Frequently Asked Questions

Q: How many ASINs can I convert at once?

A: Rocket Source can support even the most demanding needs. Our Scale plan is capable of running lists of hundreds of thousands of products without skipping a beat. However, free plans are limited to just one scan of up to 50k ASINs per week.

Q: What Amazon marketplaces do you support?

A: All of them! We support all Amazon marketplaces including US, CA, MX, UK, DE, FR, IT, ES, NL, SE, PL, AU, JP, SG, AE, SA, IN, TR, EG, and BR.

Q: What data points does Rocket Source provide?

A: We provide 90+ data points including the converted UPC/EAN, pricing information, BSR (Best Seller Rank), competitor data, FBA fees, and profitability calculations.

Q: Why would I need to convert ASIN to UPC?

A: Common use cases include: listing products on other marketplaces like eBay or Walmart that require barcodes, verifying product authenticity, cross-referencing with supplier catalogs, and scanning products in retail stores for arbitrage opportunities.

Q: What if an ASIN doesn't have a UPC?

A: Some products on Amazon don't have associated UPC/EAN codes, particularly Amazon-exclusive products, handmade items, or listings created with GTIN exemptions. In these cases, we'll indicate no match was found.

Q: What's the difference between UPC and EAN?

A: UPC (Universal Product Code) is a 12-digit barcode primarily used in North America, while EAN (European Article Number) is a 13-digit barcode used internationally. Many products have both, and our converter returns all available identifiers.
