Free GTIN Lookup
Enter any GTIN above to check what it belongs to. 10 free lookups a day.
Free daily lookups · UPC, EAN, GTIN, ISBN & ASIN · 1.6B+ products
A GTIN lookup checks any Global Trade Item Number and shows you the product registered to it: name, brand, images, and the matching UPC, EAN, and Amazon ASIN. It accepts all four GTIN lengths, 8, 12, 13, and 14 digits, and validates the number as it searches. The first 10 lookups each day are free.
TL;DR
- •GTIN is the family name for the GS1 product codes: your UPC and EAN are both GTINs.
- •Google and Amazon ask for a GTIN when you list products. The code on your packaging is the answer.
- •This lookup validates the number and returns the product behind it in one step.
- •Four lengths exist: 8 for small packs, 12 for UPC, 13 for EAN, 14 for cases.
What is a GTIN?
GTIN stands for Global Trade Item Number, the GS1 standard that covers every retail product code. It is not a separate code you need to go and get: the 12-digit UPC on a US product is a GTIN-12, the 13-digit EAN on a European product is a GTIN-13, small packs carry a GTIN-8, and shipping cases carry a GTIN-14. When a platform asks for your GTIN, it is asking for the barcode number your product already has.
How to look up a GTIN
Step 1. Take the number from under the barcode, or from the marketplace form rejecting your listing.
Step 2. Enter it above, any length from 8 to 14 digits.
Step 3. Read the result: whether the number is valid, and the product, brand, and identifiers registered to it.

Why platforms keep asking for your GTIN
Google Merchant Center requires a GTIN for most new products that have one assigned, and listings without it lose eligibility. Amazon asks for a product ID, meaning a GTIN, when you create a listing. Both platforms use the code to match your product to their catalog, which is why a wrong GTIN is worse than a missing one: it attaches your listing to somebody else’s product. Our guides to Google Shopping GTIN requirements and GTIN lookup by API cover both platforms in depth.
What about Amazon GTIN exemptions?
Some products genuinely have no GTIN: handmade goods, generic unbranded items, and certain categories. Amazon handles this with a GTIN exemption you apply for inside Seller Central, and Google handles it with the identifier_exists attribute. The wrong answer is inventing a code or borrowing one from a similar product, marketplaces check codes against the GS1 registry and mismatches get listings suppressed.
GTIN vs UPC vs EAN, once and for all
People meet these three names in the same week and assume three systems. It is one system. GTIN is the family, UPC is the 12-digit member, EAN is the 13-digit member. The GTIN vs UPC page settles the question with a side-by-side table if a colleague needs convincing.
Validating a GTIN
Every GTIN ends in a check digit computed from the other digits, so a single typo makes the number invalid. This lookup runs that math automatically and tells you when a number cannot be real. For the algorithm itself, including how to compute check digits in your own system, see our guide to GTIN validation algorithms.
Bulk checks and the API
Catalogs get checked in one pass through the bulk barcode lookup, upload the CSV and download validated, matched records. Systems use the product data API, which accepts any GTIN length and returns the full record as JSON. The free sandbox covers 10 calls a day (pricing current as of August 2026).

Frequently Asked Questions
What is the full form of GTIN?
GTIN stands for Global Trade Item Number. It is the GS1 family name covering the UPC (GTIN-12), the EAN (GTIN-13), the small-pack EAN-8 (GTIN-8), and the case-level GTIN-14.
Is a GTIN the same as a UPC?
Every UPC is a GTIN, but not every GTIN is a UPC. UPC is the 12-digit member of the family. If a form asks for a GTIN and you have a UPC or EAN, enter that.
Where do I find my product’s GTIN?
Under the barcode on the packaging. The printed digits are the GTIN. If your product has no barcode because you never licensed one, you get GTINs through GS1, not from a lookup site.
Do I need a GTIN to sell on Google Shopping?
For most new products that have one assigned, yes. Google Merchant Center requires it, and products without it lose Shopping eligibility. Genuinely code-less products declare identifier_exists false instead.
What is a GTIN exemption on Amazon?
Permission to create a listing without a GTIN, used for handmade, generic, or code-less products. You apply inside Seller Central. Inventing or borrowing a code instead risks listing suppression.
How is a GTIN validated?
By its final check digit, which is computed from the other digits. One wrong digit breaks the math, which is how typos are caught at scan time and by this lookup.
