ASIN to EAN: The Secret to Finding Wholesale Suppliers for Amazon Products
If you’ve ever spotted a fast-moving product on Amazon but couldn’t buy it because you didn’t know the supplier, this guide is for you. The key is converting the Amazon ASIN into the EAN (and often the UPC)—the barcodes suppliers and distributors actually use. Below I’ll show you two ways to get those barcodes (free and bulk), how to use them to find real suppliers, and the exact outreach template and follow-up process to turn those leads into wholesale accounts.
Quick definitions
ASIN: Amazon’s internal 10-character product identifier.
EAN / UPC: Global retail barcodes used by brands, distributors, and wholesalers in their systems and catalogs.
Why this matters: suppliers think in EAN/UPC, not ASIN. Convert first—then search and outreach.
Step 1: Convert ASIN → EAN/UPC
Option A (Free & fast for one-offs)
Use the free ASIN to EAN/UPC Converter:
➡️ https://www.analyzer.tools/asin-to-upc-ean-converter/
Paste an ASIN, click Convert.
You’ll often get both EAN and UPC. Keep both—different suppliers index one or the other.
Option B (Bulk + risk checks)
Use Analyzer.Tools to process a whole list at once and pre-screen for risk:
➡️ https://www.analyzer.tools/
Upload your ASIN list.
Pull back EAN/UPC, brand, estimated sales, and flags for IP complaints and brand restrictions—before you waste time on risky lines.
Pro tip: In Analyzer.Tools results, add the ASIN, EAN, UPC, Brand, Sales, and IP/Restriction columns. Filter out slow movers and anything with IP/red flags before sourcing.
Step 2: Find suppliers who actually sell the item
You’ve got the EANs. Now you need suppliers. Use both methods below.
Method 1: Go top-down via the brand
Identify the brand (visible in Analyzer.Tools or the Amazon listing).
Email or call the brand: ask for their authorized distributors for your region.
Contact those distributors. Mention:
You were referred by the brand (include the rep’s name if you have it).
The exact products (name + EAN) and estimated monthly units you want.
If a distributor won’t sell to you (you’re too small or don’t meet criteria), ask:
“Who do you supply that could sell this to us? Could you introduce or point us to them?”
This moves you down the supply chain to someone who will transact.
Method 2: Use EANs to search the open web (and scale it)
Google the EAN directly—many supplier and retailer pages list EANs in text or images.
For speed, put all EANs in a Google Sheet and use an AI assistant to find supplier pages, emails, and phone numbers at scale.
Starter prompt (paste into your AI with your EAN list):
You are a sourcing research assistant. I will give you a list of product EANs.For each EAN, find supplier candidates (wholesalers, distributors, or retailers who carry the exact barcode).Return a table with: EAN, Supplier Name, Supplier Type (Distributor/Wholesaler/Retailer), Product Page URL, Contact Email, Phone, Notes (e.g., MOQ, region).Prioritize B2B sources first. Only include pages where the exact EAN appears on the page (text or image/alt text).Step 3: Outreach that gets replies (email template inside)
Two keys:
Lead with buying intent, not “opening an account.”
Show a meaningful order value (ideally >$2,000–$5,000 combined) so it’s worth their time.
Copy-paste email template
Subject: Product Enquiry – {Product Name} – {Units Required} Hi {Supplier Name}, We are looking for the following product(s): - {Brand} {Product Name} — EAN: {EAN} — Qty: {Estimated monthly sales or your target units}- {Add additional lines as needed to reach a combined order value > $2,000–$5,000} Could you please confirm if these items are ones you can supply? If so, please let me know:• Pricing• Availability (current stock and lead times) We’re ready to move quickly and purchase within the next few days. If I don’t hear back, I’ll follow up with a phone call. Kind regards,{Your Name}{Company}{Phone}Why this works: it’s short, specific, and focused on revenue today. Busy reps care about clear demand, not your company history.
3–4 day follow-up (call script)
“Hi, I emailed a few days ago about purchasing {Product Name, EAN, Qty}. Are you able to supply and share pricing? We’re looking to place an order this week.”
Don’t ask to “open an account.” If they’ll sell to you, the account process follows.
Step 4: Turn quotes into purchase orders (fast)
When a supplier replies—good price or not—always ask:
“Thanks for the pricing. Could you also share a full price list or current stock list?”
Then analyze that list at scale:
Upload price lists to Analyzer.Tools (map barcode column to EAN/UPC, add cost price, optional title/SKU).
Sort by profit, check sales velocity, open Keepa charts from the results, and shortlist winners.
Build an order from the best combos of profit + velocity + risk-free (no IP issues).

Bulk + risk screen: https://www.analyzer.tools/
Filter out IP/restricted/slow products.
Find suppliers
Brand → distributor(s) → downstream.
Google EANs and scale with AI research.
Outreach with the template (combine lines to exceed $2k–$5k value).
Follow up by phone in 3–4 days.
Request full price lists from anyone who replies.
Analyze lists in bulk with Analyzer.Tools; pick winners.
Place orders, then repeat the cycle.
FAQs
What if the converter returns only UPC (no EAN)?
Keep it. Some suppliers index by UPC. Search with UPC and EAN variants.
Do I need brand approval on Amazon first?
You don’t need it to source suppliers, but you must be compliant to sell. Use Analyzer.Tools’ brand/IP checks early to avoid bad leads.
How big should my initial ask be?
Aim for >$2,000–$5,000 combined across lines. Small “test” asks often get ignored.
What if a distributor denies me?
Ask who they supply that could sell to you. Name-drop the referring contact when you reach out.

Final thoughts
Winning wholesale accounts starts with speaking the supplier’s language—EAN/UPC—then doing targeted, value-led outreach. Combine a clean pre-screen (IP, brand restrictions, sales) with persistent follow-up and fast list analysis, and you’ll turn Amazon “wish-list” products into real, profitable purchase orders.
