EAN vs UPC vs GTIN: What Is the Difference? A Complete Guide
EAN vs UPC vs GTIN: What Is the Difference? 🔢🏷️
When you start selling products online, in retail stores, or through distributors, you will quickly encounter terms such as EAN, UPC, GTIN and barcode.
These terms are closely connected, but they do not mean exactly the same thing.
Understanding the difference can help manufacturers, retailers, distributors, e-commerce sellers and small businesses choose the right product identification approach.
📌 Quick Answer
- GTIN = the broader family of Global Trade Item Numbers.
- UPC-A = a 12-digit GTIN, commonly called GTIN-12.
- EAN-13 = a 13-digit GTIN, commonly called GTIN-13.
- Barcode = a machine-readable graphical representation of information such as a GTIN.
- 91iD™ = an independent product identification and verification system with its own identification architecture.
In simple terms:
GTIN is the identification number family. UPC and EAN-13 are specific GTIN formats. A barcode is the scannable representation of encoded information.
🧩 What Is GTIN?
🌍 GTIN = Global Trade Item Number
GTIN stands for Global Trade Item Number.
It is a globally recognized identification system used to identify trade items that may be priced, ordered or invoiced within a supply chain.
GTIN is not just one number format. It includes several formats depending on the application.
🔢 Common GTIN Formats
| GTIN Format | Common Name | Digits |
|---|---|---|
| GTIN-8 | EAN-8 | 8 |
| GTIN-12 | UPC-A | 12 |
| GTIN-13 | EAN-13 | 13 |
| GTIN-14 | GTIN-14 | 14 |
So when someone says GTIN, they may be referring to one of several standardized GTIN formats.
🏷️ What Is EAN?
🇪🇺 EAN-13 = GTIN-13
EAN commonly refers to the European Article Number, particularly the EAN-13 barcode.
In current GS1 terminology, EAN-13 corresponds to GTIN-13.
EAN-13 contains 13 digits, with the final digit being a check digit.
🔍 Where Is EAN-13 Used?
EAN-13 is widely encountered in:
- 🛒 Retail products
- 🏪 Supermarkets
- 📦 Product packaging
- 🚚 Distribution
- 🌐 E-commerce
- 🏭 Manufacturing
EAN-13 is commonly seen on consumer products in India and many international markets.
🇺🇸 What Is UPC?
🔢 UPC = Universal Product Code
UPC commonly refers to UPC-A, which is a 12-digit GTIN-12.
UPC is traditionally associated with retail products in the United States and Canada.
Like EAN-13, UPC-A is designed to provide a unique identifier that can be represented in a machine-readable barcode.
🛒 Where Is UPC Commonly Used?
UPC can be found in:
- 🇺🇸 United States retail
- 🇨🇦 Canadian retail
- 🛍️ Consumer products
- 🧾 Point-of-sale systems
- 🌐 E-commerce systems
⚖️ EAN vs UPC: What’s the Difference?
🔢 1. Number of Digits
EAN-13: 13 digits
UPC-A: 12 digits
This is the most obvious difference between the two formats.
🌎 2. Common Market Association
UPC-A is traditionally associated with North American retail.
EAN-13 is widely used internationally, including in many Asian and European markets.
However, modern retail and e-commerce systems may support multiple product identification formats.
🏪 3. Product Identification
Both EAN-13 and UPC-A can be used to identify products in retail and supply-chain environments.
The important consideration is whether the identifier meets the requirements of the specific marketplace, retailer, distributor or trading partner.
🧠 GTIN vs EAN vs UPC
💡 Think of Them as a Family
The relationship becomes easier to understand like this:
GTIN
⬇️
GTIN-8 → EAN-8
GTIN-12 → UPC-A
GTIN-13 → EAN-13
GTIN-14 → GTIN-14
Therefore:
EAN and UPC are not completely separate from GTIN. They refer to particular GTIN formats.
🖨️ Is GTIN the Same as a Barcode?
❌ No
This is one of the most common misunderstandings.
A GTIN is a number.
A barcode is a machine-readable graphical representation that can encode that number.
Think of it this way:
Product → GTIN → Barcode → Scanner → Digital System
A scanner reads the barcode and converts the encoded information into data that a computer system can process.
🔍 Simple Example
GTIN: 1234567890123
⬇️
Barcode: ▌▌▍▌▌▍▌▍▌▌▍▌▌
The printed bars are not the GTIN itself. They are the visual representation that allows machines to capture the encoded number.
🧮 What Is a Check Digit?
✅ The Final Digit Helps Validate the Number
Many GTIN formats contain a check digit.
The check digit is calculated using a mathematical algorithm.
Its purpose is to help detect certain data-entry or scanning errors.
It does not normally represent information such as:
- Product name
- Price
- Manufacturer address
- Product description
Instead, it helps validate the identifier.
🛒 Why Product Identification Matters
📦 Inventory Management
Unique product identifiers can help businesses connect physical products with digital inventory records.
🏪 Retail
Retail systems can use product identifiers to distinguish different products and product variants.
🌐 E-commerce
Online marketplaces and e-commerce systems may require product identifiers to associate listings with particular products.
🚚 Supply Chain
Product identification helps businesses communicate about products across manufacturing, distribution, warehousing and retail operations.
🔎 What Is 91iD™?
🆔 Independent Product Identification & Verification
91iD™ is an independent product identification and verification network designed to provide businesses with a structured digital identity for their products.
The 91iD™ numbering architecture is:
91 + 7-Digit Company ID + 3-Digit Product ID + Check Digit
Example:
91 1234567 001 X
Where:
- 91 = 91iD™ prefix
- 1234567 = Company ID
- 001 = Product ID
- X = Check Digit
🌐 What Can 91iD™ Do?
A registered product can have an online identity that can be searched and verified through the 91iD™ platform.
Businesses can use the system to create structured product records and provide customers with a way to access product information.
🔗 Explore 91iD™

⚠️ Important Difference
91iD™ should not be represented as a GS1-issued GTIN.
GS1 GTINs belong to the GS1 identification system, while 91iD™ operates as an independent product identification and verification network.
Businesses should always check the requirements of their marketplace, retailer, distributor or target market before choosing a product identifier.
