ASIN

ASIN (Amazon Standard Identification Number) is a unique identifier assigned by Amazon to every product listed on its marketplace. It helps Amazon and sellers track, manage, and monitor products efficiently.

What is an ASIN?

ASIN stands for Amazon Standard Identification Number. It is a unique 10-character alphanumeric code assigned to each product listed on Amazon. ASINs allow Amazon to organize products in its catalog and help sellers, tools, and systems reference the exact product without confusion.

Why ASINs Are Important for Sellers

  • Ensures accurate product identification across marketplaces
  • Required for advertising, inventory management, and reporting
  • Used to monitor competitors selling the same product
  • Essential for price tracking, Buy Box analysis, and alerts
  • Prevents listing confusion between similar products

Where Can You Find an ASIN?

An ASIN can be found on the product detail page under the product information section or directly in the product page URL. For sellers, ASINs are also visible in Seller Central reports and inventory listings.
