The Sellers Index storefront scan (January–February 2026) covers 38,088 storefronts on Amazon.com — the largest single marketplace in the dataset. Of those, 72.1% originate from China (27,462 storefronts) and 19.8% are US-based (~7,545 storefronts), with the remaining 8.1% spread across GB, and other origins. The average storefront rating across Amazon.com is 4.68 — the highest of any scraped marketplace in the dataset. US-origin sellers average 305 reviews per storefront; China-origin sellers average 98. Alongside the storefront scrape, TSI's enriched leads_master dataset contains 4,840 USA-marketplace records, every one carrying a verified email address, a VAT number, and a business summary — the actionable layer for compliant B2B outreach. This is a storefront-level scrape, not a registry-verified census of all Amazon.com sellers.

USA Amazon Seller Data: 38,088 Storefronts Tracked on Amazon.com (Jan–Feb 2026)
The Sellers Index storefront scan covers 38,088 Amazon.com storefronts — the largest marketplace in the dataset. 72.1% of those storefronts originate from China (27,462), while US-based sellers account for 19.8% (~7,545). The average storefront rating is 4.68 — the highest of any scraped marketplace. A separately enriched subset of 4,840 USA-marketplace records is available with 100% verified email, VAT, and business summary coverage. Note: this is a storefront-level scrape, not a registry-verified census of all Amazon.com sellers.
The USA dataset is the largest by storefront count in the TSI marketplace scan. The contrast with EU markets is stark: enriched registry-verified datasets for Spain and Italy show majority-local sellers — because EU business registries surface local companies first.

Why Amazon.com Seller Data Matters
Amazon.com is the world's largest Amazon marketplace. At 38,088 tracked storefronts, it dwarfs every European marketplace in the dataset — and its seller-origin structure is fundamentally different.
Unlike EU marketplaces where enriched datasets surface majority-local sellers, the USA storefront scrape reveals a China-dominated marketplace: 72.1% China-origin, 19.8% US-based. That structural reality has direct implications for compliance providers, logistics agencies, and brands seeking to identify true US-based competitors.

Where Our USA Amazon Seller Data Comes From
marketplace scan Storefront Scrape (Jan–Feb 2026)
The primary USA dataset is built from a structured storefront scan of Amazon.com, capturing 38,088 active seller storefronts. This is the broadest signal available at marketplace scale: it captures ratings, review counts, product counts, categories, and — critically — the base country of each seller, revealing the China-dominated structure not visible from surface-level Amazon data.
Enriched leads_master Subset
The actionable layer is TSI's enriched leads_master dataset: 4,840 USA-marketplace records each carrying a verified email address, a VAT number, and a business summary. This subset undergoes SMTP handshake verification for email deliverability and is the recommended starting point for compliant B2B outreach targeting US-marketplace sellers.
The China-Dominated Marketplace
72.1% of tracked Amazon.com storefronts operate from China. That is the defining structural fact of the USA marketplace dataset.
What that means for buyers of this data:
- Compliance providers — identify cross-border sellers needing US tax nexus, product liability, or import compliance
- Logistics & freight — target China-origin sellers shipping to US-based FBA warehouses
- Brands & resellers — filter for the 19.8% of genuinely US-based sellers for competitive or partnership intelligence
Base country data is unique to The Sellers Index. No other USA Amazon seller data provider surfaces operational origin at this resolution.
Example: China-origin storefronts dominate Amazon.com — TSI base country field surfaces this at record level.
What a USA Amazon seller dataset should include
A USA Amazon seller dataset that is fit for commercial use must go beyond a list of storefront names. The structural reality of Amazon.com — where nearly three-quarters of sellers operate from China — means that base country data is not a bonus field; it is the primary segmentation axis.
The TSI dataset carries that field on every record, alongside storefront rating, review count, product category, and — in the enriched verified subset of 4,840 records — a verified email address, VAT number, and business summary. Buyers working in compliance, freight logistics, or competitive intelligence need the full picture, not just the storefront URL.
