What is the difference between ASIN, EAN, and ISBN?

ASIN (Amazon Standard Identification Number) is a unique 10-character alphanumeric identifier assigned by Amazon. EAN (European Article Number) is a 13-digit barcode standard used globally for product identification. ISBN (International Standard Book Number) is a unique numeric identifier for books. Our API converts seamlessly between these formats.

Which Amazon marketplaces are supported for ASIN conversion?

The SellerMagnet ASIN Converter API supports all major Amazon marketplaces worldwide, including US, UK, Germany, France, Italy, Spain, Japan, Canada, Australia, India, Mexico, Brazil, and more. Simply specify the marketplace ID in your API request.

Can I perform bulk ASIN to EAN conversions?

Yes. While each API request handles a single conversion, our infrastructure is designed for high-throughput usage. You can send concurrent requests to convert thousands of identifiers efficiently. Enterprise plans offer elevated rate limits for large-scale operations.

How accurate is the ASIN to EAN conversion?

Our conversion data is sourced directly from Amazon's catalog and updated continuously. The API returns verified EAN and ASIN mappings with over 99.5% accuracy, along with additional product metadata such as title and listing date for validation.

What response data does the converter API return?

The API returns the matched ASIN, a list of associated EANs, the product title, and the date the product was first listed on Amazon. This comprehensive dataset enables thorough product mapping and catalog management workflows.
