Free UPC Lookup

UPC stands for Universal Product Code. It is the 12-digit number under the barcode on most products sold in North America. Brands license their codes through GS1, the not-for-profit body that runs the global barcode system, so each sellable product has its own unique UPC. The last digit is a check digit that catches typing mistakes.

Step 1. Find the 12 digits printed under the barcode, usually on the back or bottom of the packaging.

Step 2. Type them into the search box at the top of this page. No signup is needed.

Step 3. Read the result: product name, brand, images, category, and every linked identifier.

Step 4. Need the Amazon side? The record shows the matching ASIN, and one click takes you to the listing.

Typed 12 digits and got nothing? Check the number again first, one wrong digit breaks the check digit math. If the code is right and still misses, the item may be store-brand or very new. Try searching the product name instead, the same box handles both.

Every result is built from our index of more than 1.6 billion products (EcomSource platform data, August 2026). A single lookup returns:

On the packaging, under the barcode. Look on the back or the bottom of the box, near the fine print. The 12 digits printed beneath the black bars are the UPC. On books you will see an ISBN instead, and on many imported products a 13-digit EAN. All three work in the search box above, and the barcode lookup page handles every format if you are not sure what you have.

The same GS1 system covers every retail barcode format you will meet in sourcing:

This is the workflow the tool was built around. A supplier quotes you a pallet with a UPC list. Before you commit money, you need to know what each code is on Amazon: which ASIN, which variation, who holds the buy box, and what the sales rank looks like. Run the UPCs here, or convert them directly with the UPC to ASIN converter. Working from an Amazon listing back to the barcode? That is the ASIN to UPC converter.

Checking codes while you browse Amazon? The Chrome extension shows the UPC and EAN on the product page itself, and our guide to Amazon Brand Registry UPC requirements explains why brands must keep these codes consistent.

Nearly two thousand people a month search for a Walmart UPC lookup specifically, and the answer is simpler than it sounds: a UPC is the same code everywhere. The number on a product at Walmart is the number on that product at Target and on Amazon, because all of them read the same GS1 code from the packaging. So any UPC from any retailer works in the search box above, and the record it returns includes the Amazon listing for cross-checking prices. What differs per retailer is their internal item number, which is a SKU, not a UPC, and lives on the shelf label rather than the product.

Paste-one-at-a-time stops making sense around ten codes. Upload a CSV to the bulk barcode lookup and get the whole list matched in one pass. Developers can do the same through the product data API, which returns each record as clean JSON. The free plan covers 10 lookups a day, Starter covers 3,000 a month for $10, and Pro covers 10,000 for $49 (pricing current as of August 2026).

The 12 digits are not random. The first digits are the company prefix that GS1 licensed to the brand, the middle digits are the item number the brand assigned, and the final digit is the check digit. Two practical consequences follow. Products from the same brand share a prefix, which is why a supplier list from one manufacturer looks so uniform. And no legitimate product shares its full code with another, so if a scan brings up something different from the box in your hand, the listing data is wrong or the label is, and both are worth knowing before you buy or sell that item.

Typing the ISBN of a book into a UPC field. Books use their own system, run them through the ISBN tool instead.

Reading the small numbers at the far left and right edges of the bars as part of the code. The UPC is the 12 digits printed together under the center.

Assuming a case code is the unit code. Cartons carry 14-digit codes that wrap the product UPC, scan the retail unit inside for the 12-digit version.

Treating a miss as proof the product is fake. Missing usually means store-brand, regional, or new. Verify with a name search before concluding anything.

Records are matched by identifier against an index of more than 1.6 billion products (EcomSource platform data, August 2026).

Every result cross-references the UPC with its EAN, GTIN, and ASIN, so you see one product, all codes.

The same data is served to our API customers, so the free tool is not a watered-down version.
