details in a way that can simply be decoded. GS1 explicitly notes that the number itself has no such intrinsic meaning without access to a database.
🔗 The Identifier Works as a Database Key
Think of it like this:
GTIN
= 🔑 Key
Product Database
= 🗄️ Information
The key allows the system to retrieve the relevant information.
🌐 Where Does the Product Information Come From?
💻 The connected database
When a barcode is scanned, the connected system determines what information is associated with that identifier.
Depending on the environment, the database may contain:
- 🏷️ Brand
- 📦 Product description
- 🧴 Product category
- ⚖️ Net content
- 🌍 Country of sale
- 🖼️ Product image
- 📋 Additional product information
GS1’s Verified by GS1 service, for example, provides company information and product information associated with GS1 identifiers where available.
🏪 Different Databases Can Contain Different Information
A supermarket’s internal database may contain:
Price + Stock + Product Name
while another product database may contain:
Brand + Product Description + Image
Therefore, scanning the same identifier does not mean every system will display exactly the same information.
📊 EAN-13 Barcode vs Product Database
🔍 The difference
| EAN-13 Barcode | Product Database |
|---|---|
| Machine-readable | Digitally stored information |
| Represents an identifier | Stores product details |
| 13-digit GTIN-13 | Product record |
| Scanned by barcode reader | Queried by software |
| Does not normally contain price | Can contain price |
| Does not normally contain product description | Can contain description |
| Can be printed on packaging | Exists in a digital system |
This distinction is fundamental to understanding how barcode systems work.
🆔 How Does 91iD™ Relate to Product Identification?
🌐 Independent Product Identification & Verification
This is where 91iD™ enters the broader product-identification ecosystem.
91iD™ is an independent product identification and verification network designed to associate a structured identifier with an online product record.
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
🔎 Product Identity
The concept is:
🏭 Company
⬇️
🆔 Company ID
⬇️
📦 Product
⬇️
🔢 Product ID
⬇️
91iD™ Identifier
⬇️
🌐 Online Product Record
This gives a registered product a structured digital identity that can be searched and verified through the 91iD™ platform.
⚠️ Is 91iD™ an EAN-13 or GS1 GTIN?
❌ No
This distinction must remain clear.
EAN-13 / GTIN-13 is part of the GS1 identification system.
91iD™ is an independent product identification and verification system with its own numbering architecture.
Therefore, a 91iD™ identifier should not be represented as a GS1-issued GTIN or EAN-13.
🌱 Different Systems, Different Purposes
A business should check the requirements of its:
- 🛒 Marketplace
- 🏪 Retailer
- 🚚 Distributor
- 🌍 Export market
- 📦 Supply chain
before deciding which identifier it needs.
🔐 Can an EAN-13 Barcode Prove Product Authenticity?
⚠️ Not by itself
Scanning an EAN-13 barcode does not automatically prove that a physical product is genuine.
The barcode primarily provides a machine-readable product identifier.
🔍 Verification Needs a Trusted Record
A verification system can associate an identifier with:
- Company information
- Product information
- Registration status
- Product record
- Other relevant data
This creates a stronger connection between the physical product and its digital identity.

📱 Can a Smartphone Read an EAN-13 Barcode?
📷 Yes, with compatible software
Many modern smartphones and barcode-scanning applications can read EAN-13 symbols.
The camera captures the barcode image and software decodes the pattern.
However, reading a barcode and retrieving product information are two different steps.
The smartphone may decode:
EAN-13 → GTIN-13
but the application still needs access to an appropriate database or service to retrieve product details.
🏪 Where Is EAN-13 Used?
🛒 Retail
EAN-13 is widely used for retail trade-item identification.
📦 Product Packaging
Manufacturers can print EAN-13 symbols on product packaging when the format is appropriate for their identification requirements.
🏬 Supermarkets
Checkout systems can scan EAN-13 symbols and use the decoded identifier to retrieve product records.
🌐 E-commerce
Product identifiers can also be used in online product catalogues and marketplace systems, subject to the specific platform’s requirements.
GS1 identifies EAN-13 and UPC-A among the common barcodes used for retail trade-item identification.
🔢 What Other Information Can GS1 Barcodes Carry?
📦 EAN-13 Has a Specific Role
EAN-13 is primarily used to represent a GTIN-13 for trade-item identification.
Other GS1 barcode technologies can encode additional information.
For example, GS1-128, GS1 DataMatrix and GS1 QR Code can carry a GTIN along with additional attributes such as batch numbers, expiry dates or serial numbers, depending on the application.
💡 This Is an Important Difference
EAN-13
➡️ Primarily retail product identification
Other GS1 data carriers
➡️ Can support richer structured data
So you should not assume that every barcode stores the same amount or type of information.
❓ Frequently Asked Questions
What information is stored in an EAN-13 barcode?
An EAN-13 barcode represents a 13-digit GTIN-13 identifier. It does not normally store the product name, description or price directly.
Does an EAN-13 barcode contain the product price?
Normally, no. The price is generally stored in a connected database and retrieved using the product identifier.
Does EAN-13 contain the product name?
No. The product name is normally stored in a database associated with the identifier.
What is the last digit of an EAN-13?
The final digit is the check digit, calculated using the applicable GS1 check-digit algorithm.
Does the first part of an EAN-13 show the country where the product was made?
No. The GS1 Prefix does not indicate the product’s country of manufacture or origin.
Is EAN-13 the same as GTIN-13?
EAN-13 is the barcode symbology commonly used to represent a GTIN-13.
Can an EAN-13 barcode prove authenticity?
No. A barcode alone does not prove that a physical product is genuine. Authentication requires an appropriate verification process.
What is 91iD™?
91iD™ is an independent product identification and verification network with its own structured product-identification architecture.
Is 91iD™ a GS1 barcode?
No. 91iD™ is independent of the GS1 identification system and should not be represented as a GS1-issued GTIN or EAN-13.

🚀 Final Takeaway
🔍 The Barcode Is an Identifier, Not a Complete Product Database
The easiest way to remember the concept is:
🏷️ EAN-13 Barcode
⬇️
🔢 Represents a GTIN-13
⬇️
📷 Scanner Reads It
⬇️
💻 System Decodes the Identifier
⬇️
🗄️ Database Finds the Product Record
⬇️
📋 Product Information Is Displayed
So when you scan an EAN-13 barcode and see a product name, price or other information, that information is generally coming from a connected database, not directly from the black-and-white barcode pattern.
For businesses exploring digital product identity and online verification, 91iD™ at 91id.in provides an independent approach where a structured product identifier can be connected with an online product record.
