ASIN and EAN are the codes that identify every product on Amazon: understanding them helps you compare prices across marketplaces and find real deals.
Navigating Amazon deals can feel like a maze: same product, different prices, different marketplaces. The key to not getting lost are two codes: ASIN and EAN. Understanding what ASIN and EAN mean on Amazon gives you a superpower: comparing the same item across the six Glitchoo stores (Italy, UK, Germany, Spain, France, USA) and spotting price differences or real errors. In this practical glossary, we break down what they are, where to find them, and how to use them to become a smarter deal hunter.
What does ASIN mean on Amazon
ASIN stands for Amazon Standard Identification Number. Think of it as the ID card for a product on Amazon: it's a unique alphanumeric code (usually 10 characters) that Amazon assigns to every variant. Each color, size, or model gets its own ASIN. If you search for a specific appliance on Amazon US and the same exact model on Amazon UK, the ASIN will likely be different, even though the product is physically the same. Why? Because the ASIN is tied to Amazon's local catalog.
How to find a product's ASIN
It's easy: on the product page, scroll down to the "Product Details" section. Or look at the URL: after /dp/ you'll find the ASIN. For example, in amazon.com/dp/B0ABCDEFGH, the B0ABCDEFGH part is the ASIN. You'll also find it in the technical specs, and on Glitchoo, every deal card shows the code.
Why ASIN matters for deal hunters
On Glitchoo, we monitor over 35,000 products in real time. The ASIN allows us to track the same variant on one store and compare its 90-day price history. If you see a list price that looks like a 60% discount, our Trust Score uses the ASIN to verify whether that discount is real compared to the history. If a product has multiple ASINs (say, for different colors), the discount can vary: keep an eye on all ASINs of a model to catch the best glitch.
What does EAN mean and how it differs from ASIN
EAN (European Article Number, now often GTIN or ISBN for books) is a universal 13-digit code that identifies the physical product globally. Unlike ASIN, the EAN is the same across all marketplaces: Amazon, eBay, physical stores. If you buy a pair of headphones with EAN 1234567890123, you'll find the same EAN on Amazon Germany and Amazon USA, even though the ASIN is different.
EAN vs ASIN: comparison table
| Feature | ASIN | EAN |
|---|---|---|
| Where used | Amazon only | Universal (all marketplaces) |
| Format | 10 alphanumeric characters | 13 digits (or 12 UPC, 13 EAN) |
| Uniqueness | Unique per variant and store | Same product has same EAN everywhere |
| Utility for glitches | Compare history on one store | Compare prices across stores |
Where to find EAN on Amazon
Scroll the product page to "Product Details": it's often listed as "EAN" or "ISBN". If it doesn't appear, look for the barcode on the product packaging (if you have it physically). On Glitchoo, we include the EAN in deal cards when available, so you can copy it and paste it into other stores.
Using codes to spot price errors
Here's the key point: combining ASIN and EAN gives you surgical precision. Let's say you find on Amazon US a pair of Bluetooth headphones for $19.99 with a 70% discount. The ASIN is B0CXXXXX1. You copy the EAN from the page (e.g., 1234567890123) and paste it into Amazon UK: the same model has a regular price of £59.99. Is the US discount an error? Glitchoo's price history shows the average price was $49.99, so the 70% is real. But if on UK the price is £14.99, the discount might be inflated.
Keep in mind that prices change constantly: always verify on the Amazon product page before buying. Glitchoo does the heavy lifting for you: our database scans 35,630 products and right now we have 752 active price errors, with an average discount of 66.8% compared to 29.4% for normal promotions. Use the ASIN to see the history, the EAN to compare across stores.

Real-world examples today
To give you an idea, today we're featuring:
- Bluetooth 5.4 headphones (US): 85% off on Amazon US. The ASIN is specific to color — black and white have different codes: check both, because one color might be glitched and the other not.
- Tommy Hilfiger Chino (Spain): -83% on clothing. The model's EAN is the same on Amazon Germany and France; compare to see if the Spanish price is truly the lowest.
These deals are in the section below: click on the cards to go directly to the product page and verify yourself with Glitchoo's tools.
Frequently asked questions
Is ASIN the same across all Amazon countries?
No, the ASIN is specific to each marketplace. The same physical product has a different ASIN on Amazon.com and Amazon.co.uk. The EAN is global.
How do I find the EAN if it's not on the page?
Try looking at the barcode on the packaging, or use third-party GTIN databases. On Glitchoo, we publish the EAN when available.
Can I use ASIN to find a product on eBay?
No, ASIN is Amazon only. Use the EAN or the manufacturer's product code on other marketplaces.
Does Amazon always honor a price error?
No. Amazon may cancel the order if the error is obvious (e.g., $1 for a TV). Glitchoo does not encourage techniques to force honor — we only explain how to recognize a glitch. Check Amazon's conditions.
How does Glitchoo use ASIN and EAN for the Trust Score?
The Trust Score compares the current price with the 90-day history of the same ASIN (same store). If the discount is real, the score is high. The EAN is used for cross-store comparisons but does not affect the score.
Conclusion
Now that you know what ASIN and EAN mean on Amazon, you have the tools to avoid being fooled by inflated discounts and to find real price errors. Next time you see a deal, use these codes to verify: don't trust the list price — check the history. Glitchoo already does it for you, but understanding the mechanics makes you a smarter shopper.
