How to Check an Amazon Seller Before Buying
A practical guide to verifying seller trust on Amazon — what to check, what to avoid, and how tools can help.
~7 min read
Amazon's marketplace includes millions of third-party sellers. While most are legitimate businesses, the open marketplace also attracts bad actors who list counterfeit products, fail to ship orders, or provide no customer support. Checking the seller before you buy is one of the most effective ways to reduce risk.
Key Takeaways
- Always check who is selling — Amazon, the brand, or a third-party reseller
- Seller age and feedback volume are key trust indicators
- FBA (Fulfilled by Amazon) carries lower risk than FBM (Fulfilled by Merchant)
- Tools like Shopping Trust Guard can automate seller checks on every product page
1. Identify Who Is Actually Selling the Product
On any Amazon product page, look for the “Sold by” information below the Buy button. The seller might be Amazon itself, the brand manufacturer, or a third-party reseller. Products sold and shipped by Amazon generally carry the lowest risk because Amazon handles fulfillment and returns.
2. Check the Seller’s Feedback Rating
Click on the seller name to view their seller profile. Amazon displays a feedback rating percentage based on buyer reviews of the seller’s service. Look for ratings above 95% positive, pay attention to the volume of ratings, and read recent negative feedback to see if there are recurring issues.
3. Look at How Long the Seller Has Been Active
Sellers who have been on Amazon for years with consistent positive feedback are generally more trustworthy than sellers who opened their account recently. New sellers are not necessarily bad, but they represent higher risk because they have no track record.
4. Check the Fulfillment Method
Products fulfilled by Amazon (FBA) are stored in Amazon warehouses and shipped by Amazon. This generally means faster shipping, easier returns, and Amazon’s customer service backing the transaction. Products fulfilled by the seller (FBM) rely on the seller for shipping and returns, which can be riskier.
5. Verify the Seller Is the Brand Owner
If you are buying a branded product, check whether the seller is the brand’s official store. Third-party resellers selling branded products at significantly lower prices may be offering counterfeit or grey-market goods. Look for the brand name in the seller name or check if the listing has a “Brand Store” link.
6. Use a Seller Checker Tool
Manually checking all of these factors for every purchase is time-consuming. Shopping Trust Guard’s Amazon Seller Checker automates this process by analyzing seller data directly on the product page and incorporating it into the overall Trust Score.
7. Cross-Reference with External Sources
For high-value purchases, consider checking the brand or seller outside Amazon: Does the brand have a professional website? Are there reviews or discussions about the seller on Reddit or consumer forums? Does the brand have social media presence with real customer engagement?
Seller Red Flags to Watch For
- Seller account created in the last few months — new sellers with no track record
- No seller feedback or very few ratings — insufficient data to assess trust
- Price significantly below market rate — counterfeits are often priced to sell quickly
- Seller has changed their business name — some bad actors rebrand to escape negative feedback
- No return policy or very restrictive returns — legitimate sellers typically offer standard returns
- Product listing has poor images or generic descriptions — may indicate a low-effort listing
What to Do If You Have a Problem
