How to Use the Amazon Seller App to Scan Products

1. What Is the Amazon Seller App Scanner

The Amazon Seller App scanner is a built-in barcode scanner inside Amazon's free seller app. Point your phone camera at any product barcode and the app pulls up the live listing, BSR, Buy Box price, active offers, and an FBA profit estimate in about 5 seconds.

Almost every retail arbitrage seller starts here. I used it on my first trip to Target before I knew what Keepa was. You need your phone and a store, nothing else.

If you're still getting your bearings with the overall FBA model, start with the complete guide to starting Amazon FBA first. This article assumes you have a Seller Central account and you're ready to go look at products.

2. How to Download and Set Up the App

Search "Amazon Seller" in the App Store or Google Play, sign in with your Seller Central credentials, and you're done. It's free.

Once you're in, tap the camera icon in the top-right corner of the home screen. Grant camera permission when the app asks, and you're ready to scan.

Make sure your seller account is fully verified before you check live data. Accounts in a verification hold show limited info. If you're still working through account setup, the Amazon seller account setup guide walks through every step including identity verification.

3. How to Scan a Product Barcode

Point the camera at the barcode on the bottom or back of the product. The app focuses and pulls the listing in under 5 seconds on a solid cell connection, no tapping required.

If the barcode won't read because of a damaged label or bad angle, tap the keyboard icon in the scanner and type the ASIN or UPC manually. That gets you the listing every time.

Some clearance tags at Target and Walmart have QR codes on them. The app scans those too. Not every store uses them, but when they're there, they're faster than hunting for the barcode.

If your scan lands on a variation parent instead of the exact product, the page shows a list of child variations. Tap the one that matches the color, size, and style you're holding. The wrong variation gives you wrong BSR, wrong price, and wrong margin.

4. Reading the Product Data Page

The product page shows:

• Sales Rank (BSR): listed under the category name. Lower number means more sales.
• Buy Box price: what a buyer pays right now.
• Number of offers: total active sellers on the listing in new condition.
• FBA vs. FBM: whether the Buy Box winner ships from Amazon's warehouse or directly from a seller.
• Amazon on listing: whether Amazon itself is one of the sellers competing for the Buy Box.

Scroll down and you'll also see the product title, ASIN, and a "Calculate" button that opens the revenue estimator. That button is where you'll spend most of your time.

The fees feeding into that calculator include the referral fee (a percentage of sale price, set by category) and the FBA fulfillment fee (based on size and weight). The Amazon FBA fees breakdown explains every line item if you want to understand exactly what you're paying before you buy a single unit.

5. BSR and What It Actually Means

BSR ranks a product within its category. A BSR of 500 in Kitchen means that item outsells 499 other Kitchen products on Amazon right now. Lower number, higher sales velocity.

The raw number only makes sense relative to the category size. A BSR of 50,000 in Toys might mean 20 sales a day. A BSR of 50,000 in Automotive might mean 2. Different categories have different total product counts.

In most main categories, anything under 100,000 BSR is moving product. Under 50,000 is solid for OA and retail arbitrage. The full BSR guide for online arbitrage gives category-by-category benchmarks if you want specific cutoffs.

The BSR the app shows is a live snapshot. The rank could be temporarily spiking from a burst of orders, or sitting high because it sold out last week. The app alone won't tell you which.

6. The Built-In Revenue Calculator

Tap "Calculate" from the product page. Enter your cost (what you'd pay at the store) in the "Item Price" field. The app calculates your estimated net payout after Amazon's referral fee and FBA fulfillment fee.

It won't factor in your inbound shipping cost or prep center fees. Add those manually. I subtract $0.50 to $1.50 per unit for those costs depending on item size and whether I'm using a prep center.

My minimum thresholds: 30% ROI and at least $3.00 net after everything. If the calculator shows a $1.50 net on a $12 buy price, I skip it. Price drops and new competitors kill thin margins. The Amazon ROI formula guide shows exactly how to run this math so nothing gets missed.

7. The Offers Tab: Reading Your Competition

Tap the "Offers" tab on the product page to see every active seller, their price, condition, and whether they're FBA or FBM. That tab shows how competitive the listing is right now.

Count the FBA sellers specifically. With 15 FBA sellers on a listing and a BSR of 80,000, the Buy Box rotates across all 15. That BSR might mean 30 sales a month total, or 2 units per seller per month. Buy 10 units at that ratio and you're sitting on slow inventory.

The setup I look for: 3 to 5 FBA sellers, no Amazon on the listing, Buy Box price high enough that I can match it and hit my margin. That competitive environment means a new unit sells within a reasonable window.

Also check whether FBA sellers are clustered at the same price or spread out. A tight cluster at $24.99 means repricers are competing. A spread from $22 to $31 usually means one seller is holding a higher price while others are lower. Price at or just below the FBA cluster to get Buy Box rotation.

8. What the App Won't Show You

The app gives you a snapshot of right now. It won't show what the Buy Box price was 90 days ago, whether that BSR is stable or spiking, or how many sellers were on the listing last month. That missing context is where buying mistakes happen.

"If you buy something on Walmart.com that you found doing a Tactical Arbitrage scan... the chance that a lot of other sellers found the same product is pretty high. If you find a lead that way, it's pretty sure that a lot of sellers are going to jump on it." 5 Common Sourcing Mistakes New Amazon FBA Online Arbitrage Sellers Make

The same logic applies to anything sourced from a heavily scanned channel. The app shows current state. Thirty other sellers may have run the same scan you ran, and you won't see them coming.

Keepa fills those gaps. Check the price and BSR history before you commit to a buy. The Keepa Chrome extension tutorial walks through reading those charts. And if you want a single tool that combines Keepa data with full profit analysis, the SellerAmp review covers what it does and what it costs.

9. FNSKU Labels: The 2026 Reality for Every Seller

Amazon ended commingling on March 31, 2026. Every reseller, including every retail and online arbitrage seller, puts an FNSKU label on every unit in every category. If you're not the Brand Representative in Brand Registry, you label your units.

Amazon stopped its prep and labeling service on January 1, 2026. Print labels from Seller Central yourself or send inventory to a prep center that handles it.

When you scan a product and decide to buy it, plan for labeling before it ships to FBA. A unit arriving at a fulfillment center without a required FNSKU barcode counts as an inbound defect and loses reimbursement eligibility. The FNSKU label printing guide covers the full process from generating labels in Seller Central to applying them correctly.

If you're still working through what the commingling changes mean for your sourcing decisions, the commingled vs. sticker FBA breakdown explains what changed and why it matters for every arbitrage seller.

10. My Actual Process on a Retail Arbitrage Run

I walk clearance sections first, scan the barcode, and check BSR. If it's over 500,000 in a main category, I move on without opening the calculator. That single filter kills about 70% of scans in under 3 seconds.

If BSR clears, I check the offers tab. More than 6 FBA sellers with Amazon on the listing, I skip it. Under 5 FBA sellers and no Amazon, I open the calculator, enter my cost, and check for 30% ROI and $3.00+ net.

The whole check takes 20 to 30 seconds per item. Most products fail fast. I'm looking for the 1 in 15 that passes all three filters: BSR, competition, and margin.

Walmart clearance endcaps are the most consistent source for this. The Walmart retail arbitrage guide covers which sections to hit and what days clearance markdowns happen. If you want to watch me run a real sourcing session live, grab a free seat at my Thursday training where I do exactly this on camera.

11. When to Graduate Past the App

The Amazon Seller App scanner is the right starting tool. It teaches you what data matters: BSR, competition count, and margin. Use it until those three checks feel automatic on every scan.

Once you're running 50+ product checks per day or buying in volume, the app slows you down. It has no Keepa integration, no batch scanning, and no way to filter hundreds of products at once. Every serious OA seller I know has moved to dedicated sourcing software.

12. Next Steps

If you've never used the scanner, go run 20 scans this week. Walk a Walmart or Target clearance section and apply the three-filter check: BSR, competition, margin. The repetition builds pattern recognition faster than reading about it.
