Introduction
Every product sold on Amazon is identified by a unique ASIN — the Amazon Standard Identification Number. This small alphanumeric code might look simple, but it’s one of the most important pieces of Amazon’s massive product catalog system.
If you’re introducing a new product to the marketplace — one that doesn’t already exist — you’ll need to create a new ASIN.Done correctly, this process allows Amazon to recognize your product as unique, link it to your brand, and make it searchable for buyers worldwide.
In this WalBayZon guide, we’ll explain everything you need to know about ASIN creation, including:
What an ASIN is
When to create a new one
How to add it through Seller Central
Documentation and brand requirements
Common issues and how to avoid listing rejection
What Is an ASIN?
ASIN stands for Amazon Standard Identification Number.It’s a 10-character alphanumeric code assigned to every product listed on Amazon.
For example:
A particular phone model, say “Samsung Galaxy S24 128GB Black,” will have one ASIN.
Every seller listing the same model shares that same ASIN.
If you introduce a new variant (e.g., a 256GB model or a unique bundle), that may require a new ASIN.
Amazon uses ASINs to:
Index listings across global marketplaces
Track inventory
Prevent duplicate listings
Ensure accurate search results
Group identical products together
When You Should Create a New ASIN
You only create a new ASIN if your product doesn’t already exist in Amazon’s catalog.
✅ Create a New ASIN If:
Your product is brand new and not listed by anyone else.
You’re launching a private label product.
You’re creating a new bundle (two or more items packaged together uniquely).
Your product has a unique variation (new size, color, or design) not available under existing ASINs.
You’re registered brand owner launching a new line.
🚫 Don’t Create a New ASIN If:
The same product already exists under another ASIN.
You’re reselling an existing product.
Only packaging or pricing differs (same item, same model = same ASIN).
Duplicate ASIN creation can lead to suppression or account warnings — so always search first.
How to Check Whether a Product Already Has an ASIN
Before you begin:
Log in to your Amazon Seller Central.
Go to Inventory → Add a Product.
Enter your product name, brand, or barcode (UPC, EAN, or ISBN).
If the product appears, it means the ASIN already exists.
In that case, click “Sell this product.”
If it does not appear, select “I’m adding a product not sold on Amazon.”
You’ll now be guided to create a new ASIN for your item.
Step-by-Step: How to Create a New ASIN
Here’s the complete process summarized for clarity:
Step 1: Navigate to Add a Product
In Seller Central, go to Inventory → Add a Product.This tool allows you to either match an existing ASIN or create a new one.
Step 2: Select “I’m Adding a Product Not Sold on Amazon”
If Amazon’s catalog doesn’t show your product, choose this option to start fresh.
Step 3: Choose the Correct Product Category
Accurate categorization is vital for visibility and compliance.For example:
Clothing & Accessories → Women’s Scarves → Satin Scarf
Beauty & Personal Care → Face Creams → Firming Cream
Wrong categories can cause your product to appear in irrelevant search results or be suppressed.
Step 4: Fill in Product Vital Info
This includes:
Product Title – concise, keyword-rich, and compliant
Brand Name – exactly as registered or as printed on packaging
Manufacturer Details
Model/Part Number (if applicable)
Ensure your brand name matches your packaging and trademark; inconsistency can lead to listing rejection.
Step 5: Enter Product ID (UPC / EAN / GTIN)
Amazon requires a unique identifier such as:
UPC (Universal Product Code)
EAN (European Article Number)
ISBN (for books)
If your brand has GTIN Exemption approval, you can skip this.WalBayZon can assist in filing GTIN exemption requests for custom or handmade products.
Step 6: Add Product Images
High-quality images are non-negotiable. Amazon requires:
Minimum 1000 × 1000 pixels
White background for the main image
Clear product visibility (no watermarks or text overlays)
Additional lifestyle or detail images (up to 7 per listing)
Images are key to conversion — they must be realistic, compliant, and polished.
Step 7: Write Bullet Points and Description
Here’s your chance to highlight your product’s unique features and benefits.
Use 5 concise bullet points.
Focus on benefits first, features second.
Maintain keyword relevance.
Write an engaging product description (200–300 words) that tells your brand story.
Example:“Crafted from premium satin fabric, this lightweight scarf adds a touch of sophistication to any outfit while ensuring comfort throughout the day.”
Step 8: Provide Product Details & Dimensions
Include:
Weight
Dimensions (length × width × height)
Material or ingredients
Intended use / care instructions
Compliance or certification (if applicable)
Accurate details reduce return rates and build buyer trust.
Step 9: Set Offer Information
Under the Offer Tab, fill in:
SKU (Stock Keeping Unit) – your internal product ID.
Price – retail or promotional price.
Quantity – available stock.
Condition – always “New” for new ASINs.
Fulfillment method – choose between:
FBA (Fulfilled by Amazon) – Amazon handles storage, packaging, and shipping.
FBM (Fulfilled by Merchant) – You handle order processing and delivery.
Step 10: Save & Publish
Review your submission.
Assign a new ASIN upon approval.
Display your listing on the marketplace.
If any mandatory fields are missing, Amazon will highlight them before submission.
Key Documents You May Need
Some categories require additional documentation before Amazon activates your ASIN:
Document | Purpose |
Brand Authorization Letter / Trademark Certificate | Confirms your ownership or right to sell under that brand |
Safety Certificate / Test Report | For electronics, cosmetics, kids’ products |
FSSAI License | For food and beverage products |
Import / Compliance Docs | For imported goods |
Product Images of Packaging | To verify brand name and labeling |
GTIN Exemption Approval (if applicable) | For custom or handmade products |
WalBayZon assists clients in preparing all such paperwork before ASIN creation to ensure zero rejection.
Common Errors & How to Avoid Them
Duplicate Listings – Search thoroughly before creating a new ASIN.
Incorrect Brand Field – Must match registered name exactly.
Image Violations – Avoid borders, collages, or logos overlaid.
Missing Attributes – Amazon will suppress listings missing dimensions, category, or bullet points.
Barcode Reuse – Using a UPC already linked to another ASIN can cause rejection.
Restricted Category Attempt – Check category permissions before submitting.
