¿Qué es el conversor de UPC a ASIN?

El conversor de UPC a ASIN de Seller Assistant convierte al instante los códigos UPC o EAN en ASIN de Amazon. Ayuda a los vendedores de Amazon a vincular con precisión los productos de los proveedores con los listados de Amazon.

What is a UPC?

UPC (Universal Product Code) is a 12-digit barcode standard used globally to identify retail products. Manufacturers assign UPCs to products, and Amazon sellers use them to match supplier items with Amazon's catalog. A single UPC can sometimes correspond to multiple ASINs due to variations, multipacks, or different conditions.

Why does one UPC return multiple ASINs?

A single UPC can match multiple ASINs because Amazon creates separate listings for product variations like pack sizes (5-pack, 10-pack), bundles, different conditions (new, used), or marketplace variations (Amazon.com vs Amazon.ca). Seller Assistant's converter identifies all matching ASINs so you can choose the correct one for your sourcing.
