Free Barcode Lookup

A barcode lookup is a search that starts from the number printed under a barcode and returns the product it identifies. The bars themselves are just a machine-readable picture of that number. Once you have the digits, a lookup service matches them against a product database and returns the name, brand, images, and other identifiers for the item.

You do not need to know, the search box works it out from the digits. But it helps to recognize what you are holding:

Digits

It is a...

Typical home

12

UPC

Retail products in North America

13

EAN, or a book code starting 978 or 979

Retail outside the US, and books

8

EAN-8 or UPC-E

Small packages like gum and cosmetics

14

GTIN-14

Cases and cartons in warehouses

10 characters with letters

If your code has 12 digits and you want the fastest route, the dedicated UPC lookup is tuned for exactly that. Books go to the ISBN lookup, and European codes to the EAN lookup. All of them share this database.

Step 1. Read the digits printed under the bars. That number is the code, the bars are only its picture.

Step 2. Type the number into the search box above.

Step 3. Review the record: product name, brand, images, category, and the full identifier set.

Step 4. No number to type? Search the product name or brand in the same box.

Usually not. This page works on any phone browser, so the fastest path is: read the digits, type them here, done. If you scan all day on Amazon, install the Chrome extension instead, it shows the UPC, EAN, and ASIN directly on the product page as you browse. Camera-based scanner apps make sense at a warehouse bench, and any of them can pass the scanned number to our API for the product data behind it. Our roundup of barcode scanner APIs for mobile apps covers that setup.

Why it matters

Confirm the exact item and catch look-alikes.

UPC, EAN, GTIN, and ASIN cross-referenced in one record.

Sizing, dimensions, and category placement where available.

Variations, buy box price, and sales rank on paid plans.

Two different questions hide here. Is the number valid? The check digit answers that, a mistyped code fails the math instantly. Is the product genuine? A lookup helps by showing what the code is registered to: if the box says one thing and the record says another, treat it as a warning sign. For brand-level verification, GS1 runs the official registry of who licensed which prefix. Our guide to checking barcode numbers online walks through both checks step by step.

Shipping labels, coupons, and loyalty cards carry barcodes too, and none of them identify a retail product. Code 128 strings on shipping labels encode tracking data, QR codes usually encode a web address, and warehouse labels encode locations and licence plates. A product lookup only makes sense for GS1 retail codes: the 12-digit UPC, the 8 and 13 digit EANs, and the 14-digit case code. If your scan produces letters, a URL, or a 20-plus digit string, you are holding logistics data, not a product identity.

Amazon matching: every result links the barcode to its ASIN, or convert directly with the UPC to ASIN converter.

Retail arbitrage: check a shelf product against its Amazon listing from your phone in seconds.

Catalogs: fix thin product data by pulling names, brands, and images onto your own records.

Every retail barcode follows the same anatomy: a company prefix licensed from GS1, an item number the brand assigned, and a closing check digit that validates the whole string. That is why the lookup can be so confident: it is not searching text, it is resolving a globally unique number to the one product registered against it. It is also why two different products never legitimately share a full code, and why a mismatch between the scan result and the physical item is always worth investigating.

A returns pallet with 40 unlabeled boxes: type each barcode, identify every unit, and price the lot in under an hour.

A marketplace form demanding a GTIN: look up your own product by name, copy the code from the record, done.

A suspiciously cheap branded item: check what the code is registered to. If the record and the product disagree, walk away.

Everything on this page is one API call: send any identifier, get the full record as JSON. The product data API page covers fields and pricing, and the free sandbox includes 10 calls a day against the complete database, no card needed.
