathering product details to optimizing your listing for SEO, every step contributes to the success of your product on Amazon’s marketplace. With proper preparation and attention to detail, you can ensure your custom product stands out, attracts customers, and drives sales.
